Level#1

Skeletal muscles are attached to your bones. They are voluntary muscles. You can control when voluntary muscles move. This type of muscle moves your skeleton by pulling on tendons attached to bones.

1. What are bones attached to that allow you to move?

2. What type of muscles can you control so that you can move?

3. How do voluntary muscles work to allow you to move your skeleton?

Level#2

Skeletal muscles are attached to your bones. They are voluntary muscles. You can control when voluntary muscles move. This type of muscle moves your skeleton by pulling on tendons attached to bones. When a muscle moves, it contracts, or shortens. When a muscle relaxes, it lengthens. Muscles can only pull. For this reason, skeletal muscles work in pairs. Most voluntary muscles work in teams of two to move bones.

1. Explain how skeletal muscle allows you to move.

2. Explain what happens when a muscle moves and what happens when it relaxes.

3. Skeletal muscles can only pull. Explain how they move bones?

Level#3

Skeletal muscles are attached to your bones. They are voluntary muscles. You can control when voluntary muscles move. This type of muscle moves your skeleton by pulling on tendons attached to bones. When a muscle moves, it contracts, or shortens. When a muscle relaxes, it lengthens. Muscles can only pull. For this reason, skeletal muscles work in pairs. Most voluntary muscles work in teams of two to move bones. For example, the upper arm has the biceps and triceps muscles. The biceps muscle is the muscle in the front of your upper arm. The triceps muscle is in the back of your upper arm. The two muscles work together when you move your arm.

1. Explain what type of muscles skeletal muscles are, what they can do, and what a muscle does when it moves.

2. Since muscles can only pull, explain how muscles work to move bones and give an example of a pair of muscles that do this.
