Let’s see how much you’ve picked up with these experiments and the reading – answer as best as you can. (No peeking at the answers until you’re done!) Just relax and see what jumps to mind when you read the question. You can also print these out and jot down your answers in your science notebook.

1. Draw how you can connect a buzzer, LED, battery pack, and motor together AND have them all work at the same time.
2. How can you make a motor (that’s already wired up in your circuit) go faster?
3. What does a DPDT switch do? Draw six dots (like the six on a die) – these are the six terminals on your DPDT switch. Using your diagram, draw how you would connect the DPDT switch so that it can turn the motor on and off, as well as reversing it.
4. Can you use the same electrical circuit for the underwater robot as the laser light show? Why/why not?
5. Why does the pressure sensor work?
6. What kind of switch is the trip wire?
7. Name three ways you would improve the Jigglebot Robot.
