Question 0

5 Keys to Good Science Experimentation

Answer 0

1. Make sure the experiment fits the hypothesis 2. That there is only one variable being tested 3. That all other items in the experiment are controlled (control group and constants) 4. All data is analyzed, recorded, and organized for accuracy and meaning. 5. The experiment and results are repeatable.

Question 1

7 Steps of the Scientific Method

Answer 1

1) Observe and form a question 2) Research 3) Hypothesis 4) Experimentation/collect and analyze data 5)Conclusion 6) Repeat work 7) Theory and Laws formed after enough trials (repeat results)

Question 2

Scientific Method

Answer 2

A way to solve and explain a problem or natural phenomenon while removing human bias and opinion. It’s a critical procedure that allows validity and consistency in the science field.

Question 3

Hypothesis

Answer 3

A tentative, testable explanation to a natural phenomenon.

Question 4

Null hypothesis

Answer 4

A hypothesis that the explanation is try to reject. (The opposite hypothesis)

Answer 6

0.01

Question 7

State the metic system prefixes in order from least to greatest

Answer 7

Milli, centi, deci, basic unit, deca, hecto, kilo

Question 8

What are the 3 basic units?

Answer 8

Gram (g) Liter (L) Meter (m)

Question 9

Independent variable

Answer 9

Affects the dependent variable. The treatment or what the experiment is doing. X Axis

Question 10

Dependent variable

Answer 10

Is affected by the independent variable. The outcome and what is being measured. Y Axis

Question 11

Positive Relationship (slope)

Answer 11

Both X and Y increase over time,

Question 12

Negative Relationship (slope)

Answer 12

One variable increases while the other decreases

Question 13

Neutral Relationship

Answer 13

Y value stays constant over time

Question 14

Causation

Answer 14

One variable causes the other to change

Question 15

Correlation

Answer 15

The variable both change but due to an unknown, outside factor

Question 16

Conclusion

Answer 16

Use reasoning to show how your data is all related and what trends you can see.

Question 17

What are the 2 types of reasoning and describe both of them?

Answer 17

Inductive- Conclusions based on actual, first-hand experience, witness, or observation.
Deductive- Conclusions drawn on inferences, not actual empirical evidence.

Question 18

Theory

Answer 18

Organized system of accepted knowledge that explains a phenomena

Question 19

Double blind verification

Answer 19

Conclusions and results are sent out to other scientists anonymously to be viewed and edited.

Question 20

Describe the differences between pure and applied science.

Answer 20

Pure- exact science of producing scientific theories, but there may be no practical usage. Uses math and theoretical physics
Applied- used to answer problems, uses biology and chemistry

Question 21

Name Factors that influence valid science

Answer 21

Sample size, number of trials, lack of communication, opinion/bias

Question 22

What is the most common graph used?

Answer 22

Line graph

Question 23

What can you do with graphing?

Answer 23

Notice trends, relationships, and overall understand what the data means.

Question 24

What goes on the Y axis?

Answer 24

Dependent variable
