I do the same science lesson with both Andrew and Christopher, together.
We have been talking recently about how different muscles and bones have different jobs
and how God created them each to do their own job just right.
The "object lesson" was to try to write your name using your feet instead of your hands
and to walk on your hands instead of your feet--boy, did they ever laugh while trying!!
We talked about how some people have to learn to do things without
their hands or feet;
we decided we are very thankful that all of our hands and feet can do their jobs well!
