A fifth grade student studied many hours for their electricity test. After they received their grade on their test, they realized their grade had improved and the studying had paid off! What is the dependent variable in this scenario or question? |
The test score |
| The basics of Electricity |
| #1 |
What is electricity? |
the flow of electrons |
| #2 |
What are the three components that make up an atom? |
protons, neutrons, and electrons |
| #3 |
Where are the electrons located on an atom? |
the electrons orbit around the nucleus of an atom |
| #4 |
List the three types of energies that electrical energy can be transformed (changed) in to? |
Thermal energy (heat energy), radiant energy (light energy), mechanical energy (potential and kinetic energy) |
| #5 |
If I hold a ball ten feet high and my sister holds a ball seven feet high, which ball has greater potential energy? |
My ball. The higher an object is raised, the greater its potential (stored) energy will be |
| Static Electricity |
| #1 |
Who discovered electricity? |
Benjamin Franklin |
| #2 |
A negative charge and a negative charge will -? |
repel. (Example: two balloons rubbed against hair) |
| #3 |
Fill in the blank: Static electricity is the electric charge that is caused by _________ or moving electrons. |
friction |
| #4 |
Is static electricity natural or created? Justify your answer by using an example/s. |
Both. Nature=lightning. Created= Many examples (rubbing balloon on hair/head) |
| #5 |
When lightning occurs, what is happening in the cloud? |
A charge separation. Negative (heavier) charges fall to the bottom of the cloud and the positive charges rise to the top of the cloud) |
| Circuits |
| #1 |
Who invented the light bulb? |
Thomas Edison |
| #2 |
If I turn the lights off in this room, the electrical circuit could be described as a/an- |
Open circuit |
| #3 |
What type of circuit am I describing if I remove one light bulb from my circuit and the rest stay lit? |
Parallel |
| #4 |
List one example of a conductor and insulator |
Conductor=copper wire, penny, paper clip. Insulator= rubber, plastic, paper, wood |
| #5 |
Where would I find an example of a series and a parallel circuit in real life? |
Series=christmas lights. Parallel=house |
| Magnetism |
| #1 |
What two things did Michael Faraday invent? |
electromagnet and electric motor |
| #2 |
The opposite poles of a magnet will -? |
attract |
| #3 |
What are three items that can be picked up using a magnet? |
paper clips, iron filings, metal clips |
| #4 |
What is the needle of a compass made of? |
a permanent magnet |
| #5 |
If I wrap a copper wire around a nail and attach the ends of the wire to a battery I can create an electromagnet. How could I make the electromagnet stronger? |
By increasing the number of coils (copper wire) |
