| A | B |
|---|
| an energy form | electricity |
| what kind of circuit provides a complete path for electricity | closed |
| what kind of circuit does not provide a complete path for electricity | open |
| What are the two special spots that need to be touched for a bulb to light | battery and bulb |
| In order to make a bulb burn brighter what could you do | add dry cells |
| Christmas tree lights are an example of what kind of circuit | series |
| Christmas tree lights are series circuits, because | if one goes out they all go out |
| nonconductors of electricity | insulators |
| 5 examples of insulators | rubber, styrofoam, plastic, cloth, and wood |
| things that conduct electricity well | metals |
| the wires inside a lightbulb are called | filaments |
| all matter is made up of | atoms |
| atoms are made up of negative | electrons |
| atoms are made up of positive | protrons |
| atoms are made up of neutral | neutrons |
| the part of an atom that moves around and causes you to get shocked during static electricity | electrons |
| The reason you get shocked when you walk across a carpet on a cool, dry day | electrons transfer |
| the ends of magnets are called | north and south poles |
| you can tell where the poles of a magnet are by | finding which end iron filings are attracted, they are the most powerful |
| two circle magnets on a pencil will | repel each other or the poles will push away |
| how do you make a temporary magnet | rub iron, nickel, or cobalt against a real magnet |
| what two things does an electomagnet combine | electricity and magnetism |
| how can an electomagnet lose its magnetism | breaks the circuit |
| 5 things in the room that are magnetic | board, cabinet, chalk tray, door frame, candle lid |
| which metals are magnetic | nickel, cobalt and iron |
| What safety rule would you use to prevent a baby from getting a shock from an outlet | use covers |
| What safety rule would you use to prevent shock when working on a toaster | unplug all electrical appliances before working on them |
| If you connect a lightbulb sitting upon a postive end of a battery and the negative end of a battery with a wire will it light? | yes |
| If a lightbulb is sitting on a postive end of a battery and you connect the negative and postive ends of the battery will it light | no |
| If a lightbulb is lying on its side on the negative end of a battery and you connect the end of the bulb and the postive end will it light? | yes |
| If a lightbulb is lying on its side on the positive end of a battery and you connect the side of the bulb with the negative end of the battery will it light? | no |
| If a lightbulb is on the side of a battery and you connect it to the positive end of the battery will it light? | no |
| If you connect the positive and negative ends of a battery and the lightbulb is touching the middle of the wire will it light? | no |
| If you connect the positive end of a battery and the end of a lightbulb will it light? | no |
| If you connect the negative end of a battery with the metal side of a lightbulb which is setting near the positive end but not directly on the positve poleof a battery will it light? | yes |
| If a lightbulb is sitting on the negative end of a battery and you connect the metal side of the bulb and the positive end will it light? | yes |
| What metal is not magnetic? | copper |
| What part of a magnet has the greatest attraction? | poles |
| Like poles | repel each other |
| Unlike poles | attract each other |
| What is a cow magnet used for | Farmers have the cow swallow the magnet so that anything metal eaten by the cow would be attracted by the magnet |
