Science Blog 9/6/2017 Week 6 Catapults And Rocket Balloon.

_________________

What I've done. I have done rocket balloons and making catapults.

  

What I found out. That rubber bands help the spoon to not go to                        far back and snap. The rubber bands provide tension (tightness) for the catapult.

What I wonder. If you put stones in cotton balls they will go further than  normal. 

I think force is a

 Push and pull and gravity. Gravity is something  that helps us stay on earth .

I worked on the tiered seating.

I worked with Ollie Sean Jackson and me.

I worked with books and cups and wood and a ping pong ball.

I brought the cups and the wood.

It truned  out really good be us every shot went in the first shot miss so we made some bounce platforms and then every shot went in the hole.so it went good made by Sam Findlay

FORCE IS……. A force like gravity and push and pull we tested a pull force game of tug of war  we tested boys vs girls and year 5 vs year 6 .

Gravity draws objects  towards the earth’s centre, pull is a towards you force and push is a forward force.       We 

Today Sanjive  and I finished our catapult data. We finished the one cotton ball one, then  we got on to the 3 cotton ball one. Sanjive 

And I think that it went good here is the data.

When we fired it the spoon went wobbly so we changed the height. It changed a lot like the speed and made it go longer. I changed the angle of the  spoon. We also changed the weight of the cotton balls. We started with 1 and then changed it to 3.

Here's the finished product 

it went good. I think it went good because the height and the structure of the catapult. The furtherest distance with one cotton ball was 12m and 20cm. The furtherest with 3 cotton balls  was 11m 16cm.

Week 9/10 plan. Playground  model. This week in   Science  we got to make a model playground this  is the steps

3 make the stools and stick them on.

 I'm working with hamish g . Liam and Sean. Something that's going good is the  organising.a struggle  is  working together .a improvement is Quality. My next step is to start making.
