When we shook the sieves in a rock shaker and weighed them, I like the whole process. Then we put the sieves back to the rock shaker and added the rocks. After that, we put the lid on each sample so that rocks won't come out. We let the machine shake for about 2 minutes. At last, we took the sieves off one by one, and we weighed the sieves to get the last result. It was fun to learn new things!
