  1. Topic: Scientific MethodDo Now: What students are up to NO GOOD?!?

  2. Scientific Method Research Analysis (step 5) Observation/ Measurement (STEP 4) Question (STEP 1) Conclusion (step 6) Hypothesis (STEP 2) Experiment (STEP 3) If data does not support hypothesis

  3. When designing an experiment, scientists need to think about variables. • A variable is any factor that can affect the result of an experiment.

  4. Read the information below and then answer the questions. SpongeBob loves to grow flowers for his pal Sandy, who loves big, colorful flowers. He found a new brand of seeds coated with a special “booster” fertilizer that said it would produce huge flowers. He planted 5 of the new seeds in one container and 5 of the old brand of seeds in another container. He placed both containers on a sunny windowsill and watered them every day. He measured the diameter of each flower, which is shown in the chart. • Which group was the control? 2. What is the independent variable? 3. What is the dependent variable? 4. What is the average diameter for each group? 5. Which seeds are the best for big flowers?

  5. Read the information below and then answer the questions. SpongeBob loves to grow flowers for his pal Sandy, who loves big, colorful flowers. He found a new brand of seeds coated with a special “booster” fertilizer that said it would produce huge flowers. He planted 5 of the new seeds in one container and 5 of the old brand of seeds in another container. He placed both containers on a sunny windowsill and watered them every day. He measured the diameter of each flower, which is shown in the chart. The seeds without the booster fertilizer • Which group was the control? Booster fertilizer on the new seeds 2. What is the independent variable? 3. What is the dependent variable? Size or diameter of the flower Old = 10 cm, New = 12 cm 4. What is the average diameter for each group? 5. Which seeds are the best for big flowers? New seeds w/ the booster

  6. hypothesis vs theory vs law • Hypothesis: a educated guess based on observation • Theory: what one or more hypotheses become once they have been verified and accepted to be true • Law: a statement of fact: true, simple, universal, absolute (often from nature) The biggest difference between a law and a theory is that a theory is much more complex and dynamic. simple analogy can be made using a slingshot and an automobile.
