1. What is the Scientific Method?.

3. Scientific Method- a model or guide used to gather information and solve problems Scientific Method- a model or guide used to gather information and solve problems Data- the information that you gather Data- the information that you gather We all use scientific method every day in that we experiment to solve problems We all use scientific method every day in that we experiment to solve problems Ex. Shaking a pen to make it write again Ex. Shaking a pen to make it write again

4. StepMethodKeyword(s) Scientific Method- a model or guide used to gather information and solve problems

5. Step 1 of the Scientific Method 1) Identify and State a Problem Ask a question about what you want to figure out. Which will keep hot chocolate warmer paper cup or Styrofoam cup?

6. StepMethodKeyword(s) 1Identify and State a ProblemAsk a question Scientific Method- a model or guide used to gather information and solve problems

7. Step 2 2) Gather Information (Research) 2) Gather Information (Research) What do other people know about this subject? What do other people know about this subject? Scientists read reports written by other scientists on the subjects that they are studying. Scientists read reports written by other scientists on the subjects that they are studying.

9. Step 3 3) State a Hypothesis Make an educated guess about the answer to your question. (What you think.) If the Styrofoam is thicker then it will keep the hot chocolate warmer

10. Variables A variable is any factor that can change A variable is any factor that can change in an experiment. in an experiment. Variables must be identified in order to test the hypothesis.

11. Types of variables: 1. Manipulated Variable a. Also known as the independent variable a. Also known as the independent variable b. The factor you will be purposely. b. The factor you will be purposely. changing and testing. changing and testing. c. is shown on the c. is shown on the horizontal axis of horizontal axis of a graph. a graph.

12. Responding Variable a. also known as dependent variable variable b. The variable you predict will change as a result of the change as a result of the manipulated variable. manipulated variable. c. Is shown on the vertical axis of a graph

13. Controlled Variable- the variable that stays the same throughout your entire experiment. Controlled Variable- the variable that stays the same throughout your entire experiment.

14. Hypothesis Writing If (manipulated variable), If (manipulated variable), then (responding variable). then (responding variable). A hypothesis is written as an If… then… statement. A hypothesis is written as an If… then… statement. These statements must be written in correct grammatical form. These statements must be written in correct grammatical form.
