1. The Language of Science

2.  Hypothesis: a prediction that can be tested; an educated guess base on observations and prior knowledge  Theory: a well tested explanation  Law: a rule of nature that happens the same way ALL the time

3.  Independent variable: the variable that I change in the experiment  Dependent Variable:  the variable that depends on the independent variable  The result  Control group: the baseline condition that all experimental runs are compared to  Constants: things that are kept the same in all the experiments  Data: Quantitative (numeric) vs. Qualitative (categorize)

4.  Observe: to use the 5 senses to gather information  Predict: make an educated guess  Infer: make a conclusion based upon data or evidence  Classify: to arrange information in groups by similarities

5. Scientific Method: a logical approach to solving a problem Steps 1. Identify a Problem or ask a Question A) Background research B) Make Observations 2. Form a testable Hypothesis 3. Design an Experiment 4. Collect and Analyze Data 5. Draw Conclusions 6. Communicate Results

6. State the Problem 1. Question Make it as precise as possible 2. Hypothesis Testable Prediction 3. Experiment Independent Variable: I change it Constant always keep it the same Control Group: Compare all your tests to this group PredictObserve Think

7. 4. Data Dependent Variable Depends on the Independent variable Qualitative means describe or categorize Quantitative means a measure a number 5. Conclusions Does the Data support the hypothesis? If no, revise the hypothesis If yes, then Theory = happens more than once Law = happens ALL the time 6. Communicate Enough detail to allow others to repeat experiment Infer Compare & Contrast Classify
