Lesson 1 - The Skeleton

  1. 1. Lesson #1 You Can’t Move Without In a Skeleton! to this lesson, we will begin think and learn about our skeleton and how important it is to us! Created by Mr. Stephen Wentz Council Rock School District
  2. 2. Your Skeleton has Several Jobs • More than 200 bones make up your skeleton • Skeleton helps support your body and stands you upright • Bones are strong like steel beams in a building…they also help us move.
  3. 3. Your Skeleton has Several Jobs • Skeleton helps protect your body. - skull is like a helmet, it protects your brain - bones are like “armor” that help protect your organs • With your group, name three organs, besides your brain, that your skeleton protects… - heart, liver, lungs, pancreas, etc.! • Cool Fact! An adult has about 206 bones…but a baby has as many as 270! - some baby bones actually start out as two or three bones, then they fuse together as they get older.
  4. 4. How Does a Skeleton Move? • Bones are hard and don’t bend • They can only move where they come together… • Joint- the place where two or more bones come together. • Fixed Joint- joints that cannot move, like those in the skull.
  5. 5. How Does a Skeleton Move? • Moveable Joints- joints that move and allow you to move. • Ligaments- stretchy bands that hold your bones in place so you can move.
  6. 6. How Does a Skeleton Move? • There are three different types of moveable joints… • 1. Hinge Joints- allow your arms and legs to swing back and forth • 2. Pivot Joints- allow bones to rotate side to side. -allows your wrist to brush dirt off your pants -allows your neck to rotate side to side and say, “No”. • 3. Ball-and-Socket Joints- allows you to swing your arms and legs in almost any direction. - ex: shoulders and hips
  7. 7. How does the human body respond to physical activity? • We saw… • We felt… • We heard…
