Explore Atoms and Molecules

Learn about different states of matter and how atoms and molecules react to temperature.

1. Change It!:

2. States of Matter (e-Learning for Kids):

3. Gases Around Us (BBC):

Listen to and follow the directions on the screen.
Heat and cool the liquids in the beakers and complete the experiment.
Click on the Sorter button and drag the pictures to the boxes for solids, liquids and gases.
Take the quiz to see how much you know about solids, liquids, and gases.
Only move on to these two activities if instructed so by your teacher.

4. Zooming in on Matter (Harcourt):

Follow along as the information is read aloud and click the arrows at the bottom to move from page to page.

5. States of Matter: Basics (PhET):

Pick an atom (neon or argon) and heat the container by pushing the heat button up.
Watch and describe what happens as the container heats up.
Cool the container moving the heat button to cool. Watch and describe what happens to the atoms in the container.
Add molecules of water to the container. Heat and then cool the water. Describe what happens to the water molecules.
Click on the Phase Changer button. Heat the atoms and describe what happens to the atoms in the container.
Put molecules of water into the container and heat it. Describe how the pressure changes.
