Members of Mr. Aukerman’s science class are going to do an experiment. They will be working with pendulums. First, Mr. Aukerman talks about the safety rules for working with pendulums. Then, Mr. Aukerman passes out a set of directions for all the students. Roscoe is one of Mr. Aukerman's new students. He has never worked in a science lab. This experiment will be his first. Mr. Aukerman suggests that Roscoe and Elsa work as a team because Elsa has worked in the lab many times. Mr. Aukerman instructs the students to begin. Roscoe jumps from his seat, but he is the only one. He starts setting materials, including metersticks and stopwatches on the lab counter. The other students are busy reading the instructions. Identify what safety procedure Steve does not follow.
