This activity has students/participants act as particles. To start, participants are given baseline information about how attractive forces between particles can vary from very strong to negligible, & that particles are always in motion. To model very strong forces participants link arms at the elbow, for moderately strong forces they hold hands, & for weak/negligible forces they can only hold each other’s pinky fingers. Participants start far apart & move very slowly to model a very cold temperature. At this speed, all of the participants are able to form an organized structure (solid). With each iteration the participants move faster. This results in the weak force group not being able to form structure (gas), the moderate force group being clumped together but not organized (liquid), & the strong force group still being able to form an organized structure (solid). Activity will then be modified to explain WHY gas law variables have the relationships they do (P,V,T, n).

TAKEAWAYS:
Students will not only know the properties of solids, liquids, and gasses, but will also be able to give in-depth explanations as to WHY the properties are different by behaving as the particles at different temperatures and with different attractive forces.
