Presentation on theme: "Walk-In Take out notebook, folder, pencil box."— Presentation transcript:

1 Walk-In Take out notebook, folder, pencil box. Copy the question and answer in sentences. Is a battery an example of chemical energy or electrical energy? Explain!

2 Answer A battery is a form of CHEMICAL ENERGY.
It contains acids and other chemicals that take part in chemical reactions. These release electrons, that can flow in a wire as an electric current, which enables a device that runs on batteries to be able to work.

3 Energy Transformations Review

4 1. What energy transformation occurred?
Starting energy Ending energy

5 1. What energy transformation occurred?
Radiant energy Chemical energy

6 Photosynthesis Photosynthesis involves chemical reactions that allow a plant to produce its own food, so a plant’s growth occurs by using CHEMICAL ENERGY.

7 2. What energy transformation occurred?
Starting energy Ending energy

8 2. What energy transformation occurred?
Chemical energy Electrical energy and sound energy
