On Tuesday, we did one of the experiments from our book “Science Lab in a Supermarket.” We read a section about fruits and vegetables, and then learned how water travels though capillaries in plants.
First, I demonstrated this principle for the girls using water and paper towels.
Then, we moved on to celery and food coloring. :-)
We waited a few hours, checking on our veggie often, and finally we saw this…
EW! Celery capillaries full of really blue water.
This lead to some interesting discussions about human veins and capillaries, and how blood flows, what it does, and why it’s so important. The kids were excited to be making an “army against swine flu” in their bodies. LOL!
We *heart* science. :-)
very cool.
