Students complete an experiment using balloons to help them examine the concept of static electricity. They discover how engineers use this information to create better air filters for homes. They describe how to charge an insulator as...

Students work together to create rockets on a budget. They discover the limitations that real engineers face when designing and testing their products. They discuss their findings to complete the lesson.

Students design and build a tractor using LEGO materials. They write and draw their designs.

Students record weather observations and research online weather data. In this weather observations lesson, students study the cloud cover for several days and record their observations in a chart. Students identify the cloud types and...

Learners predict and examine the direction seeds grow and thereby explore the effects gravity has on seeds and plants. They perform this inquiry in-class by keeping track of how beans grow.

Students define adaptation and highlight example of adaptation in birds and other animals. They study feeding techniques of seabirds and investigate the effect that trash has on wildlife.

Students determine the appropriate clothing for warm and cold weather. In this weather and clothing lesson, students draw and describe appropriate clothing for cold and warm weather.

Students apply knowledge of underwater ocean life by creating an ocean life scene with marine animals and plants placed at appropriate ocean depths.

Students investigate the formation of rain. They experiment by boiling water in a tea kettle and placing ice cubes and water in a pan. They hold the pan of water over the steaming spout so that the steam strikes the bottom and sides of...

Students reflect on the data they have analyzed during the Global Sun Temperature Project. They use the project website as a resource for their observations, draft a class report and post it on the Internet.

Students read a poem about a cat. Students discuss how cats behave and examine Homer's life in his environment.

Third graders identify a cloud and explore how they form. They create an acrostic poem about clouds.

Students examine the components and relationships of ecoregions and ecosystem management. They define ecoregion and ecosystem, list ecoregions, and participate in a simulation that demonstrates the connections between parts of the...

Third graders discover the concept of ride sharing. They discuss how it helps the environment. They use the internet to gather information as well.

Students examine axles and wheels using LEGO materials. They investigate the uses of axles, gears, and wheels.

Students study how animals need water, food, shelter, and space to survive. They also study what animals need to survive in the winter. They play the part of animals and winter "threats" in a game of tag to reinforce concepts.
