Starter: Retrieval starter, based on prior knowledge about animal and plant cells Main: explaination of how to convert between common units used in biology Differentiated task to convert between units -explaination of how to use standard form questions to practice on standard form microscope questions to explain examples differentiated magnfication worksheet Plenary: plenary grid with questions from this lesson and based on animal and plant cells. to be done individually or as a group

This lesson is suitable for the AQA GCSE Biology and AQA Combined Science: Trilogy course looking at magnification and how to calculate the magnification and/or length of a cell. It also aims to cover an introduction to Prefixes and Standard Form, as these are also asked of students in both Higher Tier and Foundation Tier exams (as show in the Independent Practice question section of this lesson). The “More Magnification Calculations” are for students to have more practice in using the magnification calculation. I would recommend printing the first page out to be used as a handout to students. When using this resource I would suggest that: The ‘Knowledge Checks’ are completed on Mini White Boards. The re-teach slide is only there in case it is needed from the ‘Knowledge Check’ - hence, can be skipped over if not needed. The ‘Check for Understanding’ questions are also completed on Mini White Boards. The ‘Independent Practice’ questions are completed in student exercise books - with the students working silently and independently.

Complete No-Prep lesson with exam questions, tasks and answers on Concave Lenses, Magnification and Magnifying Glasses (Convex Lenses) for AQA GCSE (9-1) Physics. This lesson covers part of GCSE Physics 4.6.2.5, with the remainder of this exam spec section in the previous lesson (“Convex Lenses”). As a Secondary Science teacher, Deputy Headteacher, writer and examiner for many years I make high quality no-prep lessons so busy teachers can teach outstanding lessons without spending hours planning. This high quality lesson includes explanations, different types of in-lesson assessment (all with answers) and unique exam questions. My lessons are ideal for non-Physicists - as a Biologist who retrained as a Physics teacher I know how to take learners on a journey that builds up their understanding step by step, while still going into a lot of depth. The preview video shows a representative sample of slides from the resource so that you get a good idea of what it includes before you buy. What’s Included: • Teaching notes • Starter / Do Now Activity • Explanation slides in “chunked” sections with animated diagrams. • Worked examples of calculations / questions. • Multiple questions in different question styles and difficulties - no need for worksheets. Each “chunked” explanation section typically includes a set of “learning check / quick questions” followed by a set of in-depth questions on the learning from that “chunk” of the lesson. All questions have answers. • Exam-style questions on the whole lesson at the end of the lesson- these are unique, based on real exam questions but not just copied from exam boards. • Answers for all questions • All easily editable to adapt to your teaching or to use in existing lessons. • Slightly humorous, at points, if you like that sort of thing. The lesson was written for AQA GCSE Science / Physics but is very likely to be applicable to other exam specifications.

This is a Year 10 lesson created for SEN/LAP pupils The focus is only on how to calculate actual size from image size and magnification. There is no triangle or rearranging equations. Included: Starter - scientific drawing of a white blood cell Recap - how to calculate total magnification Content and presentation - how to calculate actual size, examples given: an Ant and Leonardo DiCaprio Independent task 1 - actual size table completion and a question Independent task 2 - using rulers to calculate actual size from images of 8 cells Plenary - calculation actual size question 2 x worksheets unblurred when bought Answers included for independent task 1. Not for task 2 as this is dependent on how you print. The lines for where to place the ruler are included.

Calculating Magnification , KS4 Well Structured lesson Just download and teach

Magnification calculation questions with colour code scaffolding to reduce cognitive load. Contains questions to calculate actual size and to calculate magnification.

The lesson is a maths for biology focused lesson which involved a series of calculations for magnification (3 levels of differentiation) followed by a hinge point question leading into a series of calculations on scale and perceived size. The demonstrate activity is a student choice of difficulty to solve a biological problem. The lesson concluded with an exit ticket.

This lesson was written for my lower ability yr9 science class and was designed for a 60 minute lesson for students who struggle with writing. The lesson can be printed out so that they can work at their own pace if necessary. There is no requirement for IT and the lesson could be used as cover if a specialist science teacher isn’t available. The lesson begins with a Do Now or a Settler Activity which is a cryptogram about microscopes. There is then a comprehension / literacy exercise that involves reading text about microscopes and then arranging facts about light and electron microscopes. There is some numeracy work where pupils learn to calculate magnification and practice calculating the size of images seen using microscopes and the lesson ends with a plenary task where pupils write about what they’ve learned in the lesson.
