Scratch



 http://scratch.mit.edu/projects/24577463/

This is my project on scratch .scratch is a computer coding website which allows you to make games and animations. Scratch is an easy-to-use website that uses simple codes but comes out with really good results. When I want to make a project I go onto you tube and I search cool projects to do on scratch and I comes up with some great results but sometimes if I want to do something simple I have a book with some simple codes in to mess around with. I am also doing scratch at school and I completed the Monkey Mayhem game at school in under 30 minutes go check Scratch out. It is easy to use and fun .

A solar cooker


Cookies in the Solar Cooker!


 
 
The main idea is that a foil lid reflects sunlight focusing it into a black box.
I used a metal tin for my black box because I thought metal would heat up better than cardboard.
I put the tin in a cardboard box and filled the space between them with insulators. I use polystyrene chips. Make sure to seal up all the holes so no heat escapes. I used cling film to make a clear lid but as it heated up it collected condensation.
 
 
I left the box in the sun to heat up so that when I added the cookie dough they started to cook straight away. I could hear the dough sizzling as soon as I put it in.
 
When the sun moved around we had to keep moving the box to trap the sunlight.
It took at least 3 hours to cook the dough.
They tasted OK but the texture was weird.
We cooked the rest in the oven.
