Make a list of the things you are interested in. (pets, sports, hobbies, human behaviour, nature)

Is there something you have always wondered about?

Have you done something at school you would like to investigate further?

For each thing on your list brainstorm with a friend, parent or teacher, for questions you could investigate.

Choose the best questions that look most promising and do some research into the topic at the library, on you computer, or ask someone who knows more than you.

Now you know more about the questions decide which one could be most easily investigated by you.

What do you think might happen?

Experiment or observe.
Make comparisons
