What do you know about the scientific method? Do Now: What do you know about the scientific method? List as many steps as possible. Give an example if you can.
Big 7 - Chapter 1.2 – Scientific Method Critical Thinking Scientific Method Hypothesis Conclusion Variable Accuracy Precision
Critical Thinking: Applying logic and reason to observations and conclusion
How you use science skills: Guessing about the future: Improving the quality of your life: Identifying problems and coming up with a solution:
Scientific Method: A critical thinking process used to solve scientific problems. The way scientists find out about the natural world.
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
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
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 Record/ Organize Data Analyze Data Conclude The Cycle of the Scientific Method
Observation: to observe How do we observe things? By Using your senses to find out what is going on around you
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?
Variable Anything that changes in an experiment (the goal is to change only one)
Tools & Models Tools to help us observe: microscope, scales, etc. Models: skeleton, DNA, map…
simulation Video games, NASA, flight training
Closeness of the measurement to the accepted value Accuracy: Closeness of the measurement to the accepted value High Accuracy Low Accuracy
Exactness of a measurement Precision:
Is there a difference between the measurement of 7.0 cm and 7.00 cm? Explain your reasoning.
