Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...

Student learns about the life cycle of plants by watching a time-lapse video. This activity provides pupils with further evidence that all living things grow and change as they progress through their life cycle.

Learners examine the carbon dioxide cycle in the atmosphere. In this element lesson, students discuss the relationship between carbon dioxide on Earth and the plants that store it. Learners play a game to ensure their understanding. 

Students build a model to simulate parts of the water cycle. They recognize and explain the essential elements of the water cycle.

Students illustrate the life cycle of a butterfly. In this life cycle lesson, students use the book From Caterpillar to Butterfly and the Internet to learn about life cycles. Students use different types of pasta to represent the...

In this worksheet on the life cycle of the butterfly, students look at 4 pictures representing the life cycle stages, and choose words from a word box that match each picture. Students then number the pictures in the correct order of...

Students make Moebius strips and use them to demonstrate the interconnectedness of an environment. They explore the natural cycles (water, oxygen/carbon dioxide, carbon, nitrogen) within the environment. They describe how the cycles are...

The most important chemical process on Earth is photosynthesis. Scholars explore the changes in the gases in our atmosphere as life on Earth developed. They create a model of photosynthesis and consider simple questions.

Everyone knows a tree makes a sound when it falls, but what do we know about dying trees? Class members learn background information about Laurel wilt disease from a teacher-led presentation. Team members work with partners to read and...

Three lab guides are given here that detail experiments to illustrate the oxidation of glucose for the production of ATP. The first will compare photosynthesis and respiratio and show theimporatnce of both to plants. The next will show...

Students explore cycles in nature. In this cross curriculum agriculture lesson, students define "cycle" and research weather and planting folklore. Students make a bracelet in which individual colored beads represent the many "cycles" of...

Students examine the rock cycle and the path that rocks go through to rearranged in different ways. They define key vocabulary terms, then in small groups conduct a variety of experiments using crayon shavings as simulated rocks and...

Learners discuss and interpret background knowledge on poster copy given on the water cycle. Students complete the included activity sheets using the poster as a reference in small groups. Learners identify and name where water can be...

Students create a butterfly garden. In this butterfly garden activity, students plot a garden with plant species that will attract butterflies. Students learn about the specific plants and items that will help butterflies use the garden.

Students germinate pea seeds and plant the seeds. They experiment with different amounts of light and darkness on the plant growth.

Students examine different types of movement and causes that may affect those movements. In this online interactive forces and motion lesson, students use toy cars to observe push and pull and then make predictions and collect data...

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

It's a time of change. A hands-on activity engages young scientists in a lesson highlighting the change of seasons. They brainstorm indicators of season changes in nature and then look for them. Next, they record observations in a field...

A Reading Adventure pack explores the busy life of bees. After reading a fiction and nonfiction text, scholars complete three hands-on activities. Participants invent a robot that can do the work of bees, cheers to hardworking bees with...

Young scientists roll up their sleeves and get a little dirty in this three-day earth science investigation. Following the scientific method, children monitor the growth of algae in pond water samples in order to determine...

It's time for a field trip! Scholars take their new-found knowledge of adaptations and seed dispersal on a field trip to a local botanical garden. They gain an up-close look at how ecological interdependence works in a distinct...

The balance of nature can be a wondrous thing! With the 19th lesson of the 21-part series on systems, learners explore the cycle of photosynthesis and cellular respiration using a lab-based activity. Groups set up different test tubes...

One hundred metric tons of CO2 can accumulate in one acre of forest over time—that's a lot of carbon! In the activity, groups of middle school learners determine what makes forests important. They then solidify the concept by using a...

Educate scholars on pollution—air, water, and land—with a series of lessons that begin with a thorough explanation of each type. Learners then take part in three activities to reinforce the importance of reducing pollution. They...
