In the Spring, I have counted 136 different kinds of weather inside of 24 hours.
In the northern hemisphere, spring has arrived, but many parts of the U.S. can’t seem to shake off winter. No matter what season of the year, strange weather events occur in every corner of the globe. In Oak Meadow’s coursework, observing seasonal weather and its effect on plants and animals is a significant part of the kindergarten, first grade and second grade science lessons. In the third grade science curriculum, weather conditions are studied by tracking weather and clouds, learning about lightning and thunder, and engaging in educational activities and artistic exercises in relation to tornadoes, blizzards, and hurricanes (or typhoons). According to encyclopedia.com, the definition for extreme weather is a weather event such as snow, rain, drought, flood, or storm that is rare for the place where it occurs.
For additional information on weather, meteorologist Crystal Wicker created an informational site for children called Weather Wiz Kids. Kids Discover also created an interactive iPad app for kids, which displays the most extreme forms of weather on Earth. It includes an interactive cross-section of a hurricane, HD videos of tornadoes and lightning, and the science behind extreme climates.
In addition to the serious side of extreme weather, you might like to read the book, Thunder Cake, written by Patricia Polacco. It is a heartwarming and beautifully written story about Patricia (the author) when she was a young girl, and how she overcame the fear of storms with the help of her grandmother. You can also introduce some fun ways we use the weather through idioms and phrases, such as under the weather, weather the storm, or fair-weather friends. It might be a great time to include a spelling and vocabulary exercise on the difference between weather,whether and wether.

Happy March Equinox Everyone!
Humankind’s imagination is as vast as the solar system we live in! Out of our imagination comes tools for working, farming, and building. If we let our imaginations soar we become inventors. In fact, inventive thinking and problem solving is something we do everyday. We see a problem and come up with a solution. In the Oak Meadow 5th grade science curriculum, students study technology and design and work on their own inventions. It’s so much fun to see what they imagine and bring into the world! They construct things that help with a job around the house, create toys for pets, and design many other practical and useful items. Humankind just seems to long for answers to questions!
Long ago astronomers sought answers to the many questions about the universe. When an answer wasn’t in sight, they imagined and created stories or guidelines for their lives. They imagined stories about the stars they saw in the night sky, imagined the sun went to sleep each night, and imagined the world was flat. In future years we have come to understand more about the universe through observation. In observing the rising and setting of the sun, astronomers imagined a great dome over the Earth’s sky and called it the celestial sphere. They imagined the celestial equator as being in the middle of the north and south poles and right above the Earth’s equator.
During the March equinox, when we have twelve hours of daylight and twelve hours of darkness, “the sun crosses the celestial equator, to enter the sky’s Northern Hemisphere. No matter where you are on Earth (except the North and South Poles), you have a due east and due west point on your horizon. That point marks the intersection of your horizon with the celestial equator, the imaginary line above the true equator of the Earth. And that’s why the sun rises due east and sets due west, for all of us, at the equinox. The equinox sun is on the celestial equator. No matter where you are on Earth, the celestial equator crosses your horizon at due east or due west.”
Oak Meadow’s k-8 teacher, Sarah Antel, shared this wonderful article on her thoughts regarding the tapping of maple trees. I hope you enjoy reading her wit and wisdom on the subject of the “Sugarin’ Season”!
It is hard to imagine on a subzero day, but trees will soon be ‘waking up’ as their life-giving sap starts to flow from the roots, where it was stored in the shortening days of autumn, to the leaf buds awaiting to unfurl. One tree in particular in the Mid-West and North Eastern United States and Canada provides more than beautiful scenery.
The Sugar Maple, Acer saccharum, is tapped this time of year so humans can harvest its sap; the liquid will ultimately be boiled into maple syrup or maple sugar. The Sugar Maple is tapped because its sap has the highest sugar content relative to other tree species (2%-3%). North America is the primary producer of maple syrup. The weather is ideal for this sap flow; the nights are below freezing so sap stops flowing, and the spring days are warm and often sunny, which encourages sap flow. A weather pattern such as this prevents the tree from turning sugars to starch. Once the nights are above freezing, and the days warm into the 50s, the sap will turn and is no longer ideal for making high quality maple syrup.
The modern maple sugaring industry has made sugaring an efficient and scientifically driven business. However, many of the tools used now still have distant roots in their ancestry. The Native Americans were the first people to make maple syrup. There are many stories of how this wonderful tradition was discovered. One story tells of how a warrior sunk his tomahawk into a tree trunk and water flowed out; his wife then boiled meat in the water and it made syrup. Another legend tells of a Native American finding a sweet icicle formed from the liquid of a broken maple branch.
Native Americans’ methods of making syrup were rather ingenious. Some tribes collected the sap in birch bark baskets or hollowed out logs. They allowed the liquid to freeze overnight, then they removed the layer of ice as the sugar did not freeze. Several nights of freezing and removing the ice left them with a much sweeter liquid as the sugar content became higher. Another method, which may have been paired with the ice removal, involved adding hot rocks to the sap; this would cause the sap to boil and the water to evaporate. The sugar again became concentrated and the liquid thicker.
Today, no matter a person’s level of technology, the methods of making maple syrup remain essentially unchanged. If you live in a part of the world where the weather allows for maple sugaring, you can make your own syrup with just a few buckets to collect sap in. If you do not live in a maple producing region, you can still include this rich lesson in your curriculum. Sugaring has so many cross curricular connections; one can explore density, history, measurement, botany, nutrition, geography, etc. The list goes on!
Whatever you choose to do with the information, enjoy sugaring season where ever you are, and the next time you put maple syrup on your pancakes, you will know a bit more about where your food came from.
This is a special guest post by Oak Meadow K-6 teacher Meg Minehan.
Meg Minehan is an Oak Meadow teacher for grades K-6. She currently homeschools her own children using the Oak Meadow curriculum. Meg co-leads a monthly forest and fields program for preschoolers in Chester, Vermont. She embraces winter by cross country skiing and sweating in her woodfired sauna.
Although all of us at Oak Meadow extol the benefits of getting children outside, we also recognize that getting young ones outdoors in winter can be quite challenging! Here are some helpful hints to help you and your children embrace these blustery, and for some of us, downright frigid days.
Perhaps most of you are familiar with the oft-quoted saying, “There’s no such thing as bad weather…” Although my feelings about that quote can change depending on my mood, the wind speed, and the type of precipitation I am about to endure, it is important to acknowledge that wearing appropriate clothing in winter is a must. These past few weeks, you may have encountered temperatures that are too cold to be safe. Most days, however, can be safely enjoyed, if only for a short time, provided you and your children are clothed appropriately. But even after investing in or, better yet, inheriting quality outdoor clothing, how do you entice children and their caretakers to go outside?
For many children, a fresh snowstorm is usually a welcome invitation to play outdoors. There are the obvious tried-and-true activities, such as sledding, snowman making, snow fort building, snowshoeing, and skiing. Now that my children are older, ages 16, 13, and 10, these are some of their favorite activities. I no longer need to encourage them to go outdoors. In fact, usually I am calling them in, so we can get some of our Oak Meadow work done. When my children were young, however, this wasn’t always the case. Sometimes they needed a hook, something to entice them to “get out and blow the stink off ye.” (quote courtesy of my father, Ed Minehan) Here are some ideas that worked, at least some of the time, for my family.
Get Moving and Follow the Tracks: On the coldest days, the only option was to keep moving. Even getting out for a short hike or snowshoe was still worth it. To keep things interesting, we often went tracking. Because we live near the woods, this was, admittedly, pretty easy for us. But driving to a special trail adds a sense of adventure too. First, spend a little time familiarizing yourself with tracking patterns. Is the animal a straight walker, hopper, waddler, or bounder? Kids can practice walking in these styles as well. Next, examine the print of the animal’s foot. Notice the shape and size. Can you count the toes? Are their claws present? What other nearby animal signs or clues can you spot? To maximize child participation, I made each of my kids a laminated detective tracking card with pictures of the four patterns and common prints. I photocopied our cards from the Shelburne Farms Project Seasons book. There are many great tracking guides or cards available. We approached each tracking expedition like a mystery. As they got older, my children became more interested in the C.S.I. scene. They loved following the tracks and searching for evidence of last meals. Yes, sometimes the results were a little gruesome, but always exciting.
Curriculum Extensions: Keep in mind these snowy mysteries can lead to imaginative storytelling, story mapping, further research, and investigative writing projects. These activities can easily be integrated into science and language arts lessons. Talk to your Oak Meadow teacher about substituting assignments. We want you and your children to embrace winter too!
Trail Games: Simple trail games are another way to keep things interesting on a cold winter walk. One of my favorite games is Christmas Tree for a Mouse. I learned it from Rachel Carson’s Sense of Wonder. As we walked through the woods, we would look at various trees, gauge their relative sizes, and decide which animal would be perfectly suited to which tree. This can be a fun way to talk about the animals that live in your area. This game could be easily modified if Christmas trees aren’t part of your family’s traditions. Maybe you could find the tree with the best treehouse option for a mouse, a mink, or a bear. If you and your child are feeling really ambitious, you might even assist with the building process.
Winter Art: Scavenger hunts and treasure walks were also a good way to build enthusiasm for a cold winter walk. After collecting simple treasures, such as pine needles, cones, and winter berries, we would put them in a mold with twine or raffia hangers, fill with water, and wait for them to freeze. We’ve used mini-bundt pans for wreaths, but silicone molds work even better. These lovely ornaments or sun catchers can be hung nearby. Quite often, however, I would encourage us to share our decorations with the birds and squirrels. Aha! Another “excuse” to get out for a walk.
Finally, on those days when everyone needs a little extra enticement, there is nothing like the promise of homemade hot chocolate and a favorite board game awaiting. Happy winter!

As I sit here this evening with a winter storm warning in effect for my area of New England, I am once again fascinated by how these tiny snow crystals can impact whole regions of the United States.
Some of you may have read The Long Winter by Laura Ingalls Wilder. That story is about an actual winter storm that raced across the prairie lands of the United States in the winter of 1880-1881. In his book The Children’s Blizzard David Laskin gives an account of the deadly prairie blizzard of 1888 and he also gives an excellent description of the different types of snowflakes there are and what the conditions are that create them. I highly recommend it if you are interested in the science of snow!
The Native American Indians had many ways to predict the weather by observing what was happening in the natural world around them for clues. In the 1880’s the weather news was sent via telegraph across the United States from Army base to Army base. The weather often arrived before the news of its coming. Today we have the National Weather Service and technology to help us predict storms and to warn us of storms.
If you are interested in learning more about snow crystals, go to your library and find the book Snowflake Bentley. You may also want to visit snowcrystals.com.
The way a crow
Shook down on me
The dust of snow
From a hemlock tree
Has given my heart
A change of mood
And saved some part
Of a day I had rued.
This time of year I start thinking about the birds in my area. The temperatures are dropping close to freezing. I see birds in great flocks swooping into the bird bath and landing on the feeder. Last week there were about 15 Common Grackles splashing and crowding into my bird bath. The winter is upon us here in New Hampshire. The birds need to eat quite a bit of food to keep up their energy for traveling south. Those that stay will need food all winter. I often look out the kitchen window in the winter to see a little black -capped chickadee at the feeder, and I wonder how it can keep warm. The tiny little feet and the skinny little legs look so vulnerable. They need high energy foods and lots of it! I know there are Oak Meadow students that enjoy watching and feeding the birds. If you do also, then you might like to join the Project FeederWatch that is a program of the Cornell University Lab of Orinthology.
“Project FeederWatch is a winter-long survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America. FeederWatchers periodically count the birds they see at their feeders from November through early April and send their counts to Project FeederWatch. FeederWatch data help scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance.“
Here’s one: The Common Grackle often allows ants to crawl over its body so that they may secrete formic acid, which is thought to kill parasites, a practice called anting. Besides formic acid from ants, the Common Grackle has been observed using various other substances, such as walnut juice, mothballs, lemons, limes, and choke cherries in similar ways.
Do you watch the birds? Do you keep a list of the birds you’ve seen? Let us know!

I’ve been thinking a lot about turkeys lately! If you are in the United States, you might be celebrating the Thanksgiving holiday on Thursday. It is a celebration of thanks commemorating the first harvest feast the Pilgrims had in 1621. Today families often gather to have a big feast of foods and that meal might include a roasted turkey. So, I’ve been thinking about turkeys.
One of my first thoughts led me to wonder where the word “turkey” originated. Why are they called turkeys? An article in the Atlantic Monthly had a good explanation. You can read it here. I was pretty surprised to find that the origin of the word is debated by etymology experts.
Then I was wondering if turkeys can really fly and I started to investigate. Sure enough, they can fly! This investigation led me to thinking about the wishbone in the turkey at our family Thanksgiving celebration. It’s the “wishbone” that is the bone that connects the wings of birds allowing them to fly.
So what do Tyrannosaurus Rex, the Velociraptors, and turkeys all have in common? I was amazed to find out that many dinosaurs, including the newly found “Mud Dragon” had wishbones. Yep! The wishbone is actually called the “furcula” and is found in birds and in DINOSAURS!
Thanks to Oak Meadow’s K-4 teacher, Sarah Antel, for this wonderful addition to our blog.
As autumn finally settles in Vermont, I always notice mental and physical changes in myself. I am found in the kitchen making soups, stews, and bread, I pick up the handwork I abandoned last spring with renewed interest, and I often feel fatigued as the early evening darkness falls; a purring cat on my lap helps this state of calm occur more easily.
Even though it may seem many plants have died outside with a morning frost, I see this season as a time of rest and ultimately, renewal. A good rest often helps one to rise refreshed and ready to work. Winter is nature’s time to rest. The trees have dropped their leaves and stored the food they made in their roots, plants of all kinds have scattered their seeds, and many animals are nesting in warm places, preparing for the winter respite.
As winter draws near, people often remark that animals are getting ready to hibernate. This statement is only accurate for a handful of animals here in the Northeast. If animals do not migrate or stay active in the winter months, many enter a state of torpor, or light hibernation during the colder weather; most do not hibernate.
An animal that is considered a “true hibernator” stores fat reserves, their breathing slows to as little as one breath a minute, their heart rate often registers at four beats per minute, and their body temperature lowers close to the temperature of the surrounding air. Often, these creatures will not awaken, even if they are handled. The only animals that are true hibernators in the North East are bats, groundhogs, and jumping mice. Many other animals, including bears, go into torpor. These animals’ bodies stay very close to their normal temperatures. Additionally, their breathing and heart rates do not slow. They are easily awakened and will often be found foraging for food during a warm spell. Reptiles, like snakes, can be found in dens in a state of torpor, but they will sometimes be seen warming themselves when the sun’s rays beckon. Amphibians bury themselves in the soil, often at the bottom of a pond. But these creatures also can awaken during the winter as some people have spied them moving about below ice.
Although the winter season may seem like a silent time for nature, there is still an abundance of activity and life beneath the blanket of snow. If you live in a place where snow falls in the winter, you may want to set up a subnivean zone board so you can observe some activity that happens below the snow. Once there is some snow on the ground, lay a wide piece of wood like a large piece of plywood, over some seeds you sprinkle on top of the snow. In a few days, gently lift the board to peek underneath. Many of the seeds may be gone and you may see a network of tunnels under the board. The subnivean zone is the area in and underneath the snowpack where some small mammals like mice, voles, and shrews live out the winter and forage for food. Staying in the subnivean zone helps to protect them from predators and insulates them from the cold winter air. Sprinkle more seeds throughout the winter so these creatures can have a place to find food and you can make scientific observations all winter-long.

In November of 1895, Alfred Nobel passed away and left a very large amount of his money to go toward a variety of prizes. The prizes became known as the Nobel Prizes. It was a generous beginning to yearly honor work in the sciences, literature, and those people working for peace throughout the world.
I am always most interested in The Nobel Peace Prize. Alfred Nobel’s will stated that the Peace Prize would go to “the person who shall have done the most or the best work for fraternity between nations, for the abolition or reduction of standing armies and for the holding and promotion of peace congresses.”
The 2017 award went to an organization, rather than one person. The Nobel Peace Prize 2017 was awarded to the International Campaign to Abolish Nuclear Weapons (ICAN). This is a world-wide partnership of organizations dedicated and focused on a nuclear weapon ban treaty for the world. What an honorable intention to free the world’s people from the use of a nuclear weapon.
In 1904 Ivan Pavlov won the Nobel Prize in Physiology or Medicine. Some of you may have already studied about him and his ideas. You may be studying Pavlov’s work in the Oak Meadow curriculum. On the Nobel Prize website there are educational pages that have some fun facts and games to play. The one about Ivan Pavlov is great!
Oak Meadow’s science coursework in grades k-4 includes various studies of the butterfly. In addition to the suggested lesson activities, you might include a guidebook, such as Robert Michael Pyle’s book, National Audubon Society Field Guide to North American Butterflies. Perhaps you would enjoy sharing a butterfly story, such as Alan Madison’s Velma Gratch and the Way Cool Butterfly or Eric Carle’s The Very Hungry Caterpillar or Bruce Coville’s The Prince of Butterflies.
Help track Monarch migration!
Awareness of the threats to pollinating insects is growing, and these beneficial pollinators need our help now more than ever. The Monarch butterflies have seen a population decline over 90% in recent years. Researchers and citizen scientists have been tagging the beautiful, graceful Monarch butterflies for many years. In fact, back in the late 1970s, tagging led to the discovery of the Monarchs’ wintering ground in Mexico.
Oak Meadow students have the perfect opportunity to participate in a Citizen Science project that can help to monitor an important population of pollinators. Here are a few sites that offer ways to assist in this exciting Monarch migration:
