Bones and Muscles

A Today you'll learn

Understand that bones form the skeleton inside our body
Understand how muscles help bones move
Describe ways to keep bones and muscles healthy

B Let's understand

Our body has many bones joined together, forming the skeleton. The skeleton gives our body its shape and protects important parts inside, like the brain and heart. Muscles are attached to bones, and when muscles pull on bones, our body parts move. Eating healthy food, drinking milk, and playing outside help keep bones and muscles strong.
