Unit 7.1 Lesson 08: Magnetism & Static Electricity

Two magnets are held close together, as shown below.
Draw arrows to predict the direction the magnets would move once released. (Use two arrows, one for each magnet.)

The interactions of these magnets is an example of a cause-and-effect relationship. What would cause the magnets to behave this way?
(Write at least one complete sentence.)

These two magnets with unlabeled poles are held close together, as shown below.
Label the poles of each magnet to indicate the arrangement the magnets need to have to cause the magnets to attract one another once they are released. (Label one “N” for North and one “S” for South in the gray boxes for each magnet.)

Steve and Joey each gave a balloon an electric charge by rubbing it on their heads.  Steve rubbed his balloon against his hair for 15 seconds.  Joey rubbed his balloon against his hair for 45 seconds. Then, they each held their balloon 10 cm from their head.

Whose hair will stand up more from the charged balloon, Steve or Joey?

What would cause his hair to stand up more from the charged balloon than your other friend? (Write at least one complete sentence.)

Steve wants to find out if the distance at which he holds a balloon away from his hair has an effect on the amount of hair on his head that is attracted to the balloon.  First, he rubs a balloon against his hair for 30 seconds and then holds the balloon five centimeters from his head, looks in a mirror, and records his observations. Then, he rubs the balloon against his head for 30 seconds and then holds the balloon fifteen centimeters from his head, looks in a mirror, and records his observations.

Predict which distance the balloon was held from Steve’s hair will cause more hair to be attracted to the balloon.

What scientific ideas about static electricity could you use to support your prediction?
(Explain WHY your prediction is correct.)

One of the heavy bolts that holds the door on your locker fell off.  The bolt landed in a crack between the lockers that cannot be reached by hand. The custodian suggested attaching a magnet to a meter stick and using that to retrieve the bolt. He can go to the store to buy a magnet, but has a small budget. He has asked you to decide which of three magnets he should purchase and use to get the bolt:
Magnet A would cost $15
Magnet B would cost $5
Magnet C would cost $10.
The bolt weighs 18 grams.  In order to decide which magnet to use, you conduct some experiments to determine how many nails each magnet can lift. Each nail weighs 1 gram. The data table from your experiment is shown below.


Complete a Claim - Evidence - Reasoning exercise to determine which magnet should be used to retrieve the bolt from the crack, while being aware of the custodian’s budget.

Claim: Magnet ______should be used to retrieve the bolt. (Write “A”, “B”, or “C” in the space provided to make your selection.)

Evidence: Use data from the table as well as what you have learned from the lesson to provide evidence that supports your claim for which magnet should be used.
(Write at least two complete sentences.)

Reasoning: Now that you’ve stated your claim, and provided evidence to support your claim, you need to tie everything together by explaining your reasoning. (Write at least two complete sentences.)
