A complete lesson covering sections 5.5.3 d-o of the OCR Physics specification- the big bang theory, the cosmological principle, the Doppler effect and red shift. The lesson starts by covering the Doppler effect in sound and how this also applies to red shift in light. It the covers how this and CMBR act as evidence for the origins of the universe in the big bang. It covers the Hubble constant, how its value is not exact and how it can be sued to estimate the age of the universe. The lesson closes by looking at the events immediately following the big bang and how the universe is believed to have changed. The lesson includes lots of calculations and multiple student activities All answers are provided I aim tor educe photocopying so all resources are within the PPT- a total of 50 slides

A pair of lessons covering sections 5.2.3 f-i of the OCR Chemistry specification- electrode potentials The first lesson starts by looking at what half-cells are, how they are formed and the importance of salt bridges. It also covers how they can be used to measure standard electrode potentials. The lesson then covers half equations and using them to calculate the voltage of a electrochemical cell. The second lesson looks at the feasibility of reactions and how they can be predicted using half-cells. It also looks at the limitations of using electrode potentials to predict reactions Both lessons include lots of student independent work tasks and all answers are included I am to reduce photocopying so all activties are in the PPTs (30 slides and 25 slides each)

A complete lesson covering section 5.1.1 b and c of the OCR Biology specification- how gene linkage and epistasis can affect the phenotypic ratios and how this can be investigated using Chi square. The lesson starts by introducing sex linkage and then includes some examples of genetic crosses involving colour blindness. It then looks at autosomal linkage again using example crosses to support. The lesson the goes on to look at both recessive and dominant epistasis again using lots of examples to support understanding. The lesson closes by introducing the Chi square test As well as the examples the lesson includes lots of exam questions to show how the skills could be assessed I aim to reduce photocopying so all resources are in the PPT (62 slides in total)

A full lesson covering section 6.2.4 a-d of the OCR Chemistry specification- making carbon-carbon bonds. The lesson starts by looking at why we need to form new carbon-carbon bonds. It then looks at the reactions with haloalkanes and acyl chlorides and the reaction mechanisms behind both. The lesson then looks at the reactions of the nitriles and how they can be used in organic synthesis. The final part of the lesson looks at the reactions with benzene and how additional side chains can be added. There are lots of student independent tasks and all answers are provided I aim to reduce photocopying so all activities are within the PPT (32 slides in total)

A complete revision lesson covering section 6.5.1-3 of the AQA trilogy course- forces. It covers forces and their interactions, work done and energy transfer and elasticity. The lesson includes a variety of student led activities, retrieval practice and exam questions All answers provided

A complete lesson covering how to calculate bond energies. This lesson would support both the trilogy GCSE and the separate Chemistry course. The lesson starts with a retrieval starter covering a variety of topics form molecules 1-4 with answers It then recaps endo and exothermic reactions with examples including a video It then covers what is meant by a bond energy using a variety of examples. Students then work through some examples The lesson then moves onto calculating overall energy changes in reactions before going through some examples. There are then some independent examples for students to work through with answers The lesson finishes with some exam question examples All resources provided

A complete lesson covering the structure and function of digestive enzymes from AQA Biology and Trilogy B2- Organisation. It starts with a retrieval starter covering content from B1 and earlier in B2 It then goes over enzymes, their digestive function and the lock and key mechanism. This is then recorded through an information hunt (sheet and questions included). Answers provided. The lesson then looks at human digestive enzymes with a summary table to complete. This is then re-caped trjough 9 quick questions There are then a series of exam questions to cover the content from earlier in the lesson. Answers included The final activity is an example 6 mark question with mark scheme All required resources are in the PPT or as separate files
