| Lab Findings | ||
| #1 | We discovered this was an example of a vacuum. | Inside of a light bulb. |
| #2 | This is the piece of metal inside a light bulb. | filament |
| #3 | These are 2 reasons the light bulb would not light. | broken circuit or dead battery |
| #4 | This was created when the battery and light were connected. | circuit |
| #5 | What kind of circuit was created in the lab yesterday? | series circuit |
| Static Electricity | ||
| #1 | Static Electricity is stored energy so it is considered... | potential energy |
| #2 | Two negatively charged balloons would..........when put near each other. | repel |
| #3 | How is static electricity created? | by rubbing two things together or friction |
| #4 | When extra electrons jump onto a balloon, it gains this charge. | negative |
| #5 | Static electricity becomes ...................when it become kinetic energy. | electrical current |
| Electrical Current Issues | ||
| #1 | Pathway for an electric current. | electric circuit |
| #2 | Which direction does electrical current flow? | negative to positive |
| #3 | Its is dangerous to stand in water during a lightning storm because....... | water is a conductor of electical current |
| #4 | When extra electrons jump onto a balloon, it gains this charge. | creating a circuit or breaking a circuit |
