Science blog

   
Week:6
What I have done?
I got to choose between 3 science push and pull activities. They were basketball bounce, ping pong ramps and chair pulleys. I choose to do basketball bounce because I never usually use a basketball and I wanted to see the different forces in a basketball. I made a four square with Hamish.g, heilee, Sean, Jackson and Ruby.p we used a piece of chalk to draw the four square and a ball

What I found out?
I found out that if you push a ball hard and fast momentum and it hits an object it will bounce back because of the force or pressure 


What I wonder?
I wonder why the force pushes the ball back I also wonder why if you push the ball down why does it come back up. 


Week:5
What I've done?
I have done the rocket air balloons.
Done the same as week 4 but the string was longer.

What I found out?
I found out how to put together a data Recording sheet.

What I wonder?
I wonder if we could observer it so we can make changes.



 Week:4
 What I've done?
I have done rocket balloons and catapults.
I put the straw on the string and blow up the balloon and then stuck the balloon to the straw that is attached to the window and the floor.

What I found out?
I found out that it is very hard to get the catapults to fly but it is easy to make the rocket balloons 

What I wonder?
I wonder what I could improve on to make my catapult go further.?
