What you need:
*block of ice, store bought or homemade
*a cup of salt
*liquid water color or watered down food color
*containers for your "paint" (i used disposable ice cream cups from a local scoop shop)
*sponges and/or paint brushes, eye droppers
*a tray with edges (like a cookie sheet with sides)
*paper towels or clean scrap rags
This is super easy, super delightful, wet, messy and scientific to boot! Place a paper towel or rag on top of your tray/cookie sheet. Add you ice block and get ready for some fun! The rag/towel will keep the ice from scooting all over the place. You can of course do this project outside. A kiddie pool would probably be a blast for your wee ones. If using snow you can pile up your mound on the tray or keep it in your bowl, it is up to you.
Ice droppers would be awesome for snow. A sponge brush works best with the ice as well as a squirt bottle. I add all the different elements so that I can ask the kidlets questions. "What do you thing will happen if we squirt the ice with a stream of water? What if we used a mist? Which brush will help melt the ice faster? What would happen if we added salt to the paint first? What if we used hot water?"
He spent the rest of the day checking every half hour or so to see if it had melted yet. Make sure to say things like "Hey! What kind of science are you doing? Are you a scientist? Why is the ice melting? How long do you think it will take to melt to nothing?" All in all let your kidlets explore and have fun. If your wee ones are too small or you don't have any color on hand, hand them some sponge brushes and a bowl of water and let them paint the sidewalk. Tell them they are observing evaporation at work! Most of all...have fun!
Coming up, summer fun with chalk!
