Solids, liquids, and gases contain the same-sized particles with different amounts of energy: heating makes particles move faster and more freely, while cooling makes them slow down and lock closer together.

What your child will figure out
- Compare the arrangement and motion of particles in solids, liquids, and gases.
- Predict a state change before adding or removing heat.
- Explain melting, condensing, and freezing using changes in particle energy and motion.
- Transfer the particle-energy rule to an unfamiliar substance and a reverse state change.
The levels
- Particle decoder
Compare solid, liquid, and gas particle patterns and connect freer motion with more energy.
- Heat a solid
Predict and observe a solid melting when heat adds particle energy.
- Cooling chain
Predict gas to liquid to solid as energy is removed in two steps.
- Mystery transfer
Apply the same energy rule to cool fictional Nova mist from gas to solid.
