Today our teacher taught us about hypotheses. And it was a fun experiment!
Yesterday our teacher Mrs Kumar told the class that we were doing an experiment. She said that we were going to be doing it tomorrow. And today was the day. Before she said we were going to be using mandarins and she taught a word it was a really hard word for the class. We were all struggling with the answer. She gave us a clue and then she said the word. Hypothesis she said what does hypothesis means we did not know? She said that hypothesis makes a guess. Then we went on with the experiment.
First she grabbed two cups. Then she grabbed two mandarins and she peeled one of the mandarins and left one not peeled. She filled up both of the two cups. She made sure they were both equal then she chose two people from the class dojo. The person was Ejay. He put the not peeled one into the water.
Next she chose another person. It was a boy again named Tupou. He was eight years old once he came to Mrs Kumar’s bean table. The bean table was shaped in a bean shape. The colour of the bean table was white. Once Tupou came to the bean table he put the not peeled mandarin in the cup of water. And then someone yelled out that the orange floats!
Then she told us to sit on the ground in our class and talk about how the mandarins floated. We all sat down on the mat and buddied up with a person and we started talking about the experiment. And we had a little look at the oranges. And started to think about how was it floating.
It was floating because it has air in the mandarin. It was floating just like a boat. Finally we took a look at the other mandarin that was sinking. The mandarin that was sinking was all the way at the bottom. The reason it was sinking was because it did not have a skin and the skin would hold lots of air if it was floating. But it did not have any air and skin. Afterwards we talked to each other and explained how it floats and how it does not float. Once we were done talking we had to explain to our teacher. How did it float and how did it not float.
It was so fun doing the experiment. I really enjoyed the experiment with my classmates. It was as fun as a bouncing castle. I think I would like to do the experiment with my siblings at home. So I can show them how it sinks and floats.
