OCR A Level Biology A lesson on Antibiotics. This is one of thirteen lessons to meet the specification points for 4.1.1 Communicable Diseases, disease prevention and the immune system. Specification points: 4.1.1 (n) Objectives for this lesson: • Recall the history of penicillin. • Describe how antibiotics work to manage bacterial infection. • Evaluate the benefits and risks of using antibiotics to manage bacterial infections. This lesson includes some articles for students to read and draw information from so students can develop their research and interpretation skills. You will need to download the articles yourself due to copyright. I found them easily on a basic google search. Check out my other lessons and the accompanying workbook with exam questions (and answer booklet included). Please leave a review.

I created this worksheet as a support sheet for students struggling with drawing Punnett squares in the genetics topic. This worksheet is best printed off on A3 and works to walk students through the steps involved in determining the alleles of the parents and creating a Punnett square to determine the probability of certain outcomes. The layout is in a style that allows students to easily follow the process. Have used a similiar format in the past on calculation style questions in physics and drawing ionic bonds in chemistry and students loved it! I have also included the answer sheet to go with it.

Complete lesson and worksheet on Energy and Power with worked examples and calculations. Lesson will take between 1-2 lessons depending on ability of group. The lesson works through what is power, then on to changing between units with some practice questions before moving onto the Power equations and practicing using them to calculate energy, power and time. Questions increase in difficulty with more longer questions later on. All answers are included to allow students to self assess. The lesson then goes on to looking at how to calculate cost of electricity. Hope you like it. If so, please leave a review.

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.
