This week in science we were doing marble experiments. It was fun. We are doing to do a rollercoaster for the marbles. We are having a contest between the grade 4 boys and girls. Me and the girls are trying to make it awesome and of course work. Today I think we are going to start marking roller coasters out of paper and other materials.
This week in science Grade 5 have been studying shadows. We measured how long our shadow is and drew a graph on it. Then we answered some questions on what pattern we see and why. On our shadows we found out that in the mornings the shadows would be long and straight because the sun is behind us and in the afternoons it would be short and diagonal because the sun is sort of on top of us. This project was an excellent work.
Grade 4 has been working on mechanical energy with marbles and potential energy with marbles. Grade 4 are planning to make a roller coaster track and put a marble on it with both potential and mechanical energy. Grade four are doing girls vs boys on which team can make a track first. It has to work. If it works it is cool. If it does not work it is not cool. May the best team win!
This week Grade 4 did a marble experiment. I made my own experiment by lining 5 marbles up. My marbles were in a line with 2 in a corner, one in the middle and two more in the other corner. I hit the first two so I gave them mechanical energy. They went till the one in the middle. The one in the middle went rolling till the other corner and the ones in the other corner fell off the ruler.
I had to pick a paper that had pictures, names and definition of forms of energy. Then I had to match them up.
I learnt electricity is electrical energy. It is electrons which carry the charge. I found nuclear energy was tough for me.
I learnt that I shouldn’t glue them all at once until I sort them out.
This week in science we learnt about cannonballs we had to answer 6 questions. I learned that it doesn’t matter the size of something. Like if a small canon and a big cannon gets dropped. They both fall at the same time. Next time I will try to read the words a little bit more. I also learned that Aristotle said that not only heavier did objects fall faster than small objects they both fall at the same time. And we had to predict what was going to happen. We had to predict which one will fall first or both. It was interesting that small objects and big objects fall at the same time.
