Nature Journal Notes

Nature journals help us to focus our thoughts and keep ourselves organized, which means they are the ideal tool to help us start a research project! Inherently, nature journals show us change over time either of many places or of one place in particular. Because of this, it makes it very easy to convert our nature journals into scientific journals where we can put hypotheses, predictions, detailed observations and findings!
Hypothesis:  an educated guess designed to  further investigation. Usually based on previous observation/investigation.
 
A fun way to incorporate the scientific method into our nature journals is by setting up a research project. This idea is taken from Clare Walker Leslie and Charles E. Roth’s Keeping a Nature Journal.

If you ever find yourself particularly interested in a specific plant, animal or phenomenon while outside (or inside) journaling, use it as an opportunity to do a little bit of research! Nature journal research projects can be about anything and they are yet another way to help us focus our thoughts and learn more about the natural world around us!

Once you have an idea of what you would like your research project to revolve around, there are a few things to keep in mind. The first is that you are going to try to make as many field observations as possible in your journal, which means that your project should revolve around something you can observe on multiple occasions. Pictured is an example taken from Clare Walker Leslie of multiple observations made of the Gray Squirrel.

Something you’ll want to do before pursuing your project is to research the plant or animal you are investigating by trying to get as much information on it as possible. For this, you can utilize your local library, books you have in your home and/or the internet! If you want, you can create a page (or more!) of background information in your journal with all of the new things that you learn about your research subject! As you gain more information on the plant/animal you are looking into, you can compare what you learn through independent study of books/website and what you observe when in the field. Do your observations align with what you are learning? Do you notice anything unique that you didn’t read about? Does anything surprise you about your plant/animal?


A huge part of science and ecological studies is observing how plants and animals behave in their natural environments over time. Committing to sketching, recording, researching and making connections of one aspect of the natural world through a mini-research project will help to enhance so many skills that are utilized in our nature journals and it can be a TON of fun! You'll probably see a lot of things that you hadn't noticed before and perhaps you'll even make a discovery!

Creative (treeative?) ways to use your balsam fir all year long!

12/31/2020

​It is the end of December, which means people are getting rid of wreaths, Christmas trees and all things festive. I am always saddened when I have to throw out trees and wreaths because it usually means saying goodbye to the lovely balsam smell that comes with them. If you are like me and you love the balsam smell, here are some cool crafts you can do with balsam branches and needles! If you love the smell of balsam and don’t have a tree or wreath, you may be able to convince a friend to give you a couple of clippings or you could go out looking for balsam fir trees! According to iNaturalist, there are balsam trees in Massachusetts! Of course, don’t go cut down a tree, but even pine trees shed their needles, so chances are if you find a fir tree, there are balsam needles below it! Just be sure to check the rules/guidelines about where you are visiting and if it would be acceptable to forage for some balsam needles!
           
​I usually smell balsam trees before I see them when I am out wandering, but some other characteristics to help you identify a balsam fir are flat needles that are about ¾ inches long and very dark green in color. The bottom of each needle will be lighter and more dull looking with white lines on the underside. Eastern Hemlocks can look like Balsam Firs, but their needles are much shorter (less than ½ an inch) and they won’t have the classic balsam aroma.


Alright, once you’ve found your acceptable source for all things balsam, here’s what you can do:
Picture

Clip and dry the needles!

Picture
To get the best balsam smell for the longest amount of time, you should cut and dry your needles. This is super simple and step one is to grab some scissors and shred all of your needles into tiny pieces! Needles should at least be chopped in half once to enhance the forest-like aroma. Once the needles are chopped, you will want to dry them. To do this, lay your choppings on a pan and leave them somewhere dry and undisturbed for a couple of days. When you come back to your needles, they should be brittle to touch and fairly easy to snap. Hopefully wherever you put them to dry now has a strong balsam scent! Once you are sure your needles are dry, they should be good to store and smell for a pretty long time! I have a balsam pillow going on four years old that is still very strongly scented.

​What you do with your needles next is completely up to you! If you are feeling extra crafty, or want to explore the world of sewing, you can make a balsam pillow with two pieces of fabric. You can also reuse cotton baggies, or jewelry sachets and fill them with your balsam clippings. Possibly the easiest way to fill a room with the smell of balsam is to put all your clippings in a decorative bowl and let the aroma fill the air! However you choose to use your needles will be perfect!

make a weather stick!

Picture

 The wood of Balsam Fir trees is very responsive to its environment and some of the cell structure in the tree will actually change depending on weather! Specifically, the cells will expand or contract based on the amount of moisture that is in the air. Because of the expanding and contracting of the cells, the trees will actually change shape under different weather conditions. To learn more about how Balsam Firs react to changes in weather, check out this article published in the Farmer's Almanac!

​So, how can we harness this prediction tool? Great question! Below are instructions on how to use the power of the balsam fir to create your very own weather stick! This activity is best to do with an already cut down Christmas tree so that you aren’t chopping off branches of trees growing in the wild.

​The first thing you’ll want to do is find a branch on your tree that is about ¼” in diameter and cut it from the trunk of the tree. Next, you’ll need to strip the branch completely bare. This means clipping all of the smaller branches that are attached to it off and taking all the needles and bark from it! Once your branch Is stripped, you’ll need to leave it out to dry for a couple of days.

​While your branch is drying, you can work on creating a mount for your weather stick. Weather sticks seem to work best if they hang perpendicular somewhere outside, so you want to create a mount that you can attach to a wall or something outdoors. Many people suggest finding a block of wood and drilling a small hole in it that is the same width as your branch. You can then slip the branch in the hole with a bit of wood glue and, viola, you’ve got a weather stick! Don’t have access to a drill? Get creative! The main thing is that your balsam fir stick is free to move about as the weather changes. When you hang your stick, you’ll want to put it upside down from the way it was growing on the tree. It’s most likely that the stick was curved a little bit upwards when It was on the tree, so you’ll probably want to hang it so that it is pointing towards the ground.

​After you’ve found a permanent location for your stick, you’ll be able to use it to help you make weather predictions! Whenever your stick is pointing down it means that there is moisture in the air and the possibility of rain and whenever the stick is pointing up it means that there isn’t moisture in the air and the probability of rain is low!

Ah yes, it is the end of the year (a little unbelievably), which means it is time for New Year’s Resolutions and lots of self-evaluation in the coming days. This attitude of self-reflection and future aspirations is something that can trickle down even into our nature journals. Personally, I do not put much thought into New Year’s Resolutions, but I do like to use the end of the year as a time to reflect and look back at some of my accomplishments as well as think about suggestions for myself in the coming year. Many times, nature journals serve as the perfect outlet for in-the-moment observations and recordings, but then they tend to stay in that moment. I find that I don’t often look back at my previous nature journal entries unless I make a point to do so, or if I am trying to get information about a specific date and time.
​

With the end of December comes an opportunity to re-live the past year through the pages of our journals! While leafing (pun intended) through your journal, keep your eyes open for things that you enjoyed or maybe entries that weren’t as gripping to you. Do you remember writing all of the entries, or are some of them much more memorable than others?

Picture
Picture
You can keep a list of the things you notice about your recordings that you liked and some things that you would like to improve on. I will be the first to admit that it can be tricky to go through old work and critique/appreciate what you've created, but as naturalists, it can be a really helpful tool to improving work for the future! You can also take note of styles that you used throughout the year that you really enjoyed, or perhaps there was something you had wanted to do but didn't get to. For me, I would like to try to incorporate more watercolors into my journal and practice with that new medium. It is something I am always thinking about while journaling, but have never taken the time to explore! 
​
If you'd like, you can add your list of thoughts/comments about previous journal entries into your current journal so that you can reference it moving forward as a helpful reminder, but whether or not you want to record your findings in your journal is completely up to you! If you're new to journaling, or aren't sure that nature journaling is for you, the beginning of 2021 could be the time to explore this interest! We have a bunch of Nature Journal Notes blog posts all about different things to try in your nature journal as well as tips on some important pieces of information to keep in mind while recording data and observations!

Swing by next week for more Nature Journal Notes and enjoy a selection of our Nature Journal Note examples from the past year below!

​One fun and unique way to challenge ourselves in our nature journals is by dabbling in the art of poetry! Many renowned naturalists through the ages have used poetry as a form of expression when recording their observations and feelings and the relationship between the two. Henry David Thoreau, Mary Oliver, Beatrix Potter, and MANY others combined poetry and ecology in their everyday lives.

​When writing in our nature journals, there are tons of forms of poetry that we can experiment with. In general, poetry is any writing that expresses feelings through style and rhythm. Because of its constant beauty and wonderment, nature provides a perfect muse to evoke a variety of feelings.

​Practicing with poetry is easy and is something that is often overlooked, but can be a very good way to capture moments in nature and focus on specific observations. One fairly straightforward exercise can be to create an acrostic poem. The format of acrostic poems is simple. Take a work or phrase, preferably nature related, vertically in your nature journal. Then, use each letter of the word as the first letter for a set of horizontal words or phrases that relate to the vertical word. For the sake of nature journaling, you can practice with recording your observations of the vertical word in the form of horizontal phrases like the examples below!
​

​Another simple, yet thoughtful  style of poetry is the Haiku. A Haiku is a form of Japanese poetry that is commonly a three lined poem with 5 syllables in the first line, 7 syllables in the second line and 5 syllables in the third line. Haikus are perfect for reflecting on nature because they are designed to focus on imagery. Try to write a Haiku about something you are seeing in nature sticking to the 5-7-5 syllable format. Think about sound, sight, touch, smell and possibly even taste when coming up with phrases. Below is a haiku by Japanese poet, Natsume Sōseki.
​

over the wintry

By ​Natsume Sōseki

​Over the wintry
Forest, winds howl in rage
With no leaves to blow.
​


​The beauty of poetry, much like the beauty of keeping a nature journal, is that it can really be whatever you want! My favorite type of poem to play with are those that rhyme, but even with rhyming poems, there are infinite ways to express yourself! Take some time to explore different ways to record observations in the form of poetry. Even if poetry is completely new for you, or maybe something that you won't experiment with in the future, it can be an awesome tool for focusing your observations. Until next week!

It's officially winter now that we've had our first large snowfall of the season, which means there is plenty of opportunity to get outside and start building snowmen, snow forts, and making snow angels! It seems like the fun never ends when there is a layer of fresh snow coating the earth. There's no better way to keep our bodies moving and our energy up than a nice break to make some maple syrup taffy! Check out the super easy snack instructions below and enjoy!

Things to grab for this activity: Maple syrup, an area of untouched snow, a saucepan for your syrup, a spoon and some popsicle sticks (if you wish)! Additionally, you will need an adult helper.


maple syrup taffy


​Making maple syrup taffy after a fresh snow fall could not be easier if you have some maple syrup to spare!​ Aside from the syrup, you will need some clean, fresh snow, a saucepan, a spoon and some adult help/supervision to heat up the syrup.

First, pour however much syrup you'd like to make taffy with into your saucepan and heat it up on medium-heat for about four minutes. You may need to stir it occasionally to keep it from boiling over.

Picture
Once the syrup has been heating up for four minutes and before it has time to cool down, pour it into the fresh patch of packed snow! You can pour it as is, or find some popsicle sticks to lay out as handles to make lolli-pops. Flex your creative muscle by trying to make fun, festive shapes! As soon as the candy cools enough so that it feels hard and sturdy enough to pick up without dripping, it is ready to eat!

​With winter storms comes great opportunity to examine and think critically about the wonder that is snow! What a better place to do this than within our nature journals? Snow is a pretty general term used for white, frozen precipitation that flurries from the clouds, but it can come in all sorts of shapes, sizes and textures! In the perfect conditions, snowflakes can be up to two inches long!

What you should know about snow:

​1. Snow cannot be formed if temperatures are above freezing, 0 degrees Celsius or 32 degrees Fahrenheit, but it is never too cold for snow to form if temperatures are below freezing!

Picture

​2. ​All individual snowflakes are hexagonal, which means six-sided, in shape. This is because water freezes with a hexagonal structure and is the unique reason why ice-cubes are less dense than water! Typically, solids are more dense than liquids.
Picture

​3. Although all snowflakes follow the same general formation structure, no two snowflakes are identical… ever!

​So, how can we examine snowflakes in our journals? The first think you can do, and this can be with ice or snow, is go out and find areas where there is evidence of frozen moisture. Try looking in a variety of different places and then record, either by sketching or writing down observations, some of the similarities and differences you are noticing between the formation/accumulation of ice/snow. This year, we haven’t had too much snow accumulation, but ice tends to pop up in some really cool places and can look very different depending on where it is! For instance, below is ice on a pond, ice on a leaf and ice that has formed in the mud (mud ice is called needle ice and it is my favorite kind of ice to examine due to its awesome hexagonal, needle-like pillars).
Picture

Picture

​If it is actively snowing outside, you can actually “catch” snowflakes and examine them up close to see what kind of shapes they form! All you need to do this is a black piece of paper, a small space in a freezer for the paper, a magnifying glass and, of course, your nature journal!

Put the black construction paper in the freezer for at least a couple of hours so it is nice and cold! Then, bring the construction paper outside with you while it is snowing and “catch” some of the snowflakes on the construction paper. Use a magnifying glass to examine the different shapes and try to notice the hexagonal structure! Next, sketch what you are seeing in your nature journal! This activity was taken from WeatherWizKids.com and is a great place to explore other awesome, weather-related activities!

Do you have any questions you want to write in your journal? How long can the snowflakes stay on the paper before they melt? Are all of the snowflakes the same size? Have a great time exploring snow and enjoy the upcoming winter weather!

Winter Birding!

12/10/2020

​When thinking about birds for the winter, we are often reminded of migration and tend to overlook the birds that stay active and fed during the harsher months of the year. There are quite a few of year round bird species who have no need to travel south and continue to live their lives in Massachusetts and other northern areas undisturbed. We also often assume that migration is the movement of animals to warmer climates, but it is actually the movement of animals following their food sources.
​ 
Many times, warmer climates provide food sources that are unavailable for birds (and other animals) during cooler months. Species that have a broader diet are going to be able to find food more easily as temperatures and availability change. That being said, there are some animals that are in a constant state of migration! Animals like whiles are always on the move following their food source and continually migrating, but today, we will explore a little bit about some of the birds that are seemingly undisturbed in the winter here in Massachusetts.
Picture
​ 
Activity certainly slows down during the winter months, but if you know where to look and what to look for, you will find that some animals are still up and about continuing with their daily routines. Of course, the animal we are focusing on right now is birds! Not all birds stay in MA for the winter, but quite a few do and we are going to explore why they are able to do this!
​ 
Our investigation will start with the physical adaptations that allow birds to stay, or the traits that they have that are part of their bodies that allow them to survive throughout the winter.

​Birds are Endothermic!

​Endothermic animals are animals that are able to produce their own body heat and maintain the same temperature all year round. Birds and mammals are the only endothermic groups of animals, which is why they tend to be the most active during cooler weather conditions. This is also why when humans, or our furry friends (dogs, cats, etc.), go to the doctor’s office, it is important to take our temperatures and make sure we are staying the same temperature! The ability to produce their own body heat is key when being able to stay active in the cold.

​
 Feather Structure!

​
Birds have multiple layers of feathers. The outermost layer are flight feathers and protective feathers that keep water and moisture from getting to their skin. The layer of feathers underneath this protective layer are called down feathers and help to trap body heat! Many humans steal this specific adaptation in the form of down jackets, which we wear during the winter to trap our body heat. Birds that spend more time in harsher, cooler conditions will have thicker down feathers and a stronger protective layer. Ducks and Geese, who spend much of their lives in the water, will have extremely fluffy down feathers as well as almost an armor of more structured feathers surrounding them.
Picture

​Beak Structure!


The birds that stay active in cooler climates during the winter have beaks that allow them to forage for a variety of different food sources, or the ability to eat food that is available in the winter. One bird I often think of when I consider beak structure is the hummingbird! Hummingbirds will definitely travel south for the winter because they need to get their food from flowers. Their beaks are such a shape, that it is impossible for them to consume food besides nectar. If we think about where flowers will be available, it is in climates that stay warm. This is probably why people think of migration as moving to warmer climates, not following food.

​Tufted Titmice, Cardinals, Blue Jays, Chickadees, and Dark-Eyed Juncos are just some of the birds that stick around in the winter and they can all be seen visiting backyard bird feeders! They have beaks that allow them to eat different seeds and nuts especially the ones put out by humans in the winter!
Picture

Some birds have the ability to go into a state of torpor on very cold days, but birds are not able to do this for as long as mammals. Torpor is essentially a mini state of hibernation where breathing slows, blood pressure slows and body temperature decreases. The only bird that is known to do this for extended amounts of time is the Common Poorwill, which is not a Massachusetts native and can stay in a state of torpor for weeks!
 
If you are looking for ways to attract common winter birds to your yard, just grab some bird seed and spread it on the ground! If you are looking for a more crafty way to attract birds to a specific location (possibly outside a window) you can find some kind of vessel, I like to use empty toilet paper or paper towel rolls, and put a string through them to hang. You can then cover the roll with peanut butter and sticks seeds to the outside! When watching birds this winter, try to identify some of their adaptations that allow them to stay active!

​We often associate winter with a lack of animal activity and although many critters will cope by hibernating or migrating, there are some animals that stay active during even the coldest days. If animals are able to find sources of food and water and have adaptations that keep them warm, there’s no reason for them to follow their food elsewhere or go into a deep sleep!

​Animals that are able to regulate and maintain the same temperature all year round are called endothermic. All birds and mammals are endothermic animals. Reptiles, fish, amphibians and invertebrates are ectothermic, which means their body temperature is the same as the temperature of the air around them. During the coldest months of the year, these animals physically cannot keep their bodies warm and have to go into a state of inactivity. This is why birds and mammals are the only animals we see that are consistently active throughout the winter.

​Adaptation: Something that an animal has or does that makes it better able to survive in its environment
Hibernation: A state of deep sleep that lasts for the entire winter season
Migration: The movement of animals from one area to another area while following a food source

A fun winter journaling activity to keep track of who is active near you is documenting tracks and scat! With winter comes (hopefully) a snowy canvas covering the landscape. The soft, white snow becomes the perfect place for animal footprints to be embedded and scat to contrast with the light backdrop. By knowing how to identify tracks and scat of local animals, you can learn a whole lot about the winter wanderers of your area! Before starting your animal tracks and scat investigation, it may be helpful to get a tracks and scat guide for the area where you live. If you are MA resident, here is a great online track ID guide from mass wildlife!

​Tracks:
trails of animal footprints often present in snow or soft ground.

Scat: Animal poop!

​ 
In your journal, practice sketching the different tracks and scat you are seeing. If there isn’t snow covering the ground, yet, you can begin to look for tracks in mud or areas where the ground is soft. Animal tracks come in all sorts of different shapes and sizes, so keep your eyes peeled for any kind of indents in the ground that look out of the ordinary. Usually, if you are able to find at least one animal track, there will be other tracks nearby!
Picture
​ 
Try to identify what direction the animal is headed. If the tracks you are observing have toes, the animal is moving in the direction that their toes are pointing. If you are looking at tracks with hooves, like a deer, the pointed part of the hoof is the front and will indicate where the animal was headed. Once you know the direction that your animal is headed in, you can wander that way to see if there are any more signs of the animal like more tracks or even scat!
​ 
Although it might seem gross at first, animal scat is awesome! It’s a super useful tool for knowing who is wandering through your area and what kind of food is available to the animals around. When sketching scat, take note of the shape, color and if you can see anything identifiable like fur, feathers, or berries!
 
While journaling, you can challenge yourself to make an animal tracks and scat guide of your area to share with friends and family members! You can then ask people to go out and try to find signs of these animals while they are walking around the same places!

Tough As Pine Needles??

11/24/2020

The forests of New England provide lush, dense greenery in spring and summer, but something happens in the fall that always results in the landscape looking like a monotonous mash up of grays and browns. Trees cut off the nutrient source to their leaves and in a matter of weeks they go from green, to bright red, orange and yellow, to completely bare. Except for, of course, the pine trees!

​Many of you may have noticed over the years that the pine trees sharing the forest with broad-leaf, deciduous trees do not go through the same cyclical shedding of extra weight in preparation for the winter. This is because pine trees have adapted over time to withstand much harsher weather conditions than we have in Massachusetts. The lucky pine trees that have found their way to the temperate forests of the east coast of the United States are on vacation compared to some of their relatives a little further north!

​The most common pine tree in our neck of the woods is the Eastern White Pine. There are other firs that grow in Massachusetts, but Pinus strobus is by far the most abundant. Eastern White Pines are identifiable by their long, soft, flexible needle clusters that come in groups of five. One for each letter of the word W-H-I-T-E.


​Broad-Leaved Tree: ​Any tree with flat, wide leaves
Deciduous Tree: Trees that shed their leaves after one growing season
Adaptation: A behavior or characteristic of a plant or animal that makes it better able to survive in its environment
Temperate Forest: A forest with a moderate climate that tends to have four distinct seasons: summer, winter, spring and fall
Picture

As mentioned, Massachusetts has a mix of both pine and deciduous trees, but as you travel more northward in North America, pine trees begin to define the landscape. This is because pine trees have more adaptations that allow them to be successful in cold, dry, nutrient deficient conditions year-round, whereas deciduous trees are better adapted for climates with distinct seasons such as those in New England. Looking at ecosystems further north, such as into Canada and northern parts of Europe and Russia, deciduous trees become non-existent.
 
The biome that is dominated by pines is known as the Taiga. The Taiga does not have distinct growing seasons and ranges between 23-41 degrees Fahrenheit all year round. It has long, cold winters, short summers, low precipitation and nutrient poor soil. So, how are pine trees able to survive these extreme conditions?

​Biome:
An ecological community of plants and animals that covers a large portion of the Earth

First, their behavior. Pine trees are also known as evergreen trees and this is because of their appearance of being green throughout the entire year. Unlike deciduous trees, evergreen leaves (yes, needles are leaves) live for more than one growing season. Because of this, they appear to keep their leaves forever, but we know by looking at the forest floor under pine trees that they do, in fact, lose their needles at some point. This is true. The White Pines of Massachusetts will typically drop needles every two years. Because new needles are grown each-year, not all of the needles fall off at once making it appear as though they never lose their needles. The advantage of dropping needles so infrequently is that pine trees do not have to use as much energy in the springtime to produce a whole new set of leaves. This is less important in Massachusetts, but extremely important when we think about the Taiga and lack of distinct seasons. For Massachusetts, spring is a time of regrowth when plants get more sunlight, water and nutrients, but springtime in the boreal forests, is not much different than the rest of the year and there is no influx in resources to support an entire biome’s worth of regrowth.

Second, their structure. A key characteristic of pine trees are their needle leaf structure. Needles serve the exact same purpose for pine trees as broad leaves serve for other trees. They use chlorophyll, which is why they are primarily green in color, to convert the sun’s light energy into sugar. A process also known as photosynthesis. You may be wondering, if they serve the same purpose, what are the benefits of the distinct needle-shape? Well, a pine needle is essentially a broad leaf that has been rolled up tightly around the center vein of the leaf. Just as fat keeps animals warm in the winter, these rolled up structures keep the internal workings of the leaf from getting too cold, allowing nutrients to continue to flow freely between the needles and the tree trunk.

Another important adaptation of pine needles is the waxy coating that surrounds each individual needle. This coating is to ensure that moisture does not leave the needles when the air outside is dry. If we think about when the air is driest, it is usually during the winter time. Cold air holds less moisture than warmer air and humans are a great example of an organism that gets dried out as the air gets colder – just think about your hands and lips in the winter! The waxy coating of the needles is not the only adaptation of pine trees to conserve moisture. The bark is also extremely important for pine trees when storing water. Next time you are in a mixed forest, compare the bark of an evergreen to that of a deciduous tree. What do you notice? Hopefully, you will observe that the pine tree bark is much thicker, which is just another adaptation that keeps the trunk of the tree warm and prevents moisture loss to the cold, dry air of the Taiga.

 The last point I will mention about structure, although there are many more, is the overall shape of most evergreens. When we think evergreen, we typically picture the triangular-like tiers of a Christmas tree. The top of the tree is very small and gradually gets wider towards the base of the tree. This shape is imperative to the survival of evergreen pine trees during times of excessive snowfall. If the tops of pine trees were as wide as the bottoms, or wider like in the case of many deciduous trees, the snow build-up would be too much weight for the tree to handle and it would most-likely bend or snap with the added pressure. Because the trees have a conical shape, there is minimal snow build up at the tops of the trees, and it is the bottom branches that are burdened with most of the weight from excessive snowfall. The branches at the base of pine trees also happen to be the oldest and sturdiest of all the branches meaning that they are most-able to handle the extra weight!

And finally, pine trees have an exceptionally cool way of dispersing, or spreading, their seeds to ensure the survival of future generations. Each scale of a pine cone is home to one seed of a pine tree (also known as a pine nut) and together, the many scales create a protective structure known as the cone. When conditions are dry, pinecones will open up to drop their seeds, but if conditions are wet and not favorable, the pinecones will close so as not to drop the seeds at times when they may not survive. This is something we can observe when looking at pine cones in Massachusetts. If you stumble across a cone bearing pine tree during dry weather, you will notice the individual scales will be spread out so that seeds can drop with ease. On the contrary, if you come across a pine tree on a rainy day, you will notice that the cones are tightly closed so as not to drop the seeds when they might drown from too much water!

Evergreen pine trees are tough and everything about them is to ensure their survival in areas where many other plants and animals struggle to thrive. Can you think of any other adaptations that pine trees may have to help them combat harsh weather? Next time you are walking in a mixed forest, try to find a pine tree and a deciduous tree to compare with each other! Do you notice any adaptations about the deciduous tree that makes it better able to survive the changing seasons?

Nature Journal Notes

When making recordings and observations in nature journals, emphasis is often put on what people can see and not so much on what they can hear. Today's exercise is all about changing perspective and, in fact, eliminating the element of sight altogether. The sounds that are associated with different seasons, environments, or even times of day can be equally as insightful and intriguing as the visual elements of an area. Below are a couple of ideas for nature journaling that focus on the different sounds within a habitat and how to capture them in a meaningful way. Being in tune with the different, natural noises of an environment can serve as a helpful backdrop when learning various animal calls, especially birds!

Before diving right into a nature journal activity, choose a spot that will work for documenting nature noises and then sit quietly, eyes closed for a minute and take in the sounds. Don't focus on journal writing. Simply sit, relax and listen. This time can also be used to record general information such as the date, time, temperature, cloud coverage, etc. These will all be helpful pieces of information when looking back at the journal entries and trying to make connections.

The first journaling activity is to track changes in sound over time. This is very similar to previously mentioned journaling activities about watching a landscape change over time, or a specific flower or leaf. Find a place in nature that is easily accessible and can be visited around the same time every day. Take a seat and begin to listen to the sounds. After taking a moment to fully embrace the area, start a timer for a set amount of time. While the timer is running, record all the noises that are happening in the environment. If any of the sounds are coming from unknown sources, try to describe them as specifically as possible. Do this exercise at least once a day in the same spot for a week and see if anything changes! This can also be done at different times throughout the day to see how the time of day affects what kinds of noises can be heard.

The next sound journaling activity is to create a sound map! Similarly to the first activity, step one is to find somewhere in nature to sit and be undisturbed while listening to the surroundings. Pull out your nature journal and follow these steps to create a map:


1. Draw yourself in your nature journal
2. Look around and see if there are any natural or man-made landmarks you would like to add to your map to help you identify where sounds are coming from
3. Start a timer for a set amount of time
4. Record all the sounds you are hearing in the designated timeframe on your map
5. Try your best to mark sounds on the map based one where you are hearing them

If you would like your sound map to be more visual, you can create a sound key as well! With your sound key, you can designate different shapes for the different sounds you are hearing. Just be sure to record what each shape represents in as much detail as possible. Although it is not necessary, it can be a lot of fun to create sound maps at different times throughout the day as well as from the same spot on different days over time. It can be an insightful visual tool for watching sounds change and move throughout an environment. You can even explore with creating sound maps in different habitats.

What sounds were different? Are there any sounds that stayed the same? Are you unsure of any of the sounds you are hearing?
