This resource contains an engaging PowerPoint (23 slides) and accompanying worksheets, some of which have been differentiated to help students of different abilities to take on the task at hand. The lesson begins with the introduction of the term, osmosis, and then students are challenged to use their knowledge of diffusion to write a definition for this method of movement of water molecules. A series of questions which check understanding are included at this early point of the lesson to ensure that the key points are known and any misconceptions are quickly addressed. Students are also challenged with an application question as these can often cause them the most problems. Moving forwards, the rest of the lesson focuses on an osmosis investigation. Scientific skills are tested during a range of tasks as well as numerical skills and guidance is given on how to calculate percentage change. As stated at the top, this lesson has been designed for GCSE-aged students who are studying the AQA GCSE Biology course, but can be used with younger students who are keen to learn about osmosis

This fully-resourced lesson has been designed to cover the content found in specification point 5.1 (Homeostasis) of topic 5 of the AQA GCSE Biology & Combined Science specifications. This resource contains an engaging and detailed PowerPoint (45 slides) and accompanying worksheets The lesson begins by challenging the student’s literacy skills as they are asked to recognise the key term, optimum, from 6 of its’ synonyms. Moving forwards, a range of quiz competitions are used to introduce the term homeostasis and to provide a definition for this key process. Students are given a newspaper article about water and blood glucose so they can recognise 2 conditions which are controlled in the human body. The next part of the lesson looks at the importance of maintaining the levels of water and glucose by considering the medical problems that could arise if they move away from the optimum levels. Students will learn that body temperature is also controlled and links are made to earlier knowledge as they have to explain why an increase in temperature above the set point would be an issue because of the denaturation of enzymes. The rest of the lesson looks at the three parts that are included in all control systems before a final quiz round introduces the receptors, coordination centre and effectors in the control of body temperature. As stated at the top, this lesson has been designed for GCSE-aged students who are studying the AQA GCSE Biology or Combined Science course, but it can be used with A-level students who need to go back over the key points before looking at the process in more detail

The lesson begins with a game of IMPOSSIBLE (shown in the picture) where students are challenged to pick out the names of the 7 structures of the eye which the specification states they have to be able to identify on a diagram. Students are given the functions of the cornea and the sclera to guide them at the start of the labelling task before they have to use their previous knowledge of the nervous system to write a function for the optic nerve. Literacy and numeracy skills are tested throughout the lesson and the next round of the quiz challenges them to use synonyms to recognise the key terms of adaptation and accommodation. Time is taken to focus on the process of accommodation so that students can see how the ciliary muscles and suspensory ligaments interact to change the shape of the lens and allow both near and distant objects to be seen clearly. This takes the lesson nicely into the next section where the conditions of myopia and hyperopia are considered. Again, the students are challenged on their recognition of Biology terminology to spot that these are the medical names for short and long-sightedness. Students are guided through the correction of myopia before being challenged to write a letter to the mother of a girl who suffers from hyperopia, explaining how the lens is used to correct the defect. As stated at the top, this lesson has been designed for GCSE-aged students who are studying the AQA GCSE Biology course, but can be used with younger students who are keen to learn about the eye or with A-level students who need to go back over the key points.

This lesson has been designed to cover the content of specification point 4.1.2.1 (Chromosomes) and 4.1.2.2 (Mitosis and the cell cycle) of the AQA GCSE Biology and Combined Science course. Cell division is a topic which can cause students a number of problems so this lesson has been designed to ensure that the key details are covered and checked constantly. As well as the understanding and previous knowledge checks, quiz competitions are written into the lesson to maintain engagement and motivation. The lesson begins with the introduction of the term cell cycle and students will learn that the cycle consists of three stages. The key details of each of these stages is covered during the main part of the lesson so that students can meet the specification requirements of being able to describe the main events. Time is allotted for discussion to encourage students to converse about important points such as what happens to the replicated chromosomes during mitosis to enable identical daughter cells to be produced. Opportunities are taken to make links to other topics such as animal and plant cells as students are challenged to recall the functions of some sub-cellular structures. The final part of the lesson involves a series of summary questions which challenges the students to not only recall content but also to apply to unfamiliar organisms and it is not until the final question that they will answer a question about the cell cycle in humans.

This lesson has been designed to cover the content of specification point 4.1.1.1 (Eukaryotes and prokaryotes) of the AQA GCSE Biology and Combined Science course. The understanding of this topic is fundamental to a lot of the later topics on the course so time has been taken to ensure that the key details are covered whilst engagement levels are kept high through the range of activities. The lesson begins by asking students to copy a diagram of a bacterial cell from memory before challenging them to recognise anything that is missing so they can discover the lack of the nucleus. Students are introduced to the idea of a prokaryotic cell before important questions are answered such as the fact that the cell still has DNA despite the absence of the nucleus. Key terms such as plasmid are introduced to the students through the use of quiz competitions in an effort to increase the likelihood of these words being remembered. Moving forwards, eukaryotic cells are considered and the common features of both of the cells are discussed and recalled. Finally, students are asked to compare both types of cells in terms of their size before being challenged on a range of mathematical skills in which they have to convert between the units of centimetres, millimetres, micrometres and nanometres.
