My youngest (age 4) has been experimenting a lot with her art, lately. Most recently she's discovered she can flick tiny bits of her crayons onto her page, and then rub them in, with a spiral pattern. It's been great fun for her, but hard on our crayons.
I decided to distract her from chipping the crayons away, by showing her how she could use a napkin to "polish" her completed drawings, not only making them shiny, but also melting the crayon just enough to blur the lines, and blend them together. She was thrilled.
And, thanks to MaryAnn Kohl, and Jean Potter's Science Arts, I was able to turn the art lesson, into a science lesson, too, by demonstrating to C, that the friction of two objects rubbing together, like her hands...
And, in the case of the napkin on the crayon, it's enough heat to melt the wax of the crayon (phase change!).
Kohl and Potter's book is full of messy, textural art, like you might expect from their craft books, but with a nice box on each page explaining the scientific principal behind what is happening. So painting on the sidewalk with water, becomes a lesson in evaporation, or running a straw through oobleck, with food coloring on top, is all about symmetry.
The book is a little out of date, in that a couple of the activities call for overhead projectors, or slide projectors, but if your in the mood for some messy, art related crafts, that won't produce fridge worthy art, but will teach a lesson in science, then you don't want to miss it.
Or, for more fun with science (and maybe less with art), check out this week's Science Sunday link-up, at Adventure's in Mommydom.
It's great to be a homeschooler.
