Now you need to hit the books. You will probably need to go to the library. Here you can search through science journals, encyclopedias and other resources to learn all you can about the topic of your investigation. The idea is for you to understand what is already known about your topic. This may help you refine your question.

For example, let's say that you chose as your question, "What is the effect of the wavelength (color) of light on the growth of pea plants?" You would want to research pea plant growth and find out what is already known about how they grow under different wavelengths of light. Perhaps in your research you would discover that most plants grow best under a particular wavelength (color) of light. Knowing this you may wish to refine or change your question.

In the end you will want to learn as much as you can about what is already known about your area of research. Make sure you keep detailed notes on the resources you use. You will need this information to write your bibliography.

Don't forget that the Internet can be a great resource in your research.

Here are a couple of search engines you might like to try.

Don't forget to include in your Project Log the results of your research!
