Physicists experiment with the coefficient of static friction on both a level surface and an incline. After answering five pre-lab critical thinking questions, learners go to the lab. They determine the mass required to get a solid wooden block to overcome friction. They also find the angle of an incline required to get the same block moving. A data sheet and 12 analysis questions are provided to guide kids through this propelling experience.
Mr. Kirwan of the Nevada Joint Union High School District has put together a fun group of problems to solve using the coefficients of friction. In some cases the objects in motion are on level ground and in some cases on in inclined plane. Both static and kinetic friction are addressed. With eight questions in all, this can be utilized as a homework assignment or an in-class quiz.
A very scientific-looking but appealing set of slides helps you teach young physicists about the force of friction. First explain what static friction is and demonstrate how to solve problems. Then introduce kinetic friction and the associated equations. Finally, free fall through fluid friction concepts. Toward the end of the presentation, several slides display practice problems for viewers to try. The formatting of these slides is less-than-perfect, but easily edited so that the whole problem is visible.
Students predict the factors that affect frictional force by exploring surfaces and "trains". In this physics lesson, small groups predict and explore frictional force using various surface materials. Exploration time is allowed, and then the teacher brings the group together to discuss the controlled variables in the experiment. The students return to their experiment to draw conclusions.
Students investigate how friction effects the movement of a block across surface areas. In this friction lesson, students experiment with five different surfaces to determine how each effects the movement of a block across them. They experiment with a smooth surface, wax paper, a paper towel, course and find sand paper. They predict and record the results on a graphing worksheet.
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 figure out ways to reduce friction.
Fourth graders investigate friction as a force that is present around us. They observe as a ball is rolled on different surfaces and stopped before discussing what happens. Using different surfaces, they make predictions as to what type of force each will exert, and they experiment to determine if their predictions are correct.
Given a chart of materials and their corresponding coefficients of static and kinetic friction, your physics class can practice solving friction problems. Three scenarios are presented: a hard steel plate on a hard steel table, a Teflon-coated lead block on a steel table, and an aluminum block on a steel table. Learners solve problems involving friction, change, acceleration, and force. This exercise provides straightforward and valuable practice.
Ninth graders experiment with everyday objects to determine the frictional effects on motion. In this friction lesson, 9th graders determine how the type of material, weight, surface area, and speed of sliding objects influences the effects of friction on the object's motion. They identify motions that require friction and others that do not.
Learners explore friction. In this middle school science/mathematics lesson, students collect and analyze data as they investigate the role of frictional force on motion. Learners examine their results to see when more force was needed to move the block and note the corresponding surface.
Students explore the principles of magnetism and friction. They complete an interactive puzzle on the Gizmos and Gadgets computer software, construct a vehicle, build and modify ramps and vehicles to produce various outcomes, and complete a data sheet that graphs the race outcomes.
