For this task we had to pick out of two experiments to do but I chose to do both. I enjoyed learning about surface tension because its cool how a paper click can float on water. Next time I would add more pepper to see if it made a difference. I found it tricky to add the right amount of dishwashing liquid. The dishwashing liquid makes all of the pepper go to the sides. When you fill a cup up with water it doesn't overflow straight away because the molecules of the water stick together. The surface tension can hold a paper clip on the water. These are some photos of the experiments.
Kia ora Thomas,
ReplyDeleteI really enjoyed reading that you completed both of these experiments. Your explanation about how these work I thought was great. Next time you could try to take a video so we can see exactly what happened when you did these experiments. Have you ever done these experiments before?
