The Scientific Method:What are the steps? • Observation – Look at the world around you, and the material that inspires question. Develop a question that you could test. • Hypothesis- Give an educated guess of what the answer to your question could be. • Experiment – Design a way to test your question, using one control, and one variable. • Conclusion –What were the results of your experiment? Do you accept or reject
Devolop your own experiment: Question: “Does adding energy increase the rate of evaporation?” Supplies: • 2 quart-size zip-closing plastic storage bags. • Hot water • Room-temperature water • Paper towel • Eye-droppers Work with a partner to write up an experiment. Remember to include OHEC.
