Make sure your house is warm in the winter. Pupils analyze graphs of heating costs for two similar houses and make hypotheses for why the costs differ. They then build models of houses with appropriate insulation to reduce heating costs.

Learners test insulation materials. In this energy conservation lesson, students use different insulation materials to see which one holds heat the best. Learners pour hot water into bottles, take the temperature, wait 15 minutes, then...

Students build conductivity testers and investigate which solids and solutions conduct electricity. Working in groups, they predict which items will conduct electricity and record their answers on worksheets.

Middle schoolers redesign their school to make it more energy efficient, and create a model of their design. Learners get together in groups of 5, and they take on the task of making their school more energy efficient. To do this, they...

A solid foundation is important for all things—especially houses. Learners research different materials for foundations based on environmental impact and cost. They decide whether concrete, insulated concrete, or wood would be best for...

Third graders review the effects of gravity on how objects move. In groups, they design a roller coaster and share it with their classmates. Using materials given to them, they build their roller coaster and let a ball roll on the...
