If you are anything like me you will want to succeed in most things that you do. Entering your child's great science fair projects into a competition is no different - you want to see your child do well and you want to win. In my opinion the most successful science fair experiments are the most simple ones, below are a few great science fair projects that you and your child can enter into any competition.

The first of the great science fair projects covered will be to make your own 'hovercraft'. This will prove to be a pretty cool choice for most children. First of all you need a cheap, blank CD or DVD. After this you need to get hold of a sports drink bottle top ( you know the ones that pop up and re-seal after every sip ), a balloon and some craft glue.

Now stick the bottle top over the hole in the CD so that air can get through the lid and out of the CD. Get your balloon and blow it up. Do not twist the end of the balloon but rather place over the top of the bottle top making sure not to much air escapes. This is the cool part - when you are ready pull up the lid and watch the hovercraft travel along any flat surface, one of the really great science fair projects.

Another of the really popular great science fair projects is to demonstrate how to create your own cloud, a word of warning though - this project uses matches so adult supervision is needed close by at all times. Get yourself a large jar and a jug of water along with a box of matches. Also get hold of a latex glove.

Pour a bit of the water into the bottom of the large jar up to about three centimeters high. Get the adult supervisor to strike a match and hold it inside the jar just above the water - when the match goes out drop it into the water. Quickly place the latex glove, fingers first, into the jar and pull it's edges over the rim of the jar sealing the jar completely. If you look inside the jar there is no smoke visible. Get the child to place their hand into the glove end draw it out of the jar - watch the cloud appear every time you draw the glove out!

This is one of the great science fair projects that costs next to nothing and is simple to pull off. Remember, the cloud experiment must involve an adult to be carried out. Why don't you give these two a go and get some ideas for your own great science fair projects.
