1. Aim: How do scientists use the scientific method to solve a problem?
Do Now: 1) Take out the homework questions 1-5.

2. What is the Scientific Method?
A step by step problem solving procedure based on gathered evidence rather than what you believe.

3. State the problem
Form a Hypothesis
Perform Experiments
Collect Data
Form a Solution or Conclusion
Repeat the experiment
Steps of the Scientific Method

4. Steps of the Scientific Method:
S.H.E.D.S Repeat
Copy the following:

5. The scientific method always includes the following:
Hypothesis: Prediction or an educated guess.
Variable: Factor being tested.
Control: used for comparison.
Constant: factor that stays the same

6. There are 2 kinds of variables. What are they?
Dependent
Variable
Independent
Variables

7. Independent Variables- these variables are changed by you
Independent Variables- these variables are changed by you. Why is the independent variable changed? To study what happens to the dependent variable.

8. *These variables depend on something else
Dependent Variable- this variable responds to changes in the independent variable.
*These variables depend on something else

9. You are testing the affect of the independent variable on the dependent variable!

10. An observation is the perception of something with our senses.
Observations & Inferences
An observation is the perception of something with our senses.

11. An inference uses observations to form an explanation, determine a cause, or draw a conclusion.

12. Observation or inference?
A weatherperson looks at a weather map and predicts a storm is coming.
Observation or inference?
