Friction - Self Assessment 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>Understanding the concept of friction is essential in the study of physics, and self-assessment is a valuable tool for students to gauge their grasp of the subject. Friction is the force that arises when two surfaces move against each other, and it is an important phenomenon that students should be able to acknowledge. Recognising that friction plays a significant role in decelerating objects is another key learning outcome. This understanding is fundamental to comprehending the practical implications of friction in everyday life, from the brakes in a car to the grip of shoes on the pavement.</p>

<p>Moreover, being able to describe the various factors that influence friction is a further step in a student's learning journey. Factors such as the texture of the surfaces in contact, the weight of the objects, and whether a lubricant is present can all affect the amount of friction experienced. Teachers play a crucial role in guiding students through these concepts, providing feedback, and clarifying any misconceptions. A student's ability to articulate these principles and to reflect on their teacher's feedback demonstrates a solid understanding of how friction impacts the world around us.</p>

<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>
