I'm not great at slotting in science to our homeschool, so its great when things"just happen". Like this recent activity, where three men made a robot from an empty drink can. Don't ask me how. I just took the pictures! But if I could figure how to post videos to posts I could show you how neatly it worked. Ds(11) did most of the construction with ds(7) as audience and dh there to "offer suggestions"
