KS3 Lesson on Sound Waves and Speed of Sound, designed to go with the new Activate scheme. However, it is a great introduction/recap to waves and more specifically sound waves. Differentiated questions and an extension task moving into echoes and sound for higher ability students. Some great opportunities for discussion around what sound can travel through and why, linking to particle diagrams. Only equipment needed to support this lesson is a slinky to use to demonstrate the different types of waves. If you like this lesson, please check out my other lessons and leave a review. Thanks.

Complete lesson on Reflection, designed for the new Activate Scheme but can be used for another syllabus’ as well. Includes various tasks, a practical and discussion. All answers are provided on the slides so students can self/peer assess. There are differentiated tasks and questions. There is a practical requiring light ray boxes, mirrors and protractors for students to investigate what the Law of Reflection might be and to draw their own conclusions before revealing the Law to them. Included in this lesson pack is a Code breaker starter, instruction sheet for students to use as a checklist during the practical to encourage students to follow all instructions in a method, an investigation template for the lower ability students with the incident rays already drawn on and a differentiated worksheet with questions on Reflection and using the Law of Reflection. Check out my other resources and if you like this lesson, please leave a review.

KS3 lesson on Genetic modification, looking at what it is, some examples and then discussion on what the problems could potentially be with GMOs. Lesson includes video, discussion, questions and activity where students need to create a cartoon strip on how GMO are created. If you would like to use an alternative activity, you could get students researching and writing a newspaper article on GM crops and the advantages and disadvantages. This would however, require a second lesson with access to computers/GM research. Please leave a review and check out my other resources. Thanks
