An introduction to Matter

2. Key Vocabulary Matter Mass Volume The Law of Conservation of Matter *Write these in your Science Journal now. We will define them throughout the lesson.

3. Matter Matter, matter everywhere. There’s matter in your hair. Matter in the air. There’s even matter in a pear! There’s liquid matter, solid matter, and matter that’s a gas. Even YOU are matter, because you have volume and mass!

8. Matter and Mass Matter- Anything that has mass and takes up space. (ex: Solids, Liquids, Gases) Mass- How much matter it takes to make the item. *Remember my pen example

9. Volume What is VOLUME? Volume- How much space the item takes up. Write a definition for VOLUME in your Science Journal.
