The Scientific Method: An organized approach to solve problems. (We do this all the time!)
Steps in the Scientific Method: • Observe • Use your five senses • Define the problem • Hypotheses • “Educated guess” • Reasonable explanations for what was observed
3. Experiments • Tests each hypothesis in orderto prove/disprove them 4. Analysis • Compares the results from the experiment to the original hypothesis 5. Conclusion (Theory) • A hypothesis supported by experimental evidence
Law: Used to describe a natural phenomenon which has been tested over a long period of time under different conditions.
You’re not going to expect this... Let’s try something to practice the scientific method.
