change of state (physics)

Describes the properties of the different forms of matter and explains how each form of matter can be changed into the others.

Presents twenty-four toy-based activities for use in middle-school classrooms that teach science lessons about matter and the changes it can undergo, providing opportunities for students to explore matter in its three states--solid, liquid, and gas.

Contains examples and experiments that provide information about matter and help readers better understand the concepts related to it.

Explains the science of solids, liquids, and gases, discussing what they are, and looking at their various properties and characteristics. Includes a glossary.

Explains the basic properties of matter through looking at everyday experiences and direct observation.

Explores the science concept of states of matter, how different states exist in everyday situations, and how this concept is used in technology.

A simple presentation of how homes are heated, how to use less energy to heat a house, and where that energy comes from.

An exploration of heating and cooling that covers temperature, changes of state, conduction, convection, heat radiation, and storing and saving heat.
