two worksheets, one for Biology students and one for Higher tier combined students, differentiated to 2 levels (hence 4 worksheets in total). AQA references: Biology: 4.5.2.4 (temperature) and 4.5.3.3 (water level control)/combined: 4.5.3.7 (thyroxine) and 4.5.3.2 (blood glucose) Edexcel references: Biology: 7.10B (temperature and water level control)/ combined: 7.3 (thyroxine) and 7.14 and 7.14 (blood glucose) Useful for consolidation of the term 'negative feedback' and revision of examples encountered in the course. Also has a real life example (thermostat) and relates negative feedback to their own feelings for re-enforcement. Model answers included.

This is a full lesson with prescriptive instructions, aimed at AQA and Edexcel specifications (references included), but would work for other boards. The main objectives are to research the information and to practice use of command words and general exam technique. The students are given exam style questions and in groups, are to research the information required to produce 'perfect answers' They then assess the answers given to different questions by others and make adjustments to the answers, as necessary. Exam questions are tailored to ability and there is a focus throughout on exam command words. The lesson ends with the students attempting to assign a grade to the exam questions they have been exposed to during the lesson and there is a suggested homework, where the students produce follow-up notes. Suggested 'indicative content' is included in the teacher notes, but are intended to guide the teacher, rather than for the students to compare given answers with. However, this could be used for this purpose, if you prefer. Also included is a slide that gives notes needed to answer the questions, if you are a bookless school. This may be projected up, depending on the layout of your classroom, or printed.

Developed for the new specification AQA exam board, but would work for other exam boards. Higher tier lesson are also available (which has the added lesson for fertility treatment) The menstrual cycle lesson starts with 'menst side story' where the students complete a table and then go on to make a cartoon based on knowledge gained. The second lesson requires the students to take on the role of the hormones (or other characters) to develop their peer teaching skills. Resources are fully differentiated and there is opportunity to explore exam command words. Suggested home works are included as well as required resources and potential alternative activities.

Based on the AQA specification (new specification), but would work for other exam boards. The lessons start with 'menst side story' (embedded in the PowerPoint) where the hormones play characters and the students answer questions based on the story. Students go on to build a model of the graph of the different hormone. In the contraception lesson, the students assume the roles of the hormones (and other characters) to explain how a contraceptive method works as a peer teaching exercise. Fertility treatment lesson is a debate lesson. All lessons are fully differentiated to three levels of difficulty and include opportunities to explore exam command words. Suggested home works are included, as well as information of resources required, specification references and alternative approaches, where appropriate.

for a medium to low ability class. the one leabelled 'les' just has fewer cells in it for lower ability. This could be differentiated further by taking out other cells. I reckonit would be good for a revision lesson or a homework. The students can sort the labels into at table, labelled &'cell&'; (picture), 'function&' and &';adaptations'.
