A full lesson covering section 4.1.1n the benefits and risks of the use of antibiotics. This includes the discovery of antibiotics by Fleming in 1928 as well the development of antibiotics as a treatment in WW2. It also covers the risks associated with the development of antibiotic resistance and ways in which this might be prevented The lesson includes a starter, full notes, multiple independent student learning activities and a fully differentiated summary at the end.

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 revision lesson covering both adaptation and competition. It reminds students what animals and plants compete for and how they are adapted. It focuses on the importance of understanding why the adaptation is helpful. The lesson includes lot of students activities and exam practice All answers included

A full lesson covering 3.1.3 c of the OCR specification- Transpiration. Covers transpiration, the factors affecting the rate of transpiration, the use of potometers and the content required for PAG5.3 including how to calculate the volume of water lost and the transpiration rate.

This is a complete lesson covering sections 5.2.1 a, b and c of the OCR Biology specification- chloroplasts and chlorophyll. It starts by looking at the compensation point and offering students the chance to analyse some data. It then looks at chloroplasts and how they are adapted to their role before discussing the structure of chlorophyll. The lesson then looks at light absorption spectra and provides data for students to draw a graph of the absorption spectra for chlorophyll a and b. The lesson closes by looking at photosystems and introducing their role in the light dependent reaction. The lesson does not cover chemiosmosis. I cover this during respiration.
