Simulate how bones, muscles, and joints in the human body work to transfer energy to objects, making them move.

Demonstrate that energy of motion can be transferred from one object to another (e.g., moving air transfers energy to make a pinwheel spin). Give examples of energy transfer from one object to another.

Identify that the energy of a moving object depends upon its speed. Give examples of how an object’s energy of motion increases when the object’s speed increases.

Describe how energy can be stored in an elastic object or material by stretching it. Use diagrams to describe ways that the energy stored in a stretched object can be used to make objects move.

Identify that objects that move have energy because of their motion. Demonstrate that a hanging mobile has energy because of its motion and the mobile was given this energy by the push of moving air.
