Stopped off to visit my friend Ellen in her science lab this afternoon. She works with students in Grades One and Two, and, as you can imagine, their lessons are all experiential. Here you see some different gears for a lesson on simple machines. Ellen pointed out a piece of tape she had fastened to one of the beater blades so the kids can watch how many revolutions the beaters make as the handle makes one complete turn. This egg beater may be an old-fashioned device from the past but I know I could not have invented it. In fact, if humankind were dependent on my engineering skills, we'd all be eating raw meat and grass.
allison, we have one of those "old-fashioned devices from the past" in our kitchen drawer....a manual whisk that used to be my grandma's !!!! We still use it sometimes !!!
