We had great fun experimenting with magnets. We found lots of things around the class that attract magnets. We learned that magnets have two sides. We learned opposites attract and same sides repel. We had lots of fun repelling and attracting. It looked just like magic when teacher put the same side of the magnets together, the magnet spun around without anything touching it!

We learned some really interesting things from the mad scientist who visited our school. We thought he was a bit like a magician. We learned alot about something that is all around us but which is invisible. Some very clever children knew the answer, air! We learned how to make a ping pong ball float. The airflow from the hair dryer pushes the ping pong ball upwards until its upward force equals the force of gravity pushing down on it. We learned about hover crafts and one lucky boy had a turn on a hover craft. We learned all about air and if we suck air out of objects we can create a vacuum. A vacuum makes it impossible to pull objects away from each other. We learned the power of little objects when placed correctly. They can take a lot of weight when it's distributed evenly.
