Research for your Science Project
There are any number of sources that you can use to research your science project subject. The best place to start is the school library. You can ask your librarian to help you get a few related books and then browse through them to see what you need to use for the project. Maintain a record of all the books that you use so that you can get them out to refer to again.
If you still need more help get on to the information highway on the internet. There are some great websites related to science on the internet. These sites can probably answer all your questions twice over. The only danger here is that you may end up with a headache trying to sort out which sites information you need to use and which is superfluous.
You must also set a limit to the time that you have for research or else you will keep reading up on the project and never get started out on it. Now remember that your science projects do not always have to be about serious stuff. Even ones which are funny or can bring about some interaction with your viewers can do well in a science fair competition. How about a project on blowing the largest bubble possible?
