Ask a Question • Ask a question you can answer by being able to TEST it • Based on prior knowledge or observations • Why do cats and dogs have hair?
Do Research • Learn as much as you can about the experiment topic • Research may be needed before and after you decide what to do in your experiment • What is the function of hair? What does it look like?

Analyze Data and Draw Conclusions • Examine data to see if the hypothesis is supported or rejected • Explain your results based on the data from your experiment
Communicate Results • Share results with others and get feedback
Identify Questions for Further Investigation • Can your experiment be improved? • Does it lead you to ask more questions?
