Properties of Objects and Materials
- Materials can exist in different states -- solid, liquid and gas. Some common materials, such as water, can be changed from one state to another by heating or cooling.
Short Description: In this suite of activities, students investigate ice, learn about its properties and explore how it can change states to a liquid or a gas. Through hands-on experiences, they observe ice, find its melting and freezing point, and learn about some of its unique properties, including that ice, the solid phase of water, is less dense than the liquid!
