Water Resistance - Results Tables is part of the lesson Water Resistance    Students will learn about water resistance as part of their learning about forces, as specified by the national curriculum in England: science programmes of study.

<p>The investigation into the impact of boat size on water resistance is meticulously recorded in a series of results tables. Each table lists various boat shapes, with corresponding measurements of water resistance in Newtons (N) taken over three attempts. The average resistance is then calculated to provide a clear comparison between the different designs. Boat shapes such as wide, narrow, sharp point, shallow point, wide wedge, and narrow wedge are all examined to determine how their size affects the water resistance they experience.</p>

<p>Another aspect of the study focuses on submarine shapes and their ability to dive quickly. A comparative table showcases matchups between two different submarine shapes, with one being declared the winner in terms of diving speed. Shapes compared include large versus small discs, arrowhead against long tube, bullet versus short tube, large cube against small cube, and large sphere versus small sphere. The outcomes of these comparisons are recorded, revealing which submarine shape is superior in speed when it comes to diving. This data provides valuable insights into the design considerations for marine vehicles in relation to their performance in water.</p>

Water Resistance - Presentation

<p>This lesson focuses on the concept of water resistance, its effects on moving objects, and ways to reduce it. Students will learn about the forces that act between moving surfaces and how they affect the movement of objects. The students will be introduced to the influential scientists who have studied water resistance and friction, and will be taught about the differences between water resistance and friction. </p> <p>The lesson is divided into three activities: making and testing boats, watercraft shape research, and the quickest submarine. In the first activity, students will create different boat shapes and measure the water resistance using a force meter. In the second activity, students will research the shapes of different watercraft and compare them with ancient and modern watercraft. In the third activity, students will create submarines and compare their speeds. </p> <h2>Keywords</h2> <ul> <li>Friction</li> <li>Water Resistance</li> <li>Surface Area</li> <li>Decelerate</li> <li>Water Particles</li> <li>Drag</li> <li>Float</li> <li>Sink</li> </ul> <h2>Misconceptions</h2> <ul> <li>Water Resistance is not friction</li> <li>There is no water resistance for floating objects</li> </ul> <p>It is important to note that water resistance is a type of friction, where the particles of an object strike water particles as it moves through air. Also, objects in contact with water still experience water resistance.</p> <h2>Important Lesson Guidance</h2> <p>In this lesson, students will be conducting experiments with water troughs, so it is important to have plenty of paper towels ready. The cleanup procedure for the water trough experiments is described in the lesson plan, but if students forget to place their troughs on the corner of the table, they will need to use a jug as a scoop instead.</p>
