On Thursday the 22nd of April my class, Room 5, made a gooey substance. The only different variable was that one pot was going to be heated and the other was going to be left at room temperature. Both pots were stirred with a wooden spoon, they both had the same ingredients and the ingredients were poured in at the same time.
I predicted the pot left at room temperature was going to turn into obleck. Obleck is a substance that is runny, but when you squeeze it, it becomes hard. It is an interesting substance. I was the time keeper because we were going to measure it every minute. The first experiment was a complete disaster because Ms K used icing sugar instead of cornflour! It was a great laugh. No one noticed for 3 minutes. We had to empty both of the pot's contents and clean them out. Then it was take two!
In the second attempt we got it right. We put cornflour in both of the pots. After about 2-3 minutes the one on the heat started to get a few blobs in it. It was too hot to touch. Then at four minutes it was kind of turning into slime or something! After 5 minutes Ms K picked it up on the fork and some fell off. I managed to catch some on my finger. It was gooey, slimey and hot. My question is:What would happen if we put three cups of cornflour in, instead of half a cup, and kept the water the same?
