Video trouble?

DISCUSS (1 of 3):

What are some of the things you observed?

DISCUSS (2 of 3):

Was there anything that surprised you?

Why did that surprise you?

DISCUSS (3 of 3):

What are two or three questions you have about magnets that no one in your class knows the answer to?

Can you think of experiments that would help answer your questions?

Video trouble?

Demo: Once a paperclip touches a magnet and becomes a magnet itself, does a paperclip STAY that way? Or does it stop being a magnet?

Try it! (Your teacher can demonstrate this.)

Video trouble?

DISCUSS: What do you think you could do with magnets that would be interesting?

There are so many possibilities. Here’s one I like: the magnetic sweeper I used in the parking lot to collect nails and sharp objects so they wouldn’t puncture holes in tires.

Prep Instructions

Set Up Magnet Test Items

The test items should include some metals that are attracted to magnets, some metals that are not, and some non-metal items. At a minimum, students should examine one item from each of these categories. You may want to set up a test item station so that students can explore multiple items from each category.

Cut Up String

Before class, cut up the string so that each student can have some for their experiments.

Teacher Tip

Magnets are fragile, so be careful. If you smack them against each other too hard, they will break. We trust you’ll be gentle with them, but just in case, it can’t hurt to wear safety goggles.
