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

• scientific method
• recipe
• data collection
• metric system

Which is NOT a step in the scientific method?

• Make observation
• Form a theory
• Collect data
• Form a hypothesis

A testable explanation to a problem that has not yet been tested. 

• data
• theory
• hypothesis
• fact

This is the group that we will compare our experimental group to. This group stays "normal."

• Control Group
• Experimental Group
•  Normal Group
• Weird Group

True or False: a test may have more than one independent variable

• true

• false

What would the independent variable be in an experiment testing which type of paper airplane goes the furthest?

• the type of paper used.

• the distance each plane flies.

• how hard the plane is thrown.

• the type of paper airplane.

The variables in an experiment that stay the same are the -

• Independent Variable

• Dependent Variable

• Constants

• Control

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

• Because it is hard to setup a data table with more
• To know what is causing the changes
• It is what has always been done
• No one really knows

When writing a hypothesis, which variable is the IF?

• independent

• dependent

• control

• questions mark

When writing a hypothesis, which variable is the THEN?

• independent

• dependent

• contol

• question mark
