This is a complete lesson covering sections 5.1.2 c, d and e of the OCR chemistry specification- Ka the acid constant and pH. It goes through how to how to calculate Ka and the relationship between Ka and pKa. It also covers the calculation of pH for strong monobasic acids as well as the relationship between pH and the concentration of Hydrogen ions. 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 pair of lessons and a worksheet covering sections 5.1.4 a-i of the OCR Physics specification- the gas laws It covers: The gas laws The ideal gas Kinetic theory The effect of newtons Laws Internal energy PAG 8 The two lessons and the PAG take around 5 hours in total. All answers are included I generally try to reduce copying so other than the worksheet all resources are found in the lesson PPT

A complete lesson covering section 6.2.5 b and c- further organic synthesis. The lesson covers a variety of skills needed for organic synthesis: identifying functional groups Identifying synthetic routes Completing flow charts showing synthetic routes Recalling and using reagents and conditions Drawing reaction mechanisms including curly arrows The lesson is a mixture of student activities and teacher led worked examples All answers included i aim to reduce photocopying so all activities are in the PPT (47 slides in total)
