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 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.
