Changes Caused by Heating and Cooling
Students will compare changes in materials caused by heating and cooling.
The student knows that matter has physical properties and those properties determine how it is described, classified, changed, and used.
Changing States of Matter: CHEM4Kids (website) – Clear concise description of how all matter can move from one state to another.
Water and Ice: Science NetLinks (website) - Students explore what happens to water as it changes from solid to liquid and back again.
Melting and Freezing: Science NetLinks (website) - Students explore what happens to different substances as they change from a solid to a liquid or a liquid to a solid.
