Bones

Without bones, you would not be able to stand. Your skin would fall down, and you could not walk or run. We need our bones!
A baby who has just been born has 300 bones. Slowly, these bones grow and join together. It is important to get plenty of calcium in milk, cheese, and yogurt. Calcium helps your bones to grow strong.
Adults have 206 bones. By the time they are 25 years old, all bones have finished growing. Now, you have a strong skeleton!
Take good care of your bones. For example, wear a helmet when you ride a bike or skate. This will protect your skull. Wear knee pads and elbow pads, too. A broken bone hurts, and it takes a long time to heal. Treat your bones nicely, and they will be nice to you!
