26. THE SCIENTIFIC METHOD

27. Scientific Method 6 Steps: 1. Identify the problem/ Form a question 3. Hypothesis 4. Controlled Experiment 4. 2. Observations 5. Record and Analyze Data 6. Conclusion

28. Maggots “appear” on Meat

29. 1. Problem/Question:

30. 2. OBSERVATIONS: (relevant to question)

31. 3. HYPOTHESIS: (educated guess) Has to be testable “If.., then…” statement

32. 4.EXPERIMENT - Controlled Experiment = only one variable is changed. - Variable = factors that can change.

33. PROCEDURE Controlled Variables: Manipulated Variables: “Independent Variable” Uncovered jarsCovered jars Several days pass Maggots appear No maggots appear Responding Variable: “Dependent Variable” Keep the same Change intentionally Changes due to IV

34. 5.RECORD and ANALYZE DATA: - Quantitative = numbers by measuring or counting (Chart/Graph) - Qualitative = description (chart)

35. 6. CONCLUSION: “The Hypothesis was correct. Maggots form only when flies come in contact with meat.” -Hypothesis correct/incorrect -Statement of results - Errors and Improvements

36. Several days pass Maggots appear No maggots appear Scientific Method 1. Question 2. Observe 3. Hypothesis 4. Experiment 5. Data 6. Conclusion If IV, then DV “Controlled” Variables

37. Publish experimental results in a Scientific Journal. repetition and validity Allows?

38. Theory = A well tested explanation that unifies a broad range of observations Other Theories?

39. Law = A natural phenomenon that has been proven to occur invariably whenever certain conditions are met.

40. GRAPHING

41. = a visual display of information or data Graph?

42. Line Graph Bar Graph Circle/Pie Graph

43. Independent Variable “X-axis” Horizontal Axis = “Y-axis” Vertical Axis = Dependent Variable ???

44. Which factory had the least amount of defective Cars? How many did this factory have? B 17 per 1000 cars

45. Between what 2 point of mileage does a car’s value decrease the most? How much value does a car’s value depreciate over this period? 20,000- 40,000 $4,000

62. To convert Celsius to Fahrenheit Example To convert 90 o C  F F = (1.8 X 90) + 32 F = 162 + 32 F = 194 90 o C = 194 o F F = (1.8 x C) + 32 To convert Fahrenheit to Celsius Example To convert 82 o F  C C = (F - 32) / 1.8 C = (82 - 32) / 1.8 C = 50 / 1.8 C = 27.8 82 o F = 27.8 o C
