Have the students jump (motion) and count to ten as they do so, i.e. Show the class various different surfaces, such as felt, wood, foil, or plastic, and ask the students to predict which surfaces provide the least or greatest amounts of friction. Test which surfaces create more friction, see how strong friction is, learn how to reduce friction, and even discover the side effects of friction. 12.2 Factors affecting Friction Activity 12.2 Tie a string ar ound a brick. Back to Science for Kids They are also writing about friction in a way that creates an opportunity to address SP-8, by obtaining observational data and communicating that to others through the creation of a definition of friction. Then, in the associated activity, Sliding and Stuttering, they work in teams to use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. Question 2. Friction. Friction is a force between two surfaces that are sliding, or trying to slide, across each other. What is the force of friction? Which surface slows a vehicle down more - vinyl, wood, carpet or ice?

They can do this as an entire class or in pairs where one partner jumps and the other counts each jump (up to 10 - or whatever number the teacher decides on). Friction / class 8 ncert / science / physics 1. Friction. 7. In which of the following activities is friction useful? Filed Under: Class 8, Friction Tagged With: Friction can be reduced by applying lubricants, Friction can be reduced by making the surface smooth by polishing, Friction can be reduced by using ball bearing, Friction can be reduced by using wheels to move objects, lubricants, lubrication. About this quiz: All the questions on this quiz are based on information that can be found at Physics: Friction. Explain why sliding friction is less than static friction. MS-PS2-2 is addresses through this activity because students are making sense of the forces that can affect an object's motion. Sliding friction comes with play when an object is sliding over another. Question 8: A blacksmith hammers a hot piece of iron while making a tool. The force of friction acts between the object and the surface. 1. Friction (Class 8, Science, CBSE, NCERT) - lesson plan ideas from Spiral. 5. 9. Friction . Fluid friction describes the friction between layers of a viscous fluid that are moving relative to each other. Correct Option is : 3. If you want to further engage your students on friction topics, you can use the provided class activities and games. 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 friction experiments for all ages.
