54. The Nature of Science Science Theory Expands Challenges Questions Please read about these in your textbook and take notes as you read, Chapter Outline

55. Science A body of knowledge based on the study of nature

56. Body of Knowledge Biologists use specific methods when conducting research

57. Ask a question Observation vs. Inference

58. Ask a question Observation vs. Inference Observation – direct method of gathering information Inferences – logical conclusion based on what you know and what you have learned

59. Tests Conclusions are reached from evidence

60. Collecting Data Experiment Take readings or measurements Important Units Length – meters Weight – grams Time – seconds Volume – liters Temperature – degrees Celsius

61. Collecting Data Experiment Control group

62. Collecting Data Experiment Control group Experimental design Independent variables Dependent variables Constant

63. Dependent variable The independent variable is typically the variable representing the value being manipulated or changed and the dependent variable is the observed result of the independent variable being manipulated. For example concerning nutrition, the independent variable of daily vitamin C intake (how much vitamin C one consumes) can influence the dependent variable of life expectancy (the average age one attains). Over some period of time, scientists will control the vitamin C intake in a substantial group of people. One part of the group will be given a daily high dose of vitamin C, and the remainder will be given a placebo pill (so that they are unaware of not belonging to the first group) without vitamin C. The scientists will investigate if there is any statistically significant difference in the life span of the people who took the high dose and those who took the placebo (no dose). The goal is to see if the independent variable of high vitamin C dosage has a correlation with the dependent variable of people's life span. The designation independent/dependent is clear in this case, because if a correlation is found, it cannot be that life span has influenced vitamin C intake, but an influence in the other direction is possible.

65. Independent variable X - axis

66. Scientific method Form a hypothesis Collect Data Analyze the data Report conclusions

67. Theory Explanation of a natural phenomenon based on many observations and investigations over time. Explanation for a wide range of observations supported by data.

68. Who’s hungry? What should we do? Let’s bake a cake…

69. Lets bake a cake! What’s the first step? What do we do next? When are we finished?

70. Scientific method Form a hypothesis A question to be researched. A testable possible explanation. If accepted after testing, then becomes theory What happened to Pluto?
