This is a complete lesson covering points 5.2.2 a-f of the OCR Chemistry specification- Entropy and free energy The less starts by introducing the concept of entropy and the effect that changing state, dissolving and producing a gas have on the value. It then looks at calculating entropy changes.It the looks at Gibbs free energy and how this can be calculated including the difference between endothermic and exothermic reactions. The lesson follows an explicit instruction model with lots of opportunities for i do, we do, you do All answers included I am to reduce photocopying so all activities are within the PPT (30 slides in total)

A complete lesson covering section 6.2.5 a and b of the OCR chemistry specification- chemical analysis using thin layer chromatography and gas chromatography. The lesson starts by recapping some of the analytical techniques introduced in year 12. The lesson then moves on to TLC chromatography and how this can be used. This includes some exam questions and independent tasks The lesson then moves on to looking at gas chromatography again using lots of independent tasks to support understanding I am to reduce photocopying so all activities are in the PPT (37 slides in total)

A complete lesson revising content from AQA trilogy topic B6- Genetics and reproduction. The lesson has been updated to reflect the return to normal exam oprocedures. The old version is inclduded. the lesson covers : Gender determination Genes and DNA Genetic crosses Asexual reproduction Meiosis Vs mitosis Cystic fibrosis Evolution Selective breeding and GM

A complete lesson covering section 6.2.5c of the OCR specification - testing for functional groups and PAG7.3 The lesson starts with reminders of the tests for the main functional groups in the OCR specification. Each one is set out with the same structure- first giving an opportunity for recall before revealing the answer. The lesson then introduces PAG7.3 (you will need to download the full details off the OCR interchange). After the practical there are a series of activities allowing students to apply what they have learned about the tests. These can be done individually or as a class. I am to actively reduce photocopying so all activities are in the PowerPoint (29 slides in total)

This is a complete lesson covering sections 5.2.2 I, j, k and l of the OCR Biology specification- anaerobic respiration and respiratory substrates. It starts by introducing anaerobic respiration in various organisms including lactate fermentation and alcoholic fermentation. It then goes on to look at respiratory substrates and respiratory quotients including their use and calculation. There are some summary questions to check for understanding before looking at respirometers. The lesson includes a starter, full notes, various student led activities and a differentiated summary at the end. All answers are included. I actively try to reduce photocopying, so all of the lesson resources are within the PowerPoint rather than as extra sheets.

A complete lesson covering section 5.2.1 and 5.2.2 of the OCR Physics specification- circular motion It covers circular motion, centripetal force and acceleration and all associated equations. The lesson closes with a practical investigating and analysing circular motion Lots of students activities included All activities in PPT as I aim to reduce photos=copying
