Science blogs

Science blog week 9/10 3/7/17


What I am doing:a modle playground

Who I am doing it with:Gabby and Sophie.G

Where: green table


What I need to bring:Toilet rolls,Cardboard


What I need to do before:get plan ticked off,gather and bring things I need to bring.


Steps...
1.Create base
2.Make the playground equipment 
3.Place/glue equipment onto base 
4.Present to class


Equipment and forces used
See saw-push
Zipline-acceleration 
Merry go round-push and acceleration
Slide-push
Spinning thing-acceleration
Swing-push

Reflection
I am designing a model playground that uses forces to activate.

What is working well for me is that we are all working together in harmony and sharing jobs evenly because we are trying to avoid the situation that we had in our last group becaukse we felt left out and we don't want anyone to feel that way with us.

A struggle for me was at the very start I was with Emily,Sophie and myself but Sophie and I didn't  get to do much work so we decide to make our own playground but Emily had most of our equipment so we had to start over.

I feel we are working really well because like I said before we are making things work.

 Improvements we have made include presentation and colour because our playground was made out off just card board but now it involves stuff like
Paint
Beads 
And other stuff to come that we will add in.

Our next step is to get some feedback and do the best we can with our force learning

 What is force?
Force is a strength that happens in our everyday lives like when the branches sway the wind is pushing them.When you run down a hill and you go really really fast that’s acceleration.You know how if you go into space and you float around and on earth we stay on the ground that's called gravity.These are all forces.

What I did this week for science.
 I  collected catapult data. I did my tests with 3 cotton balls and 10 rubber bands and collected data for 
How far it went
How many rubber bands I used 
How many cotton balls I used
 
What I changed from the previous week was the amount of cotton balls  to see if 1 cotton ball worked better than 3 cotton balls.

The materials I used to make my catapult were
Rubber bands
Popsicle sticks
 A spoon 
The materials I used for my experiment were 
A 1 meter ruler
Chalk
Cotton balls
A 30cm ruler

 The data I collected was that three cotton balls went further than one cotton ball. My highest with one cotton ball was 1m 14cm.
My highest with three cotton balls was 2m 74cm. The reason the heavier one went further was because it was more dense and had more mass so it had a better chance  to project through the air so they have more force.

I can use this by knowing what forces I need to use in the future whether I need to use push or pull acceleration or friction or maybe even all of them. 

Something I learnt was why heavier objects went further than light ones.

What I wonder...
How to use my learning of forces in a model playground. 
 
Science blog week 7 15/6/17 
 This week I did a golf course by myself.

I had a bit in my course that was layered so one on top of another so you needed lots off speed to make it otherwise it would fall off the track. 

What I wonder is that would I need speed for it to go down like one underneath each other. 

On my first test run I thought it would be too easy so I added more obstacles so the ball was challenged and it wouldn't be as easy.

Here is a photo of my learning. 

  


Science Blog Week 6 7/6/17
This week Emily and I did ping pong ramps.

What I found out is that some of
 the rulers that don’t have the middle bit have to have barriers so the ball doesn't fall.

What I wonder is that if we tried weaker barriers would it be different,what if I made a ping pong track into the pulley.  

On my first test run Emily released the ball and it didn't work so we decided to change the course when we changed it we needed 2 rulers so I gabbed another ruler it was the last meter ruler because the other one was broken in half so we tried it on the new course and it fell off the ruler because there wasn't any barriers so Emily and I got some maths books and used them to help we tried it and it fell off at the front so we got an orange brick and that solved our problems it took maybe ⅚ tries then we got it here's a photo off the course

    

Science Blog Week 5 1/6/17
This week we made proper catapults what I mean is that we looked at videos and most of us didn't do free for all I looked at a video and you made a pile of sticks and attached one rubber band then stick another popsicle stick at the top then attach  the 2nd rubber band to the pile of  sticks and when I tested it it shot 1 meter.

What I found out about the catapult comparing it to my first one the second one was way better because the spoon on the second one was on an angle and with the first on it was flat so it either went up or went backwards.

 What I wonder is that if it was on more of an angle would it go further.


Rocket Balloons WEEK 4 

This week I did rocket balloons with Kiri. I worked with Thomas A and Sam to make a rocket balloon you need:
Balloons
String
Tape
Straw
and a place to attach the string. What I found out is that with an amount of force it can push something up a steep angle,but if it has too little force there might not be enough force to push it to the top. 

I wonder if it would work going straight up a wall.
