Transparency and Magnetism - Presentation is part of the lesson Transparency and Magnetism    Students will learn about transparency and magnetism as part of their learning about properties and changes of materials, as specified by the national curriculum in England: science programmes of study.

<p>In an engaging Chemistry lesson on the Properties and Changes of Materials, students explore the concepts of transparency and magnetism. They are tasked with classifying materials as transparent, translucent, or opaque based on how they interact with light. Transparent materials allow all light to pass through, making them see-through, while translucent materials let some light through but not enough to see clearly, and opaque materials block all light, preventing any visibility through them. The lesson also delves into the fascinating world of magnetism, where students learn to identify materials that are attracted to magnets, focusing on the magnetic properties of metals such as iron, nickel, and cobalt, while noting that not all metals are magnetic.</p>

<p>The lesson includes a practical investigation where students use a torch to classify various materials according to their light transmission properties. They also conduct experiments with magnets to differentiate between magnetic and non-magnetic materials. Moreover, the lesson introduces the concept of smart glass, an innovative material that can adjust its transparency in response to light levels, offering a solution to the problem of excessive sunlight in south-facing windows. By the end of the lesson, students are expected to understand the differences between transparent, translucent, and opaque materials, identify which materials are magnetic, and appreciate the practical applications of these properties in everyday life.</p>

<p>This lesson focuses on comparing and grouping everyday materials based on their properties of transparency and response to magnets. The objectives are to classify materials as transparent, translucent or opaque, and to classify materials based on whether they are attracted to magnets.</p> <h2>Previous Learning</h2> <p>The students have previously learned about everyday materials, the uses of everyday materials, rocks, forces and magnets, light, and states of matter. In Year 1, they have identified and named various everyday materials. In Year 2, they have found out how the shapes of solid objects can be changed by squashing, bending, twisting and stretching. In Year 3, they have compared and grouped rocks and everyday materials based on their appearance and physical properties and learned about light and shadows. In Year 4, they have compared and grouped materials based on whether they are solids, liquids, or gases.</p> <h2>Cross-Curricular Links</h2> <ul> <li>History: Pupils could learn about ancient cultures navigating the seas using lodestone.</li> <li>DT: Pupils could learn about soda glass manufacturing.</li> <li>Art: Pupils could learn about the meaning of 'pentimento' and its impact on galleries.</li> </ul> <h2>Misconceptions and Corrections</h2> <ul> <li>Transparent objects do not cast shadows - All objects, regardless of material, cast shadows to a greater or lesser degree.</li> <li>All metals are attracted to magnets - Only certain metals are attracted to magnets.</li> <li>All non-metals do not attract magnets - Liquid oxygen is attracted to magnets.</li> </ul> <h2>Important Lesson Guidance</h2> <p>The teacher is encouraged to provide a variety of materials for pupils to handle during the lesson. </p> <h2>Activity: Transparency Investigation</h2> <p>The students will work in groups of 4 and investigate the transparency of various materials using torches. They will hold the object up, note the material it is made of, and one student will stand on either side of the object. One student will hold the torch close to the object and turn it on, and the other student will observe if they can see all, some, or none of the light. They will repeat the process with various materials and use their results to classify the materials as transparent, translucent, or opaque. The goal is to obtain 20 results.</p> <h2>Science Explained</h2> <ul> <li>Objects are either transparent, translucent, or opaque.</li> <li>Opaque objects reflect light.</li> <li>Different types of the same material can have varying transparency.</li> <li>Gases tend to be transparent.</li> </ul>
