1. Scientific Inquiry and the Scientific Method Understanding the World Around Us

2. Vocabulary Introduction Observation (Facts) Observations/Facts you make with your senses that you know to be true. Quantitative: numbers Qualitative: descriptions that cannot be put in numbers

3. Vocabulary Introduction Theory

4. Vocabulary Introduction Law If a theory survives many tests it becomes a law. It summarizes observed experimental facts.

5. Vocabulary Introduction Inferring An explanation or interpretation of observations. Inferences are based on reasoning, not random guessing

6. Vocabulary Introduction Prediction

9. Steps of Scientific Inquiry Uses senses to make observations. Makes inferences or predictions based on observations. Research the topic Form a hypothesis Design a controlled experiment to test the hypothesis Perform the experiment and record data Draw a conclusion Hypothesis is AcceptedHypothesis is Rejected Go back and redesign your hypothesis Becomes a Theory Accepted many times and proven mathematically Becomes a Law

10. Variable The one part of an experiment that is manipulated by the scientist Present in the experimental group, not present in the control group. Example: If you were testing the strength of different paper towels (like you did last year) the type of paper towel will be the variable.

11. A Controlled Experiment Has… Control Group Setup according to “normal” conditions Experimental Group Same as the Control Group, but with the variable They are exactly the same except for the experimental group having the variable(the one difference) The larger the sample size, the more accurate the results Important Points:

12. Hypothesis Formation If The conditions you are setting up (like prongs in thesis statement/more than one) Then Your predicted results. (what you think will happen) Because Your explanation for your predicted results. (why)
