  1. Scientific Method

  2. Problem • Always in the form of a question • Example: Do plants need sunlight to survive?

  3. Research - Collect Information • Read books on PHOTOSYNTHESIS • Search the Internet • Read magazines • Asks Experts

  4. Hypothesis –an educated guess • Possible answer to the problem • Complete sentence • Example: Yes, plants need sunlight to produce food to survive.

  5. Experiment • Test your hypothesis • Gather materials • List every step you take • Make observations

  6. Materials Two pea plants Water Closet Sunlight Soil Put one pea plant in each pot with 2 cups of soil Place one plant in the closet Place one plant in the direct sunlight Give both plants half a cup of water daily Observe plant growth for two weeks Experiment-Example

  7. Record Results • Write a Report • Draw Graph • Make a chart • Draw Picture

  8. Growing Plants Inches

  9. Conclusion • Tell whether your hypothesis was correct or incorrect • Example: My hypothesis was correct. Plants need sunlight to survive. The data shows that at the end of 5 days the plant in the sunlight grew 50% taller than the one without sunlight.
