Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

Get things moving with this extensive collection of physical science resources. Covering the fundamentals of measurement, graphing, lab safety, and experimental design as well as the specific scientific concepts...

Students investigate conservation laws using a potato launcher. In this physics lesson, students measure angles, time and distance of the potato. They discuss applications of experiments like this.

Students confirm the law of conservation of matter by weighing chewing gum before and after it is chewed.

Students construct a thermograph for maximum and minimum temperatures for the 2-week period. They illustrate how the earth's atmosphere is heated by convection and conduction currents and evaporation of water.
