Science

Homeschool science has been interesting for us! The girls have been working in a High School Physical Science text with some other children. It has been a bit dry! So, last week we got out some science tools ordered from HomeScience Tools and did some experiments!

Here's what we learned:

1) Lentz' Law says that the changing of a magnetic field as it drops through a copper tube induces circular electric currents int he tube that push against the falling magnet and repel it, causing it to fall slowly.

2) Magnets are surrounded by a magnetic field that spans in all directions. This magnetic field is strong enough to support a paper clip tied to the end of a piece of string.

3) A magnetic field is so strong that it can defy gravity. A leaning magnet at the right distance from another magnet will not fall.

4) US Currency has small amounts of iron added to the ink and a very strong magnet can move a bill.

5) A magnetic field curves around a magnet in the shape of an oval. We discovered this by playing with metal shavings, a piece of paper, and a magnet.
