Step 4: Students design ways of testing their science questions.After students finish their background research, they will need to start designing ways of testing their science questions. There are a number of ways of doing this: building and using a model to study a natural process; designing an experiment; conducting a survey or making observations from a field study. It is better for younger students to test questions with direct observations or by using existing models. Older students may be able to create and use surveys or design and conduct controlled experiments.
