Light - Reflection, Refraction and Lenses - 3 Fully Resourced Lessons Plus Smart Board Bingo KS3

Three comprehensive and fully resourced lessons on refraction, reflection and lenses for middle school plus an enjoyable and challenging escape room lesson to consolidate learning. Each teaching pack contains at least thirteen resources and it is intended that the teacher uses them to build their own unique lesson to take account of student ability and time available. Literacy, oracy, self-assessment and peer assessment are all built in to the resources. These features are clearly marked on the comprehensive one-page flow chart lesson plan which shows where the logical choices between resources can be made. There are three differentiated and engaging homeworks which can also be used as classwork if so desired. The game is closely related to the topic content and reinforces learning. Students must work their way through the clues to find the code to a combination lock on the school storeroom where Molly, a pupil’s dog, has been accidentally locked after following the child to school and while the school secretary phones home. <br> **What’s Covered** <br> **Reflection** * Transparent, translucent and opaque materials * Luminous and non-luminous objects * Labelling the incident and reflected rays, the angles of incidence and reflection, the normal and the point of incidence * Virtual experiment to prove i = r * Ray diagram showing how the eye sees an image in a plane mirror * The image formed in a plane mirror is upright, virtual (appears to be formed behind the mirror) laterally inverted, the same size as the object and as far behind the mirror as the object is in front. * Ray diagram showing how the eye sees an image in a periscope * Specular and diffuse images <br> **Refraction** * The more dense the medium the slower the speed of light. * When light travels from a less dense medium to a more dense medium it is bent towards the normal. * When light travels from a more dense medium to a less dense medium it is bent away from the normal. * Light hitting a boundary at 900 is not refracted. * Light is not refracted at a curved boundary. * Complete ray diagrams showing refraction. * Design an experiment and results table to investigate refraction through a semi - circular glass block * Why lightning is seen before thunder is heard when a cloud discharges. * Real and apparent depth <br> **Lenses** * Ray diagrams showing refraction in a concave and convex lens. * Convex lenses are used in magnifying glasses, telescopes and spectacles to correct long sight. * Concave lenses are used in lasers, flashlights, peepholes and spectacles to correct short sight. * Label the following structures on a diagram of the eye; retina; ciliary muscle; iris; pupil; lens; suspensory ligament; optic nerve. * Draw ray diagrams and explain how the eye sees distant and close objects. * Draw ray diagrams and explain how lenses are used to correct long and short sight. * Draw diagrams and explain how the iris controls the size of the pupil and therefore the amount of light which enters the eye. * Draw a ray diagram of the pinhole camera, know that the image is inverted sand diminished, moving the object closer enlarges the image and multiple pinholes produce multiple images * Label a diagram of the camera and explain how a picture is taken. * Explain the differences and similarities between the eye, the pinhole camera and the camera. <br> **What’s Included for Each Lesson** * Animated PowerPoint for teaching with exit ticket quiz * Flip it (pupil writes questions to given answers) * Anticipation Guides (combined starter and plenary) * Foldable * Cut and stick activity. * Worksheet to support the PowerPoint * Fact sheet * Homework plus answers * Fact share worksheet * Pupil progress self-assessment checklist * Exit Ticket * Suggested lesson plan showing choices possible between resources <br> **Escape Room** * PowerPoint – scene setting and instructions (sound effects and built-in timer); * crossword; * word search; * dominoes activity; * worksheet; * code breaker sheet; * answers; * lesson plan. **For more high quality resources visit:** [Elf Off the Shelf Resources](https://www.tes.com/teaching-resources/shop/penyrheol1)
