STEM Tuesday– Forests/Temperate Trees — In the Classroom

 

Trees are some of nature’s most amazing creations! Around the world, trees of all sizes and shapes are the heart of forest ecosystems. They provide oxygen, absorb carbon dioxide, stabilize soil, and serve as essential habitat and food sources for countless species. In these books, readers can take a walk through a number of different forests across the globe and join scientists and naturalists as they discover many amazing secrets of some remarkable trees. They make a great starting point for classroom discussions and activities!

 

Ultimate Explorer Field Guide: Trees

by Patricia Daniels

Introductory pages include “what is a tree?” and provide lessons for recognizing leaves. Each tree entry includes a photo of the entire tree and a close-up of the leaves or needles, flowers, nuts, cones, or fruit. Special features and “fun facts” make this more than just an ordinary field guide.

 

Classroom Activity – Tree Detective

What types of trees grow where you live? Explain to students that they will act as “tree detectives.” Using observational skills, they will identify different types of trees in their neighborhood. Students should examine features such as leaf shape, size, and edges, as well as bark texture, seeds, and the tree’s overall shape. Using a simple tree identification chart or field guide, they can compare their observations to determine the tree’s species or group, such as deciduous or evergreen. As they work, students should record detailed observations of the trees they find and explain which characteristics helped them identify them. Students can share their findings with the class or create a local tree guidebook for the classroom.

 

Forests in Danger (A True Book: The Earth at Risk)

by Jasmine Ting

From the tropics to the poles, this book looks at three forest biomes and what makes each unique. A fourth chapter examines threats to forests, from invasive species and deforestation to fires, and shares ways kids can help with forest conservation. There’s also a great explainer about carbon capture.

 

 

Forest Ecosystems (Earth’s Ecosystems)

by Tammy Gagne

Divided into 12 sections, this book takes a close look at different kinds of forests around the world and the animals that live in them. The final two sections outline human impacts on forests and how people care for forests.

 

 

Classroom Activity – Forest Threats

Forests around the world are threatened by human activities, such as deforestation, climate change, pollution, and invasive species. Divide students into small groups and have each group investigate one of the threats facing the world’s forests. In their research, students should answer the following questions:

  • What is the threat facing forests?
  • How have humans caused/contributed to this threat?
  • What damage has this threat caused?
  • What types of forests have been impacted?
  • What is the impact on the greater forest ecosystem?
  • What conservation efforts are being made to restore/repair forests?
  • How can students help with conservation?

Students can create a presentation to share what they have learned with their classmates.

 

Can You Hear the Trees Talking? Discovering the Hidden Life of the Forest

by Peter Wohlleben

This book is a walk through the woods in seven chapters. Forest explorers learn how trees work, how they grow, animals that live in and around them, and more. Each spread examines a single question: How do trees drink? Do trees make babies? Can they talk? “Look” sidebars invite readers to notice something, and “Try This” activities provide hands-on STEM activities to explore the forest around you.

 

The Magic and Mystery of Trees (The Magic and Mystery of the Natural World)

by Jen Green

This browsable book opens with a map showing where trees live in the world. Five sections explore what a tree is, its flowers, fruits, and seeds, tree habitats, its partnerships with other species, and the complexities of human-tree relationships.

 

Classroom Activity – Trees in Earth’s Carbon Cycle

Trees play an important role in Earth’s carbon cycle, absorbing atmospheric carbon dioxide and releasing oxygen through photosynthesis. Students can illustrate their role by creating a forest carbon cycle diagram that shows how carbon moves through a forest ecosystem. Consider how to answer/illustrate the following questions in the diagram:

  • Where do trees get the carbon dioxide they use for photosynthesis?
  • Where do they store carbon?
  • How does the carbon move from trees into animals and soil?
  • What is the role of decomposers?
  • How does carbon return to the atmosphere?
  • Why are forests an important carbon sink?

The Leaf Detective: How Margaret Lowman Uncovered Secrets in the Rainforest by Heather Lang

Margaret Lowman had been a leaf detective since she was a young girl. Even though most people thought there was no room for a woman in science, she went to university and conducted research in the rainforest. But to study leaves she needed to find a way to get into the treetops. Because, she said, “We had already been to the moon and back and nobody had been to the top of the tree.”

Happy New Year from the STEM Tuesday Team! The 2026 Light Bulb.

The 2026 Light Bulb

New inventions are often built on previous inventions through the power of trial and error. 

The light bulb, as we know it today, is truly an invention built on inventions. It was a combined effort across many decades and experimental prototypes and is a shining example of how science moves forward on the shoulders of previous discovery.

Thomas Edison gets most of the credit for inventing the light bulb, but, in reality, his contribution was mainly to tweak existing inventions to make a commercially viable light bulb. The bulk of the early steps forward to invent the light bulb came from British inventor Joseph Swan, who built upon the work of Warren de la Rue of using metal filaments encased in vacuum tubes. Swan patented his version of the light bulb in early 1879 after almost 30 years of work. 

Edison bought the rights to an 1874 patented light bulb invention by two Canadian scientists, Henry Woodward and Mathew Evans. Their light bulb used electrodes connected with a carbon rod contained in a nitrogen-filled glass cylinder and was by no means ready for mass production. Then Edison, “borrowing” from the Swan’s patented technology, used trial and error to come up with a design that was cheaper to produce and lasted longer, thus becoming a commercially viable product. Edison filed his patent in late 1879 and it was quickly challenged by Swan. Swan won his patent infringement case against Edison, and the court made Swan a partner in Edison’s company. The rest is history.

The light bulb is one of those fascinating inventions we take for granted. A single bulb turns into a multitude of power. The light bulb helps turn darkness into light. (Maybe even too much light when we consider the effects of modern light pollution?)

The light bulb is also associated with ideas, ask any of us who grew up on a steady diet of cartoon entertainment. Many a great accomplishment or a hilarious failure in one of these cartoons grew out of a light bulb appearing above the characters head. 

The light bulb became the basis of one of the classic (and not politically correct) joke cycles of all time, the “How many _____s does it take to change a light bulb?”

For example,

How many scientists does it take to change a light bulb? None. They use them as controls in double blind trials.

How many radio astronomers does it take to change a light bulb? None. They’re not interested in that short wave stuff.

How many software people does it take to screw in a light bulb? None. That’s a hardware problem.

How many hardware folks does it take to change a light bulb? None. They just have marketing portray the dead bulb as a feature.

How many writers does it take to change a light bulb? Never mind that — let me tell you about MY light bulb.

How many lawyers does it take to change a light bulb? How many can you afford?

I know I should apologize for the bad humor, but I find it difficult since I had such a good laugh searching for light bulb jokes. Now, back to the original, and a bit more serious, light bulb theme.

The light bulb of 2025 needs changing. It is yellowed and dim. It’s like the ancient, naked bulb hanging in a dark and damp cellar of a horror movie. Its light creates more shadows and anxieties than it illuminates. It’s high time we change it.

The 2026 assignment is simple. Change the yellowed and dim light bulb of 2025 by shining your light bulb into the creeping darkness and shadows of our times.

  • Shine a light for creativity.
  • Shine a light for books.
  • Shine a light for libraries.
  • Shine a light for bookstores.
  • Shine a light for our schools.
  • Shine a light for STEAM.
  • Shine a light for other human beings.
  • Shine a light for all things we know to be good and to be true!

Above all else, let the bright light of your creativity illuminate everyone you come into contact with. Be inspired by one of my favorite passages from the Bible.

“You are a light of the world. A city set on a hill cannot be hidden. No one lights a candle to be put under a bushel basket; they put it on a lamp stand where it shines for everyone in the house.” (Mt 5:14-15)

In short, SHINE YOUR LIGHT!

One final question.

How many of us does it take to change the dim and sputtering light bulb that’s currently in the socket?

All of us. 

One light at a time. Shining into a multitude of light that drives out the darkness, the shadows, and the fear.

Happy New Year from the STEM Tuesday Team!

Shine on!
