What is the objective or goal of the lab? How does it relate to what you are doing in class? What background information is there about the topic of the lab?

What are the variables?◦Independent - what you modify/change◦Dependant - what you measure/observe◦Control - what you keep the same

Objective:◦Usually given to you What are you doing in this lab? How are you doing it?

ExampleExample: The purpose of the “Effect of Sunlight on
