Science is all about understanding the world in which we live, and our fun science projects for kids are a great way to do just that. You'll be amazed and entertained by the various projects -- everything from learning how to make invisible ink to creating "killer slime" to grossing out family and friends with virtual vomit and pseudo snot.

There are great ways to get your hands icky and sticky, as well as less messy projects, like creating your own legends or starting a rock collection. Most of the projects use common items (just open the kitchen cupboard or the refrigerator), so you won't have to run to the store before you can get started.

Adult help or supervision is required for some projects, but each one is fun for kids. Get ready to create, invent, and learn about your world.
