Here is a letter I have used in the past.
Make Your Own Flashlight
To show a
thorough understanding of how to make a complete circuit, build a homemade
flashlight.
To help in
the process, answer the following questions
1.
What are the necessary parts to make a complete
circuit?
3.
What are some materials you have at home that could be
used as conductors?
Now let’s build.
1. Take apart a
flashlight.
2. Identify which parts are conductors and insulators.
3. Examine how it works.
4. Illustrate and label the parts.
5. Build a flashlight using a light bulb and materials
you have at home.
Have fun and get as creative as you want to.
