Pure and Applied science

Pure – is motivate by there curiousEx: like oil and how humans use it for gas

Applied science- it the exact science of knowledge from the Scientifics fields.

Ex: building a 400 square feet house

Inferences

• Is a logical explanation • Ex: my brother was in the living room and I

was in the computer and I heard a loud sound of something being dropped so I went to check, he dropped a book on the floor.

Fair tests

• It is a test that carried out by fair conditions, when you tests if you do it more then one time, make sure that things remain the same.

• Ex: I’m giving to people a test and they cant study for it so then it’s a fair test because no one has a advantage.

IV/DV/CV

• IV- is what the experimenter changes• Ex: acid or water• DV- is a result to changing the IV• Ex: dissolve speed • CV: is what stays the same in the experiment• Ex: M&M

Observation and Conclusion

• Observation- is something you noticed• Ex: backpacks, pencils• Conclusion- is the summary of your

experiment • Ex: My hypothesis was wrong. It was the acid

which the M&M dissolved faster in. In the water it took longer for the M&M to dissolve.

Bar/Line graphs

• Bar graph- when no time is involved• Ex: In which months would you see more birds Jan, Feb, Mar?

• Line graph- when time is involved • Ex: How much time does it take a boy and a girl to stack 30

books?

Qualitative/Quantitative statement

• Qualitative- is a statement with numbers• Ex: I have one backpack• Quantitative- is a statement with no numbers• Ex: I have a yellow pencil

Mean/Median/Mode

• Mean- finding the average • Ex: 30, 35, 40, 41, 50• Median- is the middle number• Ex: 2, 3, 4, 5, 6,• Mode- is the number most repeated• Ex: 9, 12, 14, 14, 17,

Hypothesis/Theory

• Hypothesis- is a educated guess and cause and affect.• Ex: If I put the M&M in acid then it will dissolve faster• Theory- is having a experiment being tested many time and

have gotten the same answer every time• Ex: there is the cell theory and this is the basic unit of life.

Control/Experimental groups

• Control groups- nothing is done to the group they stay the same.

• Ex: group B didn’t drink water• Experimental- the group is changed• Ex: group A drinks water
