Deciding on an idea
This may take some time and thought as you have to come up with an idea that is workable, and if possible original. It is often one of the most difficult things about doing a science project. When you think you might have a good idea go to the library or Internet and learn everything you can on the topic. Talk to professionals in the field, write or email companies for specific information, and obtain or construct needed equipment. Sometimes the most interesting projects come from things that you like to do in your spare time or maybe some course you did over the summer holidays. Think of your hobbies, sports, clubs, chores at home, etc. Is there some aspect of these that you could measure and test?
