It's time to hit the books (or in this case, the internet) and start researching your topic. You'll want to gather as much information as possible to help you formulate a hypothesis and make some educated guesses. This is where things can get really interesting, as you discover new facts and start to connect the dots.
For example, you might learn that plants have a natural tendency to grow towards light sources, a process called phototropism. Who knew? Now you're starting to get a handle on things, and your hypothesis is starting to take shape. It's like solving a puzzle, and you're just a few pieces away from the big picture.
