Learn about kitchen chemistry alongside Ruff Ruffman in this Teacher's Guide from The Ruff Ruffman Show. Heating or cooling a substance may cause changes that can be observed, and sometimes these changes are reversible and sometimes not. Different kinds of matter can be solid or liquid depending on temperature. Students can use the videos, games, and activities from The Ruff Ruffman Show to discover how by investigating solids and liquids and exploring heating and cooling, science can help you become a better cook!
