At school we did two experiments. The first one was coin lab. Fist we had to see how many drops of water can fit on a dry coin. I was in a group with Max and Nikola. We had tweezers and some drop squeezers. We put the drop squeezer in water and filled it. Then we dropped it on a coin. Our hypothesis was that 2, 3 or 5 drops of water but it ended up with being up to 160 in our group!!!Also we tried the same thing with a dry coin.
Another experiment that we did was a paper clip experiment. We tested if a paper clip could float on water. For everybody the paper clip sank, but then we tried to put a paper clip on a paper towel and then removed the paper clip with tweezers without interrupting the paper clip and it floated only once in our group out of 5 tries. The last part of the experiment was tried the same thing as the last one but also putting detergent.All our paper clips sank again!
Over all it was fun! I hope we do more experiments!!!
