Friction - Teacher Explanation is part of the lesson Friction    Students will learn about friction as part of their learning about forces, as specified by the national curriculum in England: science programmes of study.

<p>Welcome to lesson 5.2 on Friction, part of the Year 5 Forces Unit in the National Curriculum. In this lesson, pupils will explore the effects of various forces such as air resistance, water resistance, and friction, specifically focusing on how they act between moving surfaces. It is important to note that for safety reasons, pupils will be handling bamboo skewers and should be cautious of the pointed ends. Additionally, a ceramic mug will be used in one of the activities, and if it breaks, it is crucial to clean up the fragments immediately and vacuum the area. Prior to the lesson, some preparation is necessary, including using a hammer and nail, which pupils should not handle during the lesson. This session is not only informative but also offers cross-curricular links to Design and Technology (DT) and Mathematics, where pupils can graph their experimental results.</p>

<p>The lesson includes a demonstration familiar to many, where a magician yanks a tablecloth, leaving the items on the table undisturbed. This serves as a friction experiment, and pupils will use a cloth and mug to understand the concept better. They will also engage in an activity to investigate how mass affects friction by dragging a container across different surfaces and measuring the force required with a Newton meter. The experiment will be repeated with increasing amounts of mass to observe the effects on friction. Finally, pupils will build and test a balloon-powered car, which will further illustrate the principles of friction as they observe how different surfaces and weights affect the car's movement. This hands-on activity not only reinforces the scientific concepts but also encourages problem-solving and creative thinking.</p>

Friction - Self Assessment

<p>In this lesson, students will learn about the effects of friction on moving surfaces. The objective of this lesson is for students to be able to identify that friction occurs when two surfaces slide against each other, understand that friction slows objects down, and describe the relationship between the amount of friction and the rate of deceleration. This lesson aligns with the Year 3 science curriculum on Forces and Magnets and has cross-curricular links to Design and Technology and Mathematics. </p> <p>Students will be introduced to the science behind friction through a teacher demonstration of the "Handkerchief and the Cup" activity. They will then participate in the "Does Mass Affect Friction?" activity where they will test the amount of friction on different surfaces with varying amounts of mass. The results of this experiment can be graphed for mathematical analysis. </p> <h2>Misconceptions and Corrections</h2> <p>It is important to note that students may have misconceptions about friction. Some students may think that lubricants eliminate friction, when in reality, they only reduce friction. Additionally, students may believe that friction is not useful when in fact, it is essential in slowing down machines. Finally, students may believe that smooth surfaces have no friction when all materials show friction to a certain extent.</p> <h2>Keywords</h2> <ul> <li>Friction</li> <li>Decelerate</li> <li>Smooth</li> <li>Rough</li> <li>Surface</li> </ul> <h2>Influential Scientists</h2> <p>This lesson highlights the work of several influential scientists in the field of friction including Leonardo da Vinci, Guillaume Amontons, Charles Augustin de Coulomb, Charles Hatcbett, Theodor Reye, and David Tabor.</p> <h2>Important Lesson Guidance</h2> <p>It is important to note that before the lesson, you will need to collect 32 plastic bottle caps and punch holes in the center of each cap. The "Does Mass Affect Friction?" activity requires materials such as Tupperware tubs, masses, string, force meters, a 100ml measuring cylinder, and aluminium foil. The experiment is performed in groups of four and the results can be recorded in a table for analysis. It is important to keep the balloon cars for Lesson 5.3. </p>
