Many materials expand when heated and contract when cooled. What do you think will happen to the elasticity (stretchiness) of a rubber band when it is heated or cooled to various temperatures?

[Free Registration/Login may be required to access all resource tools.] Using the law of conservation of energy as a starting off point, students use the specific heat equation to perform calculations that relate mass, specific heat,...

In this activity, students will investigate whether the temperature of water affects its density. Students will place colored hot and cold water in a cup of room-temperature water to see that cold water sinks while hot water floats. Then...

Students relate thermal energy to heat capacity by comparing the heat capacities of different materials and graphing the change in temperature over time for a specific material. Students learn why heat capacity is an important property...

This viewer allows you to see ocean heat storage from space. These images indicate sea surface heights. Learn more about El Nino and La Nina and how they have profound effects on world climate.

A collection of video lectures from a general chemistry class for high school students. Lectures cover topics such as equilibrium, thermochemistry, electrochemistry, and acids and bases with forty-four lectures. Lectures vary in length...

Determine how the starting temperature affects crystal growth and heat generation of a hand warmer in this chemistry science fair project. The Science Buddies project ideas are set up consistently beginning with an abstract, objective,...
