Last friday, I held another Science Fair in our son's Kindergarten class. Took about 10 exhibits of various sizes including bubble one, chinese spouting bowl (my personal favorite), a couple of magnetic exhibits, earthquake table exhibit.... The children were excited and liked almost all the exhibit, different kids liking different exhibits.
I asked the parents to give me some feedback which ones they liked, what they liked and didnt like about Science Fair. Slowly I am beginning to gather feedback and so far, it has been very positive. Wish I could have taken some pictures to capture those emotions but am really happy to hear kids remembered and gave such a positive feedback to parents.
Answer to the last question is - Hot water freezes faster than room temperature water with everything else being the same (same type of container, same freezing conditions etc. Its called Mpemba effect named after a high school student in Tanzania.... Ofcourse you might not see the same effect if say you put hot water in one and really cold water in another as the temperature difference between really cold water and freezing point might be too little for Mpemba effect to occur.
Another experiment/question coming soon....
Have a great Science week
