Science blog


Plan for my Science project 29/06/2017 
for my science project I'm making a model playground with Phoebe. Things that are working well are getting things done. 

Phoebe and I do different tasks depending on the resources available at the time instead of wandering around looking for one thing. This is better because we get more done quicker.

 A struggle for me is making things look good because tape doesn't look very nice on most things. So you have to try to make things not look thrown
together and held with tape,
Because that doesn't look high quality.

Something I could improve on is not talking too much while other people are working. Because it annoys other people and also makes me work slower. 

What is working is we share each other's ideas and if one person doesn't like an idea for the playground we think of a compromise instead of fighting.

Overall I'm very happy with how I'm going and working. I'm looking forward to see the results.




Steps for swing
Cut the popsicle to desired size and shape 
Hot glue all the popsicle sticks together to create the frame of the swing.
Tie some wool or string to the top of the frame
Hot glue a cut Popsicle stick to the tip of the wool or string to make the seat of the swing.
And your done

Steps for climbing wall.
Cut an oblong shape out of cardboard.
Paint your oblong shape in grey paint
Add some black to the corners of the oblong shape to make it look more used.
Make small clumps out of hot glue 
Paint your small clumps in a variation of colours.
Glue your small clumps to your oblong shape 
The small clumps are the things you climb on and the grey oblong is the wall.

Steps for balance beam.
Glue and stack six Popsicle sticks. This will be the beam.
Cover two tiny boxes this will be a platform to stand on .
Glue your stack of Popsicle sticks to one tiny box then to the other tiny box.


Steps for trampoline.
Cut a circle out of cardboard. Cut a hole in the centre of the cardboard circle 
Paint the circle black
Hot glue or tape a balloon  to the bottom of the circle 
Cut a circle in a small box 
Paint the small box.
Put the trampoline (the circle with the balloon) in the hole of the box.
The box will hold the trampoline

Steps for flying fox
Cut a long piece of string.
Cover two small boxes in paper.
Hot glue a Popsicle stick (upwards) to each small box.
Tie your string to one small box then go forwards and tie your string to the other box 
Make a handle out of wool.
Tie your handle loosely to the string 
You're  done!!!!!!!!
 
Steps for slide
Curve a piece of cardboard into a slide shape.
Paint the cardboard yellow 
Make two long oblong the size of your curved cardboard 
Paint the oblongs yellow.
Glue the oblong to the sides of the curved cardboard.
Glue your slide (the curved piece of cardboard with the oblongs on the side) to the top of your climbing wall and your done.

Force 23/06/2017
What is force? There are lots of forces push, pull, inertia, acceleration, gravity and friction.
Push and pull is a force causing speeding up, slowing down and changing in direction.
Gravity is a force that attracts your body to the ground.
Acceleration Is a force that increases in the rate of change  speed and direction of an object.
Inertia is when something continues on in its existing motion in a straight line. Friction is a force that resists one object encountered when moving another.
I hope after reading this you know something new about force you didn't know before.

Pulley 23/06/2017
For science I Made a pulley with Sophie. 
First We made the pulley with a cardboard cup,box and string. I found out that if you pull the string on one side, the cup will tilt. 
Yet if you pull the string from the top it is straight. I think this happens because the weight of the cup is uneven.

I wonder if you could make a life sized pulley that delivers books up stairs.
Overall I think Sophie and I should have spent more time on the pulley than decorating the box.

Catapult science 14/06/2017
Today we collected data about catapults. First we did test one, test one had no rubber bands and the distance was 1.2m.

Test two had one rubber band wrapped around it. The  distance I shot it was 1.51m but then my cotton ball wasn't going very far. 

Test three had two rubber bands but only flew 1.21m which I found a bit odd because test two went further. 

Test four went 1m. It had three rubber bands on it.

 My last test, test five had four rubber bands and….it flew 2m and 94cm!

A struggle that I had was wrapping rubber bands around the cotton ball 
because the rubber band would pull all of the fluff of the cotton ball so you were left with a tiny cotton ball.

I wonder how far it would go with ten rubber bands.


Ping pong ramp 9/06/2017
For science I made a ramp out of books and rulers for a ping pong ball. 
First Megan and I made a ramp out of books which were leaning against a shelf. At first the ramp worked but when the ping pong ball reached the end it would roll away because there is nothing catching or holding the ball at the end. 

To improve ramp number one we put a tote tray at the bottom of the ramp so the ball wouldn't roll halfway down the classroom floor.

Then we thought should we make it steeper we added a ruler at the top of the ramp which leant against the top of the shelf. 

When we tested it, it didn't work. 
I think I didn't work because it kept going of the sides of the ruler.
We tried it again and it worked.
I think it worked instead of the other one because we pushed it faster.
 The new ramp made the ball go faster.












Basketball bounce 9/06/2017
This week for science I learnt about basketball.
 Let me tell you about why a basketball bounces. All hollow balls bounce because of the pressurised air inside of them.

 When you drop a basketball, the first thing that affects it is gravity, which pulls it straight towards the ground. 
I noticed that basketballs bounce higher than netball.

I wonder what makes solid objects like those mini bouncy balls bounce?


Catapult science 26/05/2017
For science I've been making catapults. Something I learnt was if you fling a regular cotton ball, It won't go as far as a cotton ball wrapped in tape. 

I don't know why but I think it has something to do with weight. If I did this again I would make a more stable catapult.
