The Human Body:Skeletal System

Skeletal System The skeleton is

made up of all the bones in our body.

It gives our body our shape and protects our vital organs (brain, heart, and lungs)

If you had no skeleton, you would be a blob. �

Demonstration

1. The eggs are going to represent a brain.2. Place 1 egg in container. Seal the lid.3. Jog around the room, shaking the container. What

happened? 4. Now try the same thing with the other egg, but this

time you will add some protection.5. Fill the container to the very tip top with water. 6. Place the egg in the container and seal it closed

with some masking tape. 7. Now jog around the room in the same way as

before. 8. Carefully open the container. What happened

this time?

Write down 2 things you have learned about the skeletal system.

Chicken Wing Experiment To better understand what bones are

made of, we are going to experiment on a chicken bone.

Chicken bones are similar to our own. They are similar enough that we can learn a few things about our own bones!

Can you find this on your chicken wing?
