Light - Refraction - Classroom, Distance and Blended Learning KS3

The two packs in this resource allow the same lesson on refraction to be taught to students whether they are in a classroom or distance learning at home. It facilitates hybrid learning and provides equality of opportunity for students who are unable to attend school.

The classroom resource consists of an animated 29 slide PowerPoint and 15 varied and exciting printables including a foldable, cut-and-stick and progress check. The one-page flowchart lesson plan shows where choices can be made between the printables so that the teacher can select the activities to suit the exact needs of their class.

The distance learning pack consists of a 64 slide animated PowerPoint which, not only teaches the science but also how to gain maximum benefit from distance learning. The PowerPoint has been designed to replace the teacher by providing structure, sequence, knowledge and answers. Additional worksheets, cut-outs, foldable and progress check provide a familiar medium for students to develop and test their knowledge, continue to develop their literacy skills and use their creativity to organise their learning and assess their progress. These can be printed off by the student or provided by school. There is also a short digital test/homework which can be returned to the teacher. A shortened photocopiable PDF of the PowerPoint is provided to circulate to those pupils without computers.

What’s Covered

• 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.
