The Science Project

Al is working on his science project, which is due Monday. He is going to have a battery operated four cylinder engine. I started him on the assembly of said engine, thinking, "It can't be hard for he and his father to finish. The man DOES have an engineering degree, and I don't." My husband has pointed out several times during the course of our marriage that he is the math and science trained individual and I'm trained in other, less important stuff. so can somebody tell me why I'm performing damage control and quality checks on the project. Why Al wants me around while they work on the project? Hmmm...
