This PowerPoint explains visually how substrate concentration affects the rate of enzyme controlled reactions. Uses graphs and animations. At the end the slides help students to distinguish between DESCRIBING the effects and EXPLAINING the effects. This uses the key phrases and words that examiners are looking for in students answers in examinations (from AQA markschemes).

This is a very valuable revision resource for A level Biology students (especially AQA). I have collated all key phrases from mark schemes for all main topics. This will allow students to focus on picking up marks on exam questions, once they have revised a topic. Used very successfully with many A level students in the past.

A very useful document to give to students when revising, in order to maximise the number of marks they obtain in longer answer questions (4-6 marks). I have also used very successfully in my teaching when writing learning objectives and teaching language in exam answers. Used for AQA A level Biology

This is for A level specifications (not AS). Help with long answers in A2 topic areas (4-6 marks). Great for student revision or to use in lesson planning to establish correct use of terms and phrases that get marks in exam papers.

For A level Biology (AQA). Slide show has differentiated learning objectives. Interactive slides. Links to video clips. Feel free to use/modify for your own use. Might save you time
