Muscles and Pinocchio’s Arm

Get involved in exploring various parts of the human body with engaging, interactive science activities. It’s all about doing and actively participating in your own learning. The time is now, so get started and see where it takes you.

Explore the functions and purposes of muscles in the human body. Using materials such as pieces of wood, springs, string, or rubber bands, try your hand at constructing one of Pinocchio’s arms to discover how muscles work at a joint and how they also work in pairs.

• Learn how muscles are the structures that produce movement in the skeletal system.
• Construct Pinocchio’s right arm using everyday materials.
• Figure out which materials represent the bones of a real arm and the fluid between the skeletal joints.
• Understand why muscles frequently work in pairs.
• Watch an animation showing how muscles work in pairs.

App features:
• Participate in a hands-on activity about the movement of the skeletal system.
• Consider how some everyday objects relate to the structures and functions of the human body.
• Receive helpful hints and answer questions as you carry out the activity.
• Demonstrate what you learn by taking quizzes.
