Kinetic Friction. For this experiment, each child chose a matchbox car. I made a ramp out of foam core and poster board, leaning one against a small stool for an angle. We wanted to measure whether friction increased or decreased with different surfaces, so I placed various materials on the bottom of the ramp during each round of racing.

First I look at the inclined plane often done as an experime It is not important for children at a young age to understand the technicalities of friction. What this experiment for kids does show is that materials are different and depending on the characteristics of the material they behave differently. Children begin to notice the way different materials feel different. The classic experiment in physics used a wood block with 4 surfaces (such as different sandpapers) to slide on the board.

Rüdiger Berger and his colleagues therefore devised an elegant experiment to measure the forces needed to There are sliding friction experiments, a phone book friction experiment, a way to make rice stick together, an experiment to create frictional heat, and lots more 2016-jan-14 - STEM mom shares a friction inquiry lab.

Frictional forces are less on smooth surfaces, which is why we slide more easily when wearing socks. Friction is also the reason you can hold a book, and the reason why you don’t slip when walking! The ground and other solid surfaces can cause friction, called dry friction, but fluids (liquids and gases) like water and air can also cause frictional forces, called fluid friction.

Friction, simply described for students in elementary school is any force that slows or stops motion. In this lab, students compare the force necessary to move the same object over various surfaces. The relative friction produced by these surfaces can be determined and compared.

Browse friction experiments resources on Teachers Pay Teachers, a marketplace trusted by millions of teachers for original educational resources. Leonardo Da Vinci (1452-1519) was one of the first scholars to study friction systematically. He realized how important friction is for the workings of machines. He focused on all kinds of friction and drew a distinction between sliding and rolling friction.

It involves objects in contact with each other, and it can be either useful or harmful. Friction helps when you want to slow or stop a bicycle, but it is harmful when it causes wear on the parts of a machine. In this activity, you will study the effects of surface smoothness and the nature of materials in contact on sliding friction.
