Unit 1, Concept 1

Question 1

Objective: Define Science.

Answer 1

i: Science = Observing the world and running experiments yo make fact based conclusions.

Question 2

Objective: Give an example of a hypothesis in the correct format.

Answer 2

i: If I dance using brand X ballet shoes, then I will pirouette better.
Format- If _____ then ______.

Question 3

Objective: Explain the relationship between independent and dependent variables within a hypothesis.

Answer 3

I: The Independent variable is what the experimenter deliberately changes or manipulates in the investigation (x axis). While the dependent variable is what changes in response to the independent variable (y axis).

Question 4

Objective: Differentiate between an observation and an inference.

Answer 4

i: An observation is a description of something you can see, smell, touch, taste, hear. This is not an opinion, it must be objective. While an inference is a guess about an object or outcome based on observations. You can make many inferences from a single observation.

Question 5

Objective: Explain the difference between accuracy and precision, and the significance of having data that is both.

Answer 5

i: Accuracy is how close your measurement is to the correct/accepted value, while precision is how close your measurements are to each other. Measurements that are both accurate and precise demonstrate validity.

Question 6

Objective: List the general steps in designing and conducting an experiment.

Answer 6

i: Ask a question, conduct background research, construct a hypothesis, test your hypothesis in your experiment, draw conclusions and research them.

Question 7

Objective: Give an example of a Scientific investigation design, with appropriate constants and variables (IV and DV).

Answer 7

Kadence wants to know if the type of pointe shoe she wears will get her more turns. She buys five different pointe shoes brands: Bloch (which is what she usually wears), Russian, Grishko, Suffolk, and Capizeo. Every one hour pointe class for 2 weeks she alternates her 4 brands of shoes (all equal days) and records how many turns she gets with that shoe. She makes sure she wears the same toe pads, ribbons, and tights everytime.

Question 8

Answer 8

Fact: an objective, verifiable observation

Question 9

Principle

Answer 9

Principle: a statement based on repeated observation

Question 10

Law

Answer 10

Law: a broad concept or principle (HOW)

Question 11

Theory

Answer 11

Theory: An explanation of an observed phenomenon

Question 12

Qualitative

Answer 12

Qualitative: Describes qualities

Question 13

Quantitative

Answer 13

Quantitative: Uses numbers to measure something

Question 14

Independent Variable

Answer 14

Independent Variable: What the experimenter will deliberately change or manipulate in the investigation.

Question 15

Dependent Variable

Answer 15

Dependent Variable: What changes in response to the independent variable.

Question 16

constants

Answer 16

Constants: The aspects of an experiment that are held constant/consistent.

Question 17

Controlled Variables

Answer 17

Controlled variables/group: The variables used for comparison with your experimental variables.

Question 18

Experimental Group

Answer 18

Experimental Group: Groups that are being tested

Question 19

Control Group

Answer 19

Control Group: Groups used for comparison with your experimental groups. This is the “Normal Group”.

Question 20

Graphing

Answer 20

• Have title
• IV = x axis
• DV = y axis

-To find tics to number do range (highest value-lowest) / squares & round
