ExperimentStates of Matter: Gas All Around Us (Part 3)
What You'll Learn
When matter changes state, its particles move differently. Heating a solid makes particles vibrate faster until they break free and become a liquid, then a gas.
Key Words
- proton
- neutron
Materials Needed
- sugar
- vinegar
- baking soda
- cups
- spoons
- food coloring
Safety First
- Clean up spills immediately to prevent slipping.
- Use materials only as directed in the experiment.
- Keep small objects away from young children.
