1. Scientific Method

2. What is the scientific method? It is a method that is used to find answers to questions about the world around us. It is a method that is used to find answers to questions about the world around us.

3. Is there only one “scientific method”? There are several versions of the scientific method. There are several versions of the scientific method. Some versions have many steps, while others have only a few. Some versions have many steps, while others have only a few. They all begin with a problem or a question to be answered based on observations of the world around us. They all begin with a problem or a question to be answered based on observations of the world around us.

4. What are the steps in the scientific method? Identify the problem: What do you want to find out? What do you want to find out? Use your observations to state the problem as a question. Use your observations to state the problem as a question.

5. What are the steps in the scientific method? Form a hypothesis: Is an educated guess Is an educated guess What do you think will happen? Make a prediction. What do you think will happen? Make a prediction. The hypothesis must be measurable or testable and written in an if….. then…… format. The hypothesis must be measurable or testable and written in an if….. then…… format.

6. What are the steps in the scientific method? Create an experiment: How will you test your hypothesis? How will you test your hypothesis? Write a step-by-step procedure that another person can follow. Write a step-by-step procedure that another person can follow.

7. What are the steps in the scientific method? Perform the experiment: Follow the steps in the procedure. Follow the steps in the procedure. Record data and make observations. Record data and make observations.

8. What are the steps in the scientific method? Analyze Data: Does your data and observations support your hypothesis? Does your data and observations support your hypothesis?

9. What are the steps in the scientific method? Communicate the results: If your hypothesis was correct, summarize the experiment. If your hypothesis was correct, summarize the experiment.

10. Variables Controlled experiment: An experiment in which all the variables except for one remain the same Controlled experiment: An experiment in which all the variables except for one remain the same

11. Types of variables Independent variable(manipulated): the factor that is intentionally changed by the scientist or person doing the experiment. Independent variable(manipulated): the factor that is intentionally changed by the scientist or person doing the experiment. Dependent variable (responding): a response to the independent variable; what you are testing for. Dependent variable (responding): a response to the independent variable; what you are testing for.

12. Types of Variables Controlled variable: the part of the experiment that stays the same. Controlled variable: the part of the experiment that stays the same. For example: Students of different ages were given a puzzle to assemble. The puzzle assembly time was measured. For example: Students of different ages were given a puzzle to assemble. The puzzle assembly time was measured. What are the 3 variables? What are the 3 variables?
