Radiation has numerous real-world applications, some of which are relatively safe while others can be extremely hazardous. In this nuclear chemistry project, young scientists choose a practical use of nuclear reactions to...

Seventh graders discuss how energy is transformed from one form to another. In this physics lesson, 7th graders design and build their own hydro generator. They identify the factors that affect its energy production.

Seventh graders research on energy conversion. After they have researched several types of energy resources, teams of two to four create posters which depict how these resources can be conserved.

Students are assigned to groups, and determine each member's role in the group. They will design an experiment to determine a way to produce the three primary and five secondary colors. Students discuss color and mood. They listen to a...
