OBSERVATION - List a puzzling observation which inspired the causal question
CAUSAL QUESTION - Write a question, that if answered, would explain the phenomenon you observed
HYPOTHESIS - What is a testable explanation for the observation? (Stated as a fact)
PREDICTION - If the hypothesis is tested what specific outcome would you expect to observe? (Use the key words: will, should)
CONCLUSION - Based on your results, do you support or reject your hypotheses? Explain why. Also, propose an alternative hypothesis and/or future experiments?
