What's better than some photos of what we did?
This experiment was a favourite for most of the boys! You pull the lever up, then press it down with as much force as you can. The gas from the air goes through the pipes, and then pushes a ball up into the air! We tried to shoot the ball really high.
This is Lorenzo testing his reaction times. He had to press a button when the red light crossed directly over the red light.
There was a metal detector that we could use to find solid things made of metal. Here is Manshika pulling a heavy chain up and down over a wheel.
Here is Jay doing is fingerprints by dipping them into an ink pad then pressing them onto paper. Everyones fingerprints looks different. This is Manaia testing which materials are magnetic and which aren't.
Ali Komial is generating power to turn the blue light on by winding the handle. He was using all his strength to make the handle wind really fast!
Fiona is checking out how the matter inside a solid, liquid and gas move about. The pompoms stayed still for a solid, vibrated for a liquid, and bounced all around for a gas. This is Kymani doing races with a heavy metal wheel down the ramp - you were only allowed to give it one push!
Here is Trisha and Arav checking out the inside of a human body. They were pushing a marble through his intestines! And these girls and picking up different solid materials and seeing how different they weigh.
A cool part of the roadshow was when Fiona was picked during a show to help out. She had to put on a white plastic cover and stand under a bowl of cornflour slime. The interesting thing was the slime didn't come out. It is a solid when you push on it, but acts like a liquid when you pick it up with your fingers. It's called oobleck slime.
Ka'nan was also picked out from the crowd during a show to help the scientist. He had to tip a liquid into a beaker which created a reaction. The scientist said it's a little like toothpaste!
We had a great time at the science roadshow! We can't wait to do even more experiments in class this term and find out more about science!!!
