Variables

Variables: All the factors that make up a FAIR experiment.

• Beaker

• liquid

• Egg

• Time

Poll

Which of the following would you like to change about the egg experiment?

• Type of liquid

• amount of salt

• Age of egg

• color of egg

INDEPENDENT VARIABLE: The one thing that you (the scientist) changes or manipulates

• type of liquid

• type of egg

• age of egg

• Amount of salt

DEPENDENT VARIABLE: depends on the independent. It is the result that you measure or observe.

• Eggs ability to float

• 
  

• 
  

• 
  

Formulating a Testable Question

• How does the INDEPENDENT VARIABLE affect the DEPENDENT VARIABLE

• How does changing INDEPENDENT VARIABLE affect the measurement of DEPENDENT VARIABLE

• How does changing ____________ affect the egg's ability to float?

Write OUR testable question into your Egg Experiment Document

Type done in the message box when you are done.

Formulating a testable hypothesis:

• If I change the INDEPENDENT VARIABLE then the DEPENDENT VARIABLE will change.

• If I change the INDEPENDENT VARIABLE then the egg's ability to float will change.

Procedure: steps to perform experiment.

• 1. Gather Materials

• Complete for homework.
