Frozen Magnets?

Why in the world would you freeze a magnet? For a science project, of course! This week we did a science project for Math and Science Night. Since we studied magnets earlier this year, we decided to use our background knowledge to help us out. Our purpose question was as follows: Will a magnet still work after it is frozen in water? Do you have a prediction? 67% of 2A predicted that yes, the magnet will still attract, and 33% of 2A predicted that no, the magnet will no longer attract. After lots of cold and wet fun, we found out that magnets DO work after they are frozen. Great job 2A scientists!

Tuesday's table checks the measuring cup to make sure they've measured exactly one cup of water.

CJ pours the water into a paper cup.

We put a magnet into the cup of water and then placed it in the freezer overnight.

The next day, we had to peel the paper cups away from our frozen magnets. This was not as easy as it sounds.

Sidnee finally gets the frozen magnet out! Cool!

Monday's table experimented with a round magnet. Looks like the frozen magnet still attracts other magnets.

The frozen magnets even held a chain of paperclips placed end to end.

We had a great time completing our science project, and we'd love for you to get to come see what we did.
Math and Science night is Tuesday, March 24 at 6:00.
Hope to see you there!
