All that running, climbing and playing kids do puts their muscles to the test even if they don’t realize it. Age-appropriate activities about the muscular system help kids understand how all those muscles work together to control every movement.
Make a life-sized replica of the muscles the kids have inside their bodies. Trace the kids on big pieces of paper to create the body outline. Cut out the bones of the body to glue to the body cutout since the muscles and bones work together. Use pink streamers bunched together to create the muscles. Attach them to the body cutout where they belong in the body. This allows the kids to see that muscles are everywhere.
This science activity shows kids how the muscles work with the bones. You’ll need something to represent the bones — such as toilet paper tubes — and something to represent the muscles — such as long rubber bands or long, skinny balloons.
You need to make a joint with the bone materials. For example, tape two paper towel tubes together so they stay together but still bend. Blow up a long skinny balloon and tie the end. Tape the balloon to the cardboard tube joint model. As the kids bend the joint, the see that the muscle moves with the bones.
Move Your Muscles
Don’t overlook the activities the kids naturally do as a way to teach about the muscular system. Have the kids perform different exercises or physical moves. Have the watch how the body moves as they do the exercises. Discuss how the muscles make the movements possible.
This activity is also a good way to emphasize how important exercise is for muscle function and development. Discuss how exercise strengthens the muscles so you can do more with them.
Flex Your Muscles
With different hands-on activities, kids get a better understanding of what their muscles do for them. With any luck, the activities will spark further questions and exploration opportunities into the muscular system.
