  10. Check your story This activity is designed to help you experience the true nature of science –it is built on evidence that can be observed or deduced from our world. Be careful… an important aspect of science involves making observations and collecting data without making assumptions!

  11. Nature of Science – False Assumptions On a sheet of paper, answer the following questions… What allowed you to form your initial hypotheses? How did the scientific method help you to develop your conclusions? How does this activity relate to what happens in a science classroom? How can false assumptions alter scientific conclusions?

  12. 8/16/2011Warm-Up: Identify 5 topics you hope to cover in Biology. Agenda: Name game Nature of science activity Scientific method introduction Homework: Acquire 3-ring binder and dividers

  13. 8/16/2011Warm-Up: Identify 5 topics you hope to cover in Zoology. Agenda: Name game Nature of science activity Scientific method introduction Homework: Acquire 3-ring binder and dividers

  14. Name Game I’m Mrs. Koester and I like….. (Kickboxing, Karaoke, Kaolas, Ketchup, Ke$ha)

  15. Communication - The Right Family The Right Family

  16. The Right Family • Where are the Rights going? • Baseball game • What teams are playing? • Boston Red Sox vs. Minnesota Twins • What color is the family van? • Red • What are the names of the Right family members? • Mr. Right, Mrs. Right, Bobby Right, Katie Right, and Joey Right

  17. The Right Family • Who almost forgot the baseball glove? • Joey • Who ended up having the tickets? • Katie (in her purse!) • Where are the Right family’s seats? • Left field

  18. Nature of Science On a sheet of paper, answer the following questions… How did your focus on passing the object affect how well you analyzed the story? How would you describe “active learning?” Why is active learning so important when completing laboratory investigations? How does this activity relate to the nature of science?

  19. Fortune Telling Fish Problem: What causes the fish to curl? Observe: Make observations and collect information that might be important in answering this question. Hypothesis: Construct a hypothesis in which you predict what causes the fish to curl. Experiment: Test your hypothesis by creating an experiment. Data: Collect and analyze data. Conclusion: Answer research question and summarize results.

  20. 8/17/2011Warm-Up: Work with your group to complete your fortune telling fish lab write-up. Agenda: Fortune telling fish Scientific method notes Homework: Acquire 3-ring binder and dividers. Must have tomorrow!

  22. Scientific Method • Much of the biological sciences deals with solving problems. • Problems can be ecological, environmental, health related, etc. • Scientists use a consistent series of steps (the scientific method) in order to answer questions about the natural world.

  23. Scientific Method • The scientific method is…. • A logical and systematic approach or process to problem solving.  • An organized way of using evidence to learn about the natural world. • Based on gathering observable, measurable, and testable data.

  24. Scientific Method The steps…… Make an Observation Define the Problem Research the Problem State the Hypothesis Perform Experiment Collect and Record Data Analyze Data Draw Conclusions If needed, Do more investigation

  25. Hypothesis S C I E N T IFIC O V E R V I E W Scientific Method Procedures (Experiments) Findings (Conclusions) M E T H O D Data (Results) Repeat steps 3-7 for competing hypotheses. Competing hypotheses may include revisions of the original hypothesis suggested by the results of the testing process.

  26. Scientific Method What the scientific method looks like on paper…..

  27. Scientific Method What the scientific method looks like in real life…….

  28. Scientific Method Let’s break each of these steps down into their individual components: Ask Question Do Background Research Think! Try Again Construct Hypothesis Test with an Experiment Analyze Results Draw Conclusion Hypothesis is True Hypothesis is False or Partially True Report Results

  29. Scientific Method • An organized way of solving problems • 1.Observations and questions • 2.Hypothesis • 3.Experimental procedure • 4.Record results • 5.Draw conclusions

  30. Scientific Method • 1.Observations/Questions • What you see • Inferences are your logical interpretations of what you see. • Questions then arise……. • Why should I care? • Observe that plants near my neighbors yard grow bigger than the others in my yard.

  31. Scientific Method • An organized way of solving problems • Observations and questions • Hypothesis • Experimental procedure • Record results • Draw conclusions

  32. Scientific Method • An organized way of solving problems • Observations and questions • Hypothesis • Experimental procedure • Record results • Draw conclusions

  33. Scientific Method • 2.Hypothesis-scientific and testable explanation for observations • “If……then……” • If I put fertilizer on my plants, then they will grow bigger

  34. Scientific Method • An organized way of solving problems • Observations and questions • Hypothesis • Experimental procedure • Record results • Draw conclusions

  35. Scientific Method • 3.Experimental procedure- designed to test hypothesis • Split subjects you are testing into groups: #1 Experimental Group-given the experimental factor or changed in some way #2 Control Group:-NOT changed Experimental Group Fertilizer Control Group No Fertilizer

  36. Scientific Method • Variable-factor in experiment that is subject to change. • Independent variable- factor in experiment that’s purposely independent(changed)—fertilizer • Dependantvariable—factor that a scientist observes for measuring—plant height and ? • Only test ONE manipulated variable while having many constants.

  37. Scientific Method • Must be a controlled, reproducible procedure Testing effects of only ONE manipulated variable Other scientists need to be able to reproduce it and find same results.

  38. Experimental Set Up EXPERIMENT EXPERIMENTAL GROUP Difference is the Independent variable CONTROL GROUP Compare the Dependent variable Check the results in time Check the results in time

  39. Scientific Method • An organized way of solving problems • Observations and questions • Hypothesis • Experimental procedure • Record results • Draw conclusions

  40. Scientific Method • 4. Results • Record data • Qualitative data -physical traits (qualities) that can be described • Quantitative data -measurements (quantities) that can be taken • Pictures, tables, graphs • Trends noticed

  41. Scientific MethodResults Qualitative? Quantitative? Experimental Group Control Group fertilizer no fertilizer

  42. Scientific Method • Common measurement system • Metric system or (SI)- a measurement system used worldwide by scientists based on multiples of 10 • Mass-grams (g) • Volume-liters (L) • Distance-meters (m) • Temperature- Kelvin (K) or Celsius (OC)

  43. Scientific Method • An organized way of solving problems • Observations and questions • Hypothesis • Experimental procedure • Record results • Draw conclusions

  44. Scientific Method • 5.Conclusions • Hypothesis is either supported or rejected. NEVER “PROVEN!” • If supported further testing • If rejected hypothesis changed and tested again • Can be partly true • Findings always useful!!!
