Standard 2/Middle School/Benchmark 4
Benchmark Question: How are common energy
transformations used in everyday situations?
Focus Question: What kinds of energy transfers occur
in various toys?
Before beginning the explorations,
students should be familiar with energy and its forms (see Key Concepts).
Also, the teacher should discuss everyday examples of energy
transformations (burning coal to produce electricity, digestion of food,
speakers, photosynthesis, etc.).
The teacher will give each
small group a toy that undergoes one or more energy transfers (See Toy
Examples below). Groups will investigate the mechanics of their toy and
identify its energy transfers. Groups will demonstrate and explain how the
types of energy change in their toy.
Toy Examples: tops, music boxes,
Jack-in-the-Boxes, wind-up toys, push and pull toys, string-pull toys, and
