Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...

After completing the activity, "Kinesthetic Astronomy: The Meaning of a Year," zoom in on Earth's rotation using the same simulation setup and this outline. Each class member dons a map of the Western Hemisphere and plays the part of...

RJ argues that playing the video game, Super Duo Breaker and Whoosh, is a good way to study for a quiz on weathering and erosion. The game character Mr. Breaker breaks things down and the character Mr. Whoosh carries them away in the...

Is it possible to defy gravity? Not really. With force and inertia, we can act against it for a little while, but, eventually, gravitational force will pull us back to Earth. The relationships among mass, force, and inertia are all...

What happens to stars as they get older? A simulation takes pupils through the life cycle of stars based on their masses. The resource introduces the Hertzsprung-Russell diagram and the common relationships and life cycle patterns observed.

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...

Students investigate biology by examining body sizes of different animals. In this antelope measurement lesson, students research the physicality of Antelopes and other large animals that inhabit Earth. Students create a model Antelope...

Tune in! Young scientists use an AM radio at home to monitor solar output. The long-term project would be ideal in a flipped classroom or as an out-of-class project. 

Students brainstorm how they can conserve energy in their daily lives. In this energy lesson plan, students discuss how they use energy and ways to conserve it.
