Melting Ice is Hot Stuff!

Fourth graders predict what happens in a teacher demonstration of a chemical change, before watching it. They observe the demonstration and list what the see on the board before determining which represent chemical change. Working at...

Learners investigate solar energy. In this solar energy lesson, students compare how heat is absorbed in light-colored objects and dark-colored objects by making S'mores.

Students see that solar energy is the energy given off by the sun. They explain that when light energy is absorbed by objects it is changed to heat energy and that dark-colored objects absorb more light and store more heat from sunlight.

Students use the energy of the sun to make s'mores. In this solar energy lesson, students gather the listed materials and follow the procedures to find out if they can make s'mores using solar energy.

Students cook with the power of the sun. In this solar energy lesson plan, students explore solar cooking as they apply scientific principles to cook s'mores.

Students investigate the greenhouse effect. In this environmental lesson, students investigate why the greenhouse effect changes the climate through an experiment. Students use vinegar to simulate how acid damages the environment.
