The Scientific Method involves a series of steps that are used to investigate a natural occurrence.
3
Easy way to remember the steps to the scientific method is (PHEAC) P -PURPOSE H -HYPOTHESIS E -EXPERIMENT A -ANALYSIS C- CONCLUSION
4
Steps of the Scientific Method Problem/Question 1. Problem/Question: Develop a question or problem that can be solved through experimentation.
5
Steps of the Scientific Method Formulate a Hypothesis 2. Formulate a Hypothesis: Predict a possible answer to the problem or question. Example: If soil temperatures rise, then plant growth will increase.
6
Steps of the Scientific Method Experiment 3. Experiment: Develop and follow a procedure. Include a detailed materials list. The outcome must be measurable (quantifiable).
7
Steps of the Scientific Method Collect and Analyze Results 4. Collect and Analyze Results: Modify the procedure if needed. Confirm the results by retesting. Include tables, graphs, and photographs.
8
Steps of the Scientific Method Conclusion 5. Conclusion: Include a statement that accepts or rejects the hypothesis. Make recommendations for further study and possible improvements to the procedure.

Show how the scientific method is used for each scenario 1) Does the amount of sunlight a tomato plant receives affect the size of the tomatoes?" 2) Will crickets chirp more if the temperature is warmer? 3) I received an F on my test 4) My throat hurts 5) There is blood on the floor, who’s is it? 6) My internet isn’t working

Scientific method example Purpose: I want my car to start Hypothesis: If I put gas in my car, it will start. Materials: 5 gallon gas can, 5 gallons gasoline, money to buy gasoline, a ride to the gas station Procedure: First, I will call my friend Bill and ask for a ride to the gas station. I will take the five gallon gas can and fill it with five gallons of gasoline at the pump. After paying the gas station owner for the gasoline, I will get a ride back to my car and put the gasoline in the tank. Once the gasoline is in the tank, I will attempt to restart the car. Results: The car started on the first try. Conclusion: When I put gas in my car, it started.
