Friction - Lesson Plan 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>The lesson plan from The Primary Science Advisory Service Ltd focuses on exploring friction and its effects, tailored for Year 5 students. It begins by defining friction as the resistance that occurs when two surfaces slide against each other, which can cause objects to slow down. The lesson aims to help students understand how friction affects movement and the rate of deceleration. Building on previous knowledge, such as the warming effect of rubbing hands together, the lesson progresses to more complex concepts. It links to the National Curriculum, showing how friction is relevant to other subjects like Design and Technology, where students will create a balloon-powered car, and Maths, through graphing experimental results. Health and safety considerations are highlighted, especially when handling sharp objects like bamboo skewers or when performing demonstrations that involve potential hazards.</p>

<p>The lesson comprises a series of activities, each designed to illustrate different aspects of friction. One demonstration shows how friction between a mug and a handkerchief, as well as between the handkerchief and a table, can be overcome with a swift motion. Another experiment investigates whether mass affects friction by pulling a Tupperware tub across various surfaces and measuring the force required. In the car and ramp activity, students release a toy car down a ramp covered with different materials to observe how surface roughness affects the car's travel distance. Finally, the balloon-powered car activity encourages problem-solving as students construct cars and test how far they travel on different surfaces or with varying masses. Each activity is accompanied by questions to provoke thought and understanding about the principles of friction. The plenary session is an opportunity for students to reflect on what they have learned about friction, its occurrence, and its impact on motion.</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>
