My kids love doing experiments. They ask me almost everyday to do one. After turning to the internet, I found a few we really like and want to pass on. Most are really easy, but they're not always clean, so if you don't like a mess, then preschool experiments aren't for you. Here are a few favorites:
Volcano: good ol' baking soda and vinegar. We put a few TB of soda in a baby food jar and built a volcano around it using playdough. Add a little food coloring for effect, then pour a little vinegar in and watch it "explode." I suggest putting it on a cookie sheet to contain the mess.
Liquid layers: This one is really easy and the kids thought it was awesome. In a clear glass add 1/4 C water w/ a little food coloring. Then slowly add 1/4 C of corn syrup. Next slowly add 1/4 C of oil. Have the kids guess which liquid will go where and then tell them why each landed where it did. Then play around with other liquids; we tried vinegar, pancake syrup and dish soap. The picture is below. It's after adding the other liquids too which caused funky colors.
Slime: Mix equal parts water and white glue. In a separate container dissolve 2 TB Borax with 1 C of water. mix a few TB of the Borax solution with glue and stir quickly and it will become slime that the kids can stretch and play with. It will be a little wet at first, but the more you handle it the drier it becomes. The pic is below.
preschoolrock.com and education.com are good resources. Sometimes I just google preschool experiments and see what comes up.
