Create a model of the atoms of a substance moving through the solid, liquid, and gas states. This can be a physical model using household or crafting items or a colorful diagram, illustration, or animation. You can be as creative as you want. Be sure to include and label the following items in your model:

the three states of matter
movement and spacing of molecules
loss or gain of kinetic energy and temperature
transfer of heat
breaking or building of intermolecular bonds
Include one paragraph to explain the movement of energy during phase transitions. View this student example using candy to help spark your own modeling ideas.
