Pure and Applied science Pure science : observation of natural phenomena solely for the discovery of unknown laws relating to factsApplied science: the discipline dealing with the art or science of applying scientific knowledge to practical problems Such as medicinesInferences &Fair testsWhat is a inference ?What is a Fair test?Answer a educated guess about the surroundingsExample there is a computer so its the computer room.

A fair test is a test carried out under fair conditions.Example when testing drinks on how the react to salt the temperature of the room has to stay the sameVariablesIV: Independent VariableThe variable that is changed for an experiment DV: Dependent VariableThe variable that doesnt change for an experiment Cv: the consent variableThe ending variable/outcome variableObservations/ConclusionsObservationsAnything you notice with your senses such as sight or touchExp the monitor is black.Conclusions The end of the experiment and all the written data is proven right or wrong. GraphsA line graph is a graph that uses points to show information. And it mainly deals with time

A bar graph is a graph that is used when time is not a factorStatementsQualitative statementA statement which does not deal with numbersExampleStudents are wearing blue shirts.Quantitive statementA statement that deals with numbers.ExampleEight students are sick today.

Math terms in scienceMean- The average of the numbers Example- 12345 answer 3Mode The most common/ used number. Example 123445 Answer is 4Median The middle number Example 12345 answer 3 Hypothesis/Theories Hypothesis The question part of the method of science, a explanation for a phenomenonExample The 3 green leaves turn brown because the dry up.Theories- Is a hypothesis that has been tested many times by different people.Examples the Theory of evolutionBig bang theory GroupsControlled groupIs the group that stays the same is not altered.Example- the plant that stays outside in the garden. Compared to the plant indoors that is in shade and constant temperature changes.Experimental groupThe group that is altered during the experiment.Example- the plant indoors is in the shade and the temperature is changing from cold to hot every day.
