This is the next set of worksheets in our unit study on the human body. I had started on some of the systems in the body and just wanted to make sure it was finished (Check out the other activities here: Human Body Worksheets). These muscular system worksheets for elementary students are designed to help you teach all about the muscles in your body, at an early elementary level.

What you need to know about muscles
Muscles are fibrous tissues that move your bones and the parts of your body. There are two kinds of muscles: voluntary and involuntary. Involuntary muscles are the ones you don’t have to think about to use.
These include your heart (that pumps your blood all over your body) and your stomach muscles (that help digest your food). Voluntary muscles are the ones that you control directly — like your leg muscles when you walk or your finger muscles when you want to write.
Muscles can only pull, not push. That’s why for every movement you make, it takes at least 2 muscles to do. Muscles are attached to both sides of the bone, through connective tissues called tendons.
When you want to move a muscle, it contracts (gets smaller) and that pulls on the tendon, which then pulls on the bone. The opposite muscle will relax, stretching out. Then to go back, the 2nd muscle will contract while the first relaxes.
Think of muscles like slightly-stretched elastic bands. There’s a certain amount of tension in them that keeps them ready for use. When you move, they pull back on that tension to move your body. If a tendon snaps, your muscle becomes loose and limp. Or if there’s a tear in the muscle, it stops working as well.
Unlike elastic bands, the more you stretch your muscles, the stronger they get. So they have more tension that keeps them ready, and it takes less effort to do the same stretches. And that means then that the same amount of effort can do more things — you can run farther, jump higher, or carry heavier things!
