3. Critical Thinking:
Applying logic and reason to observations and conclusion

4. How you use science skills:
Guessing about the future:
Improving the quality of your life:
Identifying problems and coming up
with a solution:

5. Scientific Method:
A critical thinking process used to solve scientific problems. The way scientists find out about the natural world.

6. The Cycle of the Scientific Method
Sample steps of the scientific method: Designing an experiment
State the Problem
Hypothesize or Predict
Conclude
The Cycle of the Scientific Method
Gather data/ plan experiment
Analyze Data
Record & Organize Data
Perform Experiment

7. Hypothesize or Predict
Hypothesis:
A educated proposed answer to a question
Hypothesize or Predict
State the Problem
Hypothesize or Predict
Plan your Experiment
Gather Data
Record/ Organize Data
Analyze Data
Conclude
The Cycle of the Scientific Method

8. Hypothesize or Predict The Cycle of the Scientific Method
Conclusion:
The determination as to whether your results supported your hypothesis
Conclusion
Yes or no?
State the Problem
Hypothesize or Predict
Plan your Experiment
Gather Data

9. Observation: to observe
How do we observe things?
By Using your senses to find out what is going on around you

10. Types of observations:
Quantitative observation:
uses numbers
Qualitative observation:
Does NOT use numbers
Look at today’s weather report.
What are quantitative observations?
What are qualitative observations?

11. Variable
Anything that changes in an experiment (the goal is to change only one)

12. Tools & Models Tools to help us observe: microscope, scales, etc.
Models: skeleton, DNA, map…

13. simulation
Video games, NASA, flight training

14. Closeness of the measurement to the accepted value
Accuracy:
Closeness of the measurement to the accepted value
High Accuracy
Low Accuracy

15. Exactness of a measurement
Precision:

16. Is there a difference between the measurement of 7.0 cm and 7.00 cm?
Explain your reasoning.
