Unit 4 Lesson 1 Kinetic and Potential Energy: PE Focus

Multiple Choice

A group of scientists wanted to know if the size of filter paper would impact the amount of time it takes the filter paper to rise during a chemical reaction. Several different sized filter-paper disks were soaked in a beaker with a solution and placed into another beaker with a solution where a chemical reaction took place that produced a gas. The gas bubbles collected on the filter paper, making the filter paper rise to the top of the solution.  What is the independent variable for the experiment?

• size of the filter paper

• amount of solution added to the filter paper

• amount of time it takes to rise

• amount of solution in the beaker
