The materials that an electric current can flow through are called?

conductors

The materials that an electric current cannot flow through are called?

insulators

Why were our wires coated with plastic? Was this an insulator or a conductor?

They were coated with plastic so we would not get shocked. The plastic was an insulator.

The metal part of a light bulb.

conductor

Larry was struck by lightning. The current traveled from the top of his head to his big toe. Did his body act as an insulator or conductor?

conductor

Name 3 ways that we use electricity.

Answers will vary

Describe how we got our light bulbs to light up.

Answers will vary

Carly made an electromagnet, but it wouldn’t pick up her staples. What can she do to make it stronger?

Bubba made a circuit, but his bulb wouldn’t light up. What does he need to do to fix his problem?

Check all of the connections (is the circuit closed).

Are his batteries turned the correct way with opposite poles touching?

Is the bulb burned out?

Is the battery dead?

Tell three electricity safety rules.

Answers will vary

In a scientific experiment, after asking the question you form a __________?

hypothesis

We tested the temperature of fresh and salty water. What did we do to insure a fair test?

Everyone had the same amount of materials. We did the experiment several times.

After the experiment is finished, we need to write a __________.

conclusion

Marly wants to test 3 different brands of laundry detergent. Her hypothesis is that brand M & M will get her clothes the cleanest. What does she need to do to test her hypothesis?

Test different detergents in the same amount and temperature of water.

Pedro walked into his kitchen and saw water all over the floor. The sink was full of water, soap, and dirty dishes. What is an inference that he can make?

Answers will vary

What can you use to turn a circuit on and off?

switch

What does this symbol represent?

bulb

What symbols are on a battery? What do they tell you?

Use these symbols to draw a circuit.

The wires should be connected to each end of the battery and to either side of the bulb.

Answer

The batteries need to be + - + -

A path for electricity to travel/flow through
