Curated OER
Friction
Students explore how friction change motion and why friction is important. Students set up an incline plane. They slide wooden blocks down the incline plane and measure the distance from the end of the track that the block moved....
Curated OER
Science : Friction
A few students are asked to step outside. Then have half of the students in the class rub their hands together for about one minute. When the two students come back into the room ask them to touch each students hands quickly, then...
Curated OER
Building the Car (Mechanics and Motion)
Students design and begin building a car out of K'NEX parts after a class discussion on the components of the car, the constraints and goals of the design, the type of testing that will be performed, and a demonstration of a basic...
Curated OER
That Mu You Do
Young scholars discussion frictional force, kinetic friction, and static friction and the role each plays in acceleration and velocity in relationship to a car and the road on which it is traveling. Students complete instructional...
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
Away You Go
Students build Lego cars which have two different types of tire surfaces. They roll them down ramps that have both rough and smooth surfaces to determine how friction affects the car as it rolls.
Curated OER
Peak Performance
Students design and build a car that is capable of traveling across the floor quickly, and also up a steep ramp.
Curated OER
Egyptians as Engineers
Student design and build Lego vehicles that drag given amount of weight up an incline. They show how this demonstrates Egyptian methods of pyramid construction.
Curated OER
Sliding and Stuttering
Students measure frictional force existing between a moving cup and the surface it slides on. They conduct the experiment and answer discussion questions.
Curated OER
Does Contact Area Matter?
Students work together to design and implement an experiment on friction. They test to see if contact area affects the amount of friction. They discover how engineers use friction to make certain products better.
Curated OER
Watch It Slide!
Students work together to examine inclined planes. They create a plan to raise rocks to build pyramids. They discover the changes that occur when the angle is increased or decreased.
Curated OER
SLIME!
Young scholars learn the effects of friction and examine how certain lubricants can only be used with certain materials.
Curated OER
RESISTANCE IS FUTILE
Students explore friction and use objects such as coins and marbles to study the concept.
Curated OER
Slime!
Students participate in a science experiment in which they try and move gelatin cubes with and without a lubricant. They examine the concept of friction and resistance to motion.
Curated OER
Winds Over Land vs. Ocean
Students explore friction and the way it impacts wind over the ocean compared to over land.
