Studying the weather is one of the easiest and least expensive ways to introduce your child to science. Weather is present every day - in the wintry winds, the sun-drenched summer season, and even the occasional rainbow overhead. If the sun is shining right after it rains, look up and you may catch one.
However, you don't need to wait for rain to show your child a real rainbow. With this activity, you'll recreate the conditions which make rainbows appear, and teach your child the science behind all those pretty colors while introducing the concept of refraction!
