Equilibrium - "Hungry Hungry Hippos" style

Today we did an activity where we modeled a reversible reaction achieving equilibrium in a "closed" system. One person was the agitator representing the kinetic energy of the molecules, one person represented the "forward reaction" by putting together the beads into pairs, while another person represented the "reverse reaction" by trying to take apart the pairs at the same time! We had a great and noisy time while experiencing equilibrium at the particle level. This was a truly hands-on experience!
