2. Types of Science Pure scienceApplied science  Pure science is manmade. It is motivated out of science.  There is no immediate impact on humanity.  Example: faster cars, taller buildings, heat resistance materials.  Applied science helps humanity immediately.  Example: vaccines, antibiotics.

3. Inference  An inference is logic.  Example: we drive cars to get places faster, people get jobs to get money.

4. Fair tests  A fair tests is a fair and respected tests.

5. Variables  IV: (Independent variable ) is what you the experimenter changes.  DV: (Dependant variable) is what changes as a result to the experiment.  CV: (Constant variable) stays the same.

6. Observations  An observation is what you notice.  Example: I notice that half the class it wearing black. I notice that its cloudy outside.

7. Conclusions  Conclusion is an summary of the experiment.

8. Graphs Line graphBar graph  An line graph is when u deal with time.  An bar graph is when you do not deal with time.

9. Statements QualitativeQuantitative  Has no numbers.  Example: that tree has a lot of apples in it. There are a lot of cars in the parking lot.  Has numbers.  Example: those 3 flowers has 6 petals. There is 15 fish in that pond.

10.  Mean: is the average. You add the numbers together then divide by the amount of numbers. Example – 2+2+2+2=8/ 4= 2  Median: the middle number. Example – (1234567) 4 would be the middle number.  Mode: most repeated numbers. Example – (12234) 2 would be the most repeated number.

11. Hypothesis Theory  An hypothesis is an educated guess that is tested with your experiment.  Example: If I put the ice cube outside then it will melt faster.  Is when an experiment has been tested for many times by different scientist and the results stay the same so it the scientific community they will call this a theory.

12. Control groupExperimental group  An control group doesn’t change in stays the same.  An experimental group does change.
