Multiplying Her Strength

Multiplying Her Strength

One of my favorite things to do is visit the elementary school classes at Dorothy’s school and of all my visits, I think my favorite is when I come to the second grade class to demonstrate simple machines. We all pull nails out of a board with a crow-bar (lever) but the real fun is using a block and tackle (pulleys). With their brave teacher attached to the bottom end of the rig, each student hoists her up into the air. In this picture, an excited student is standing directly underneath her teacher while holding her up.

Collyn couldn’t rightly be described as large but she’s a lot bigger than the children in her class. For them, even the smallest of them, to lift her so easily is a real eye opener. As I was leaving, third and fourth grade students saw my rope and tools and got all excited on behalf of the current second grade class getting their chance to lift their teacher. They certainly remember it.

Of course, it’s a treat for me, as well. Then again, Cathy’s not sure what to make of me picking up younger women. ;)

    Hi Henry – your mom sent us the link and I enjoyed the write-up PLUS, I now understand a bit better how the pyramids were built. I’ve read about it of course, but never realized that a block and tackle could actually accomplish so much with little effort!! I know it was more than raising up a teacher… I never was really good in science! Thanks for the lesson to the kids – and to me :-) Lois Gawler
