Today's Classroom Activities :

How Our Muscles Work

Muscle Power
Science Stretch and release a rubber band. Ask students to contribute ideas about what part of our bodies acts like a rubber band. Students can feel their muscles by placing their hands on their cheeks and alternately smiling and frowning or by placing their hand on their calf muscles and pointing their toes. What other muscles can they tighten and relax? What jobs do muscles help our bodies do? How can kids use the rubber band and objects around the room to explain how muscles work?

Muscles in Motion
