In class we have been learning about Newtons 3 laws of motion. The first one is the law of inertia. That law means that an object will stay in motion in till a force is acted upon it. The second law is Force=Mass x Acceleration. The third law is every action has an equal and opposite reaction. We have been looking at how strong an egg is. We did a an ‘egg’ speriment in class on how much an egg shell can hold. The egg shells cracked after 6kg and I was very surprised on how much it did hold. We also watched a short clip on how much at least 100 eggs can hold and it held 2 cars, and the were not boiled eggs. So eggs are stronger that you think. In class we have also been wanting to do an egg drop. So in groups we designed two ideas, one with a parachute and one without one. Then we decided on who’s idea we were going to do. Then we started building. Me an Donald made the idea without the parachute. Our idea was that we were going to have a cup that the egg was going to be in then four balloons around it to keep it floating But there was a problem. When we checked to see if it would float and it kept on tipping to the side so we had to find a solution. Then we thought of an arrow and at the end of an arrow there is something to keep it keep flying straight so we decided that we were going to make them and put them on our balloons and it would look like an arrow and when we tested it out with the egg in it and when it dropped to the ground the egg had no crack and was safe.I was so glad that our idea worked. Our second idea was with the parachute. Ellen and Abi made this one. The idea was that they made a pyramid to put the egg in and then the put pieces of straws around it so that when it dropped it wouldn’t put force on the pyramid with the egg in it it would put the force on the straws around it. Then they attached the parachute. When they tested it out with the egg in it there was no crack so both of our ideas worked and my group got 1st place.

This year Port Ellen Primary Schools panto is called Ali Baba and The Bongo Bandits. Our panto is about a boy called Ali Baba and he goes of and meets the princess. With his mum they go off and find a magical genie. But the princess’s father doesn’t know that she is gone. And now both of the Sultans gems are gone, his royal ruby and the princess. The hero… Ali Baba finds both gems and takes them back to the Sultan. Although it isn’t that easy. For the panto to help us get better we have been evaluating each other to see what we have done well and what we need to improve on. In the panto I am the mother of Ali Baba, Flossy Baba. I am really looking forward to performing on the night. We have also been learning how to add expression into our acting and making up dances. It is going to be great fun to perform tonight.
about STEM in class. At the high school there was a lot of things to do. My favourite thing to do was Kodu. You got to make your own game and then once you are finished you swapped with the other people in your group. We learned to make our own game on Kodu. In my game you had to dodge all of the hills and try to get to the big castle and if you bumped into the castle you would win but you only have 60 seconds to complete the level and if you don’t get to the castle in that amount of time you would lose. When I was making my game I had to program my character to jump so it would go over the hills and before that I had to program him to move. Before I played the game I thought it would be very easy but when I played the game I thought it was very hard so I had to fix the game. To fix the game I had to put down the hills so people will get to the castle easily. After I fixed the game I could play the game and so could the other people in my group. By Rowan
