We will be studying safety and how important it is to follow rules and procedures during science class. Our first experiments involved static electricity and how it effects all of us. This week we will be working with magnets each one has a positive and negative pole. Opposite poles are attracted to each other, while the same poles repel each other. The strongest magnet is made of Neodymium which is an alloy made from iron and boron.

Have you ever had an MRI our students will be able to tell you why they are all about large magnets. They can produce detailed images of almost every internal structure in the human body.
