  1. 1. The Scientific Method
  2. 2. 1. Steps of the Scientific Method1. Ask A Question– Determine the question or problem that is trying to be answered2. Gather Information - Gather as much information about the topic as possible3. Form a Hypothesis – A proposed answer to the question, written in an if/then format
  3. 3. Scientific Method (con’t)4. Test the Hypothesis – design and carry out an experiment A. Independent (manipulated) Variable B. Dependent (responding) Variable C. Controlled Variables5. Record and Analyze Results – Summarize what the data means6. Draw a Conclusion – Restate the question and how you came to the result that you did
  4. 4. 2. Scientific Method Examplea. Ask a Question: “What light color will produce the tallest tomato plant?”b. Gather Information: Research the purpose of light in helping a plant grow, how long it takes for a tomato plant to reach maturity, amount of water, fertilizers needed, etc.
  5. 5. Scientific Method Example (con’t)c. Form a Hypothesis - IF tomato plants are grown under a _____ light, THEN they will grow faster than plants grown under ____, _____,or _____lightsd. Test the Hypothesis – Design and carry out an experiment – list the materials and procedure Materials: Four 5cm tall tomato plants, soil, water, metric ruler, plant pots, red/green/blue/white lights
  6. 6. Scientific Method Example (con’t)d. Test the hypothesis (con’t) 1. Gather materials 2. Plant each tomato plant in a pot containing the same amount of soil 3. Measure plants on day 1 as the initial height and record. 4. Place one plant under red light, one under blue light , one under green light, and one under white light. 5. Water plants daily with 50 mL of water 6. Measure plants every third day and record. 7. Compare growth.
  7. 7. Identify the following variables in the tomato experiment Independent Variable Dependent Variable Controlled Variables (3)
  8. 8. Scientific Method Example (con’t)e. Record and Analyze Results Light Day 1 Day 4 Day 7 Day 10 Color Red 5.0cm 7.3cm 9.9cm 11.7cm Blue 5.0cm 7.5cm 10.2cm 12.3cm White 5.0cm 8.1cm 10.9cm 14.5cm Green 5.0cm 6cm 6.7cm 7.2cmIn addition to creating a graph, this is also when you would talk about possible errors in the experiment. List some errors that you see with this procedure.
  9. 9. Scientific Method Example (con’t)F. Draw a Conclusion – What conclusions can be drawn from analyzing the data? In other words, under which light did the tomato plant grow best? Worst?
