Science in a van

Science in a Van


Today at our school we had a science show in our school hall.The scientist Allan and Emily travelled all around New Zealand to teach us all about science.This morning they showed us some optical illusion where Emily used this hypnosis toy where she told us to stare into the middle of it,then she counted to 3 and said to look at her,her head had grown nearly double in size it was called the waterfall effect.The next experiment they showed us about forces using big and small tennis balls.They put the small ball on top of the big ball and they bounce them together to see what happens.It showed us what forces and gravity can do when u combined them together.The person or scientist that came up with forces was Isaac Newton.
