Lesson overview:

Students will investigate friction by
a) using inquiry to make observations about particular surfaces, receiving direct instruction related to the inquiry activity, and then by conducting an investigation, collecting data, and drawing conclusion about different surfaces – how those surfaces affect motion, and how friction plays a role.
b) They will compare how different surfaces affect motion by comparing the distance an object travels on various surfaces.
c) Students will draw conclusions based on the information they collect.
d)  Students will learn how a Zamboni machine reduces friction on ice as part of this video on Knowitall.

Essential Question:

How does friction affect movement?
