Members of my science class are going to do an experiment. You will be working with pendulums. First, I talk about the safety rules for working with pendulums. Then, I pass out a set of directions for all of you. Brandon is a new student. He has never worked in a science lab. This experiment will be his first. I suggest Brandon and Kyle work as a team because Kyle has worked in the lab many times. I instruct you to begin. Brandon jumps from his seat, but he is the only one. He starts setting materials, including meter sticks and stopwatches on the lab counter. The rest of you are busy reading the instructions. Identify what safety procedure Brandon did not follow.
Brandon is not reading and following the instructions given.
