Explore the states of matter by heating, cooling, and compressing atoms and molecules. Watch as solids melt, liquids boil, and gases condense while you learn how temperature and pressure affect particles.

Discover how light interacts with molecules in our atmosphere! Explore how different types of light, from microwaves to ultraviolet, cause molecules to move and absorb energy.

Test your knowledge of solids, liquids, gases, and plasmas in Matter Sorter! Quickly sort falling objects into the right bins before time runs out, and learn about the fascinating world of plasmas along the way.

Mix chemicals with water and watch the solution change color as its concentration increases. Experiment with volume and solute to see how concentrated you can make your solution before it becomes saturated!

Explore atomic bonds. Change states of matter by adjusting temperature and pressure in this simulation that demonstrates how atoms move and bond.

When the kids find a crystal cave under the Yard, they learn all about crystal molecules and dig up some sweet crystals for their collection in the museum.
