When I was with Mr Beck I did an experiment. We pushed a ball into the water. The water pushed the ball up and gravity pulled the ball down. The basketball went up high but the tennis ball just floated.

We did inquiry with Mr Beck. We pushed the ball down and the water pushed it back up again. When I put my hand in, I froze!

Floating Ball
By Franki
You will need: some foil, some paper and a straw.
1. You need a straw.
2. You get a piece of paper and fold it into a 3D cone and sticky tape it to the straw.
3. You get a piece of foil and roll it into a ball.
4. You get the rooled up ball of foil and put it in the cone that you made. You practise blowing it in the air.
In Inquiry we are learning about push/pull forces. One day we went to Buddies and made a floating ball. But sadly mine didn't work. So I made one at home. That worked! The force of air pushed the ball up, and gravity pulled it down again.

One day we went to our Buddies to make a floating ball activity. The materials were: pen, paper, coloured straw (or a plain straw), scissors and foil.

Paper helicopters
We made paper helicopters. We used specially cut and folded paper and a paper clip. We experimented to find ways to make the helicopter fall to the ground more slowly. The push of air slowed the fall, but the pull of gravity was always stronger.
