1. Scientific Method

2. Ask a question Finding the reason something is happening (e.g. why do the tadpoles have deformed limbs??) Make observations—be accurate! May also need to collect data

3. Form a Hypothesis This is an educated guess! May have more than one hypothesis per question Make predictions

4. Test the Hypothesis Design and conduct an experiment: – Control group where no changes are made – Experimental group(s) – Only tests one hypothesis/factor at a time

5. Draw Conclusions Analyze your results and then decide if your hypothesis was true or false. If incorrect, reevaluate your hypothesis and try another one (do all steps over again with a different hypothesis).

6. Communicate the Results Tell other scientists about your results—both correct hypothesis and incorrect! So other scientists can evaluate your results and add to your work with their own experiments.
