Science Experiments -- Repeating Activities

I wanted the kids to be able to repeat experiments they
were especially interested in. As we've done each
experiment, I've written the steps out on index cards
for LD to follow. After we've done the experiment I've
printed photos of the experiments on card stock and
placed them on a key ring. LD can flip through the stack
and choose experiments to repeat (and I have them on
file and easy to access in the coming months/years).

For my own benefit, I put together a booklet of the
science experiments I printed out from the internet (I
have a comb binder that hubby got me for Christmas one year.)
