Friction: Friend or Foe?
Using a hands-on approach, learners explore the effect of friction on objects. Learners use toy cars, shoes, wood, metal, and more to experiment with the causes and effects of friction. Afterwards, they conduct experiments in which they...

The Mu of the Shoe
What is mu? Emerging scientists explore the coefficient of sliding friction, or mu, and apply its concepts as they complete activities in the interesting lesson. They measure the sliding friction between soles of their own athletic shoes...
Curated OER
Motion Lotion
Learners view a video to explain the meaning of friction. In a hands-on experiment using gelatin, students test the effects of lubrication on friction. They complete a worksheet imbedded in the lesson to describe their observations.

Friction Restriction: Creating a Design Plan to Redesign the Tread of Tennis Sneakers to Increase Friction
Students evaluate the friction of tennis sneakers and redesign them to increase friction. In this physics lesson, students calculate starting, sideways and forward stopping friction. Using quantitative data, they prove that redesigning...
Curated OER
The Addiction With Friction
Learners compare and contrast where friction occurs in robots and bicycles. In this science lesson, students label the diagram of bicycle and robots. They investigate how friction affects their different parts.
Curated OER
Friction and Machines
Fifth graders experimentally determine the relationship of friction to the functioning of machines. They demonstrate that rollers can decrease frictional force and increase speed and research to discover other ways that friction can be...
Curated OER
How Far?
Young scholars explore how different textures provide varying amounts of friction to objects moving across them. They build a tool to measure the amount of friction between a note card and various surfaces by measuring the distance that...
Curated OER
Forces and Machines
For this forces and machines worksheet, students will review vocabulary associated with forces including friction, inertia, and work. Students will also explain how simple machines help to do work easier. This worksheet has 10 matching,...
Curated OER
Types of Forces
Students study scientific names and descriptions of forces. In this motion lesson students organize information into a graphic organizer then teach it to other students.
