I created a "science box" for Super J and Tornado. It included a microscope, some test tubes with tops, forceps, and the like. And then I set them loose outside to see what they could find. They really enjoyed exploring and playing in the dirt. We took some of their finds and taped them to some paper for a display.
I can't wait to let them do this when it isn't freezing and February. It will be so much more fun when it is warm outside and there will be lots of critters to find!
But it did let them enjoy the outdoors and nature.
