We were learning about Inertia, part of Newton's first law of motion. This law basically means when an object is at rest it doesn't want to move and when the object is moving it does not want to stop. The equipment we used was: 1 cup, Water, A flat tray or plate, 1 egg and 1 cardboard toilet roll.
What we did was fill the cup with water then place the plate on top, then balance the toilet roll on it's end on the plate. We then put the egg on the toilet roll length ways and tried to hit the plate out from under it so that the egg fell into the cup of water.
The science behind this experiment was about, Newton's First Law, once the egg was moving, it didn't want to stop. The container of water interrupted the egg's fall, providing a safe place for the egg to stop moving so you could recover it unbroken. The gravity-pushed egg caused the water to splash out.
I found it easy to hit the plate and toilet roll out from underneath the egg because all you had to do was give the the plate a short sharp tap and it shot out from under the egg. My partner Olivia gave both our eggs little cracks then later on I enlarged them, causing the yolk and egg whites to spill out. Nothing was really hard to do.
Next time I will not hesitate before I hit the plate because the times I did that the egg broke and created a rather large mess evolving a lot of water and some egg whites and yolks.
