As soon as kids can reach a faucet, it seems they are drawn to splashing around in the water—much to the chagrin of your kitchen floor. Turn your little bit’s intrigue into intellect with these simple water-based science experiments that you can do at home.
What you need: Food coloring, tablespoon, five glasses or plastic cups, water.
How to: A great follow up experiment to "Egg Float" listed above, this project starts by adding one tablespoon of sugar to the first glass, one tablespoons of sugar to the second glass, three tablespoons of sugar to the third glass, and four tablespoons of water to the fourth glass. Add three tablespoons of water to each of the first four glasses, stir until dissolved (if it doesn't dissolve add one more tablespoon to each cup. Add 2-3 drops of different food coloring dyes to each of the four glasses, and stir. Pour 1/4 of the solution from the first glass into the fifth glass. Repeat with each consecutive solution-filled glass. To make sure you don't disrupt the layers, pour each consecutive layer over a backwards spoon.
How it works: The layers are made of different densities—the lighter layers sit on top of the heavier layers.
