WHAT ARE VARIABLES?

“Science” is the process of conducting experiments on the things around us to determine the cause and effect. For example, if we want to know if a new medicine will work better than an old one, sciences will conduct an experiment to test if the new medicine has an improved effect on the patients.

Our learning goal is to understand how to design a science experiment that is a “fair test.” To understand this, we need to know what variables are. The video below is helpful. Students should also complete these notes What are Variables? and keep them in their Science section of their binders.

CONCEPTS TO KNOW & UNDERSTAND:
  • experiment
  • variables
  • controlled variables
  • independent variables
