Group Activity

Have two members of your group put on their roller skates (or ice skates, if possible). Have the two skaters stand close together facing each other. Have one skater firmly but not violently push the other skater away. Note what happens to the two skaters and compare the results with the prediction of Newton's third law of motion. If possible, do the experiment with two skaters of about equal size and again with two skaters of very different sizes.
