Nature of Science Review

This variable in an experiment is purposefully changed.

• dependent variable

• independent variable

• data

• control group

Experiments should be repeated over and over to see if the results are the same each time. What is this called?

• Repeated trials

• Validity

• Constants

• Hidden variables

A series of steps used by scientists to solve a problem or answer a question. 

• scientific method
• recipe
• data collection
• metric system

Mr. S. sets up an experiment to see how the mass of a ball affects the distance it rolls off a ramp.  Identify the independent variable.

• distance traveled by the ball
• height of the ramp
• mass of the ball
• weight of the ball

CCSS.HSF.LE.A.2

A student is planning an experiment to find out how the height from which he drops a ball affects how high the ball bounces. The dependent variable is the _____.

• Diameter of the ball
• Force acting on the ball
• Height that the ball bounces
• Height from which the ball is dropped

When experimenting with the growth of a plant, a scientist uses three (of the same type of) plants, two different fertilizers, equal light, and equal water. What type of variable is the fertilizer?

• Independent
• Control
• Compound

CCSS.HSF-LE.A.1C

If I study for my scientific method quiz, then I will have a better test score. What is the dependent variable?

• Scientific Method
• Studying
• Independent variable
• Test score

This part of the experiment serves as a basis of comparison; it does NOT receive the independent variable.

• experimental group

• control group

• data

• variables

Why do we want to test only one independent variable at a time?

• Because it is hard to setup a data table with more than one variable
• To better identify what is causing the changes
• It is what has always been done
• It's easier to perform the experiment
