Prior Knowledge Questions (Do these BEFORE using the Gizmo.)
1. When you lift a weight, what part of the arm is doing the most work?
The muscles in the arm like the bicep and tricep.
2. How do you think your arm muscles cause your forearm bones to move?
When the arm muscles contract, the forearm bones react by moving
toward the upper arm.
Gizmo Warm-up
In the Muscles and Bones Gizmo, you will learn about the anatomy of the
arm. You will build an arm model, then test its ability to lift a dumbbell and
throw a ball. You will see how making adjustments to the arm can affect
its ability to lift and throw.
To begin, make sure you are on the ANATOMY tab, the entire arm is
shown, and no circles are open. Select Hide muscles. Click Play.
1. Describe what the arm bones are doing.
The arm bones are moving closer together as they contract.
2. Turn off Hide muscles and turn on Show labels. Describe what the biceps and triceps are doing as the
forearm moves up and down.
