Which objects can a magnet attract and repel?

Required

1

When the magnet attracts and repels the electromagnet, we say the electromagnet has gained ________ energy.

In lesson 3, we watched a video of a teacher testing magnets inside a vacuum chamber. What was the purpose of the investigation? In other words, what did we try to figure out in that investigation?

Required

1

On our driving question board, many students asked, “what would happen to the speaker system's volume if we use more magnets."

If we investigate this question, what would be the cause (the change to the system)?

Ms. Smith found a traditional doorbell the other day. She noticed a magnet stuck on the hammer arm when the doorbell was not connected to a battery.

What could be the reasons that the magnets stuck on the doorbell? You may select multiple.

In order to find out how a doorbell works, Ms. Smith decided to conduct an investigation. To test hammer arm is a permanent magnet, what can she do with the materials available in the science room?

If the hammer arm is a permanent magnet, then when she _______ (the cause), she will observe _______ (the effect).

If the hammer arm is NOT a permanent magnet, then when she _______ (the cause), she will observe _______ (the effect).

Ms. Smith decided to open the doorbell, and she found coils of copper wire. Next to the coils, there is a hammer arm. They are not connected to each other.  In other words, there is space between the hammer arm and the coils.

4

Ms. Smith wasn't sure how the hammer arm was able to hit the bell and make a sound.

Use what we've learned to help Ms. Smith figure out how connecting the battery (cause) causes the doorbell to make a sound (effect). Use words AND digram.

Hint: you only need to draw one coil of wire.

Required

1

What happens to the bell as the hammer strikes it (and after it strikes it) that causes that the bell to produce a sound?

Required

3

In a typical doorbell, the bell that produces the sound is located inside the house. However, the person outside can also hear the bell. How does a person outside the door hear the sound of the bell? How does the sound move between the bell and their ears?

Use words and drawings to explain!
