Physical Activity 3 of 4 Teaching Steps 1. Ask students to raise their hands if they know what muscles are. Have a few students volunteer their answers. Have each student make a movement-any movement.
Muscles allow the smallest move, such as a twitch of the finger, or big movements, such as tumbling.
Demonstrate the importance of warming up. Pass around three of the rolls of frozen cookie dough. Ask students to try to bend the roll of cookie dough. The frozen cookie dough is hard to bend, because it is stiff and cold. Muscles that are not warmed up are also stiff and cold.
