It’s that time of year again, the time when the second graders at WCA learn about simple machines. I’ve posted pictures three times in the past, although we didn’t get to do it last year. There’s a new second grade teacher at the school but she was willing to put herself in her students’ hands, literally. Each one was able to lift of off the chair, using six pulleys and a length of rope. This is not only something the students can go home talking about. I have a feeling she’ll be telling the story, as well.
