The Mad Scientist in Stonebridge

Today is a special day because a mad scientist was in the school. The mad scientist taught us about a famous scientist named Sir Isaac Newton. First she taught us about forces for example: inertia, pushes, pulls, contact, non-contact and the north and south poles of a magnet. The mad scientist gave us a bottle of iron hair and sand. When we used a magnet and put it on the side of the container and moved it up, the iron hair followed the magnet by how it is moving. I wanted to tell you the next part was weird. First she set up a car and put a soldier on the back of the car. Then, she set up a brick [she pretended the brick was a wall] and she pulled the car forward and backwards until it was fast enough and the car hit the brick. The soldier flew forwards. She wanted to show the force of inertia. It was so funny.


Then, the mad scientist told us that the class had to do an experiment. The mad scientist split us into groups of fours. She gave every group a race car, sand paper, wax paper and a white board. The mad scientist said we put a brick under the sand paper. We put the wax paper on top of the sand paper. We put the toy car on top of the ramp and on top of the wax paper and let go. We recorded the answers using tape. She wanted to show us which surface has the most friction and least friction. The result was the sand paper has the most friction.

Next, she taught us to do another experiment. The first step was to make a ball of clay. The mad scientist gave each of us two beads, a thick straw, a thin straw, tape, and a piece of foam. She told us to put the thick straw in the clay. I folded the thin straw in half and put the beads almost halfway in the straw. We taped the thin straw with bead to the piece of foam. Then, we scrubbed the foam on the carpet to make electricity. We put the thin straw in the thick straw. Then, we moved our finger around the foam. It moved and followed our finger. The electricity made the foam move. The mad scientist gave each of us a word search. We worked until recess. When we came back in, we made a fake rattlesnake to scare mom. At lunch Aeon and I took our rattlesnakes outside. Aeon scared 7 people with the rattlesnake. I scared 11 people with my rattlesnake. I had a great science day. I felt excited.
