Heat up some interest in solar energy. Young engineers create a water heater that runs on solar power (simulated by a lamp). Using thermometers, they determine the change in temperature before and after the water goes through the heater.

Adjust the melting time of ice without varying the temperature! Learners experiment with different materials to decide how the materials affect the rate an ice cube melts. They then connect their findings to the conductivity of each...

What is biogas and how is it made? After examining background information about the sources of biogas and biogas generators, class members follow the provided information and build a biogas generator that can be used in the...

An Internet project designed to determine the greatest influence on the boiling point. After reading the project instructions and performing the experiment, submit your data and compare your results to other classes from around the world.

Provides information about the distinction between heat and temperature, and allows you to check your understanding through exercises. The Kelvin, Fahrenheit, and Celsius temperatures are compared and discussed.
