In the majority of my A-level lessons the beginning portion of the lesson is mainly teacher-led, where students are expected to take notes onto a handout/in their books. This is then mixed in with student-led activities, as well as questions and exam prep. You will find some of my slides have blank spaces for you to add more detail/descriptions/explanations. If you look at the ‘Notes’ section underneath each of these slides, you will find additional content which you can add in as you teach! This lesson on the human immunodeficiency virus begins with a starter discussion on immunity and vaccination. Students should discuss the features of a successful vaccination program, and why vaccination cannot often eliminate a disease. Students are then introduced to the structure of HIV and its function as a retrovirus. To explain the infection process students will watch a short video while answering questions in their books. Answers are available on the following slide for self-assessment. The next task is a worksheet for students to label and correctly describe each stage of HIV infection and replication. They can self-asses to the next slide. Students will then discuss the process by which HIV causes the symptoms of AIDS. The following slides explain the function of antibiotics and explain why these are not suitable for treating viruses. In order to introduce the ELISA test, students will watch two short animations and answer questions in their books. Answers are on the following slide for self-assessment. They should take thorough notes in their book, on two diagrams of indirect and direct ELISA. The plenary is to write a tweet demonstrating their learning, including #keywords!

This lesson begins with an introduction to lipids, including a description of the structure of lipids as well as the importance and roles of lipids in the human body. Students are then introduced (or reminded if taking A-level Chemistry) of the full displayed chemical formula and shorthand formula of a fatty acid, the example given is butanoic acid. Students are now shown the displayed chemical formula of glycerol next to the fatty acid formula, and are asked to use their mino whiteboards to show how a condensation reaction could occur between the two molecules. Once students have had a go, the answers are revealed and students can note down the chemical structure of the triglyceride molecule which results. Students are now shown the difference between a saturated and unsaturated fatty acid, the next activity involves students reading information posters about saturated fats, unsaturated fats, cholesterol and phospholipids. They will need to use these information posters to complete a worksheet. Lastly, students will be shown the foot test for lipids and then be given a set of exam questions on this topic. This will then be self-assessed using the mark scheme provided. The plenary question requires students to describe the difference between saturated and unsaturated fats. All resources are included.

This lesson begins with an introduction to proteins, the importance of such molecules in the human body as well as the general structural formula of an amino acid. Students are then shown the structural formula of two amino acids - glycine and alanine - and are asked to used their mini whiteboards to show how a condensation reaction could occur between the two molecules to form a peptide bond. There work can then be checked against the answer provided on the PowerPoint. Over the course of the next few slides, you can run through the main principles of the formation of a protein from the primary -> secondary -> tertiary -> quaternary structure. As students listen to the main principles, they can write these down onto their ‘Protein Summary Sheet’ - provided. Students will then be given a worksheet which shows an image/description of a protein as one of the four levels of protein formation, students have to identify which level it is at (primary, secondary, tertiary, quaternary). Once complete, students can self-assess their work using the answers provided on the PowerPoint. Students will now be introduced to the Biuret test for proteins, which they will need to be able to recite as well as give details of a positve/negative result. The last activity is a past-paper question to test students knowledge of what has been learned this lesson, which can be self-assessed using the mark scheme provided. The plenary requires students to write a twitter message to outline what they have learned this lesson, including #keywords. All resources are included.

This lesson in exchange systems begins by asking students to think of example of exchange systems and the substances which would need to be exchanged. The next slide demonstrates the differences in exchange process for single and multicellular organisms. Notes are available under the slide for discussion. Using the pictures on the slides, students will then identify some examples of substances that need to be interchanged between a living organism and its environment. Those images are then ordered specifically on the next slide to demonstrate SA and body size. If multicellular organisms relied on diffusion, they would die, so they have evolved in other ways! Students should identify these evolved features in their next task. They will fill a table out to explain how each feature functions to help organisms exchange the substances they need. They should be able to identify why multicellular organisms need specialised exchange surfaces or systems. The next slides explain Fick’s Law and define important terms before asking students to calculate the surface area of cells. Answers for self-assessment are on the following slide. Students will then complete lab task CP8 to engage with the effect of SA:V ratio on the rate of diffusion. Materials and method are explained on the slides. Exam-style summary questions are included to consolidate the lab task with lecture notes, and answers for self-assessment are on the following slide. As a plenary, students will spend 60 seconds speaking with the person next to them about what they learned from the lesson over all. All resources are included.

This lesson begins by reminding students of the four general things that need to be exchanged between an organism and their environment and the three factors which may affect the rate of diffusion. This discussion leads into the first few slides which explain how an organism like an amoeba gets the substances it needs. A worksheet is included for this lesson for students to complete as they take notes throughout. An amoeba is used as an example of a unicellular organism, which is then compared to insects. The following slides explain the basic form and function of insects, then the process by which they exchange water and O2. Students should take thorough notes on the spiracle, trachea and tracheoles in their books. The slides in this lesson are lecture based and very detailed, students will want to be sure they have a good understanding of the three ways that respiratory gasses move in and out of the tracheal system. The slides explain that gasses move along a diffusion gradient, through mass transport, and as the tracheoles fill with water. A quick check of exam-style questions and mark scheme follows to help students assess their learning. The plenary task is a true or false activity! All resources are included.

This lesson on the gas exchange processes in fish begins with a quick review of the insect exchange system and the advantage of tracheoles being filled with water. Students are then introduced the exchange properties of fish; they should discuss as a class how fish supply respiratory gases to cells within their body tissues. They will then watch a short video and answer exam style questions based on the video. This activity should help students be prepared for a function/feature matching activity; answers are available on the following slide for self-assessment. The next task is to complete sentences explaining the process of gas exchange in fish and defining the features and functions of fish. Answers are on the following slide for self-assessment! Students are then introduced to the counter-current exchange. They should take thorough notes and understand the importance of the process. A video link is available in the notes in order to help consolidate. A worksheet with the appropriate diagrams is included. The following slide reiterates the difference between parallel and counter current flow. Points to note for an exam question are in the notes below, students will have the opportunity to answer exam style questions in the next task and answers are available for self-assessment. This lesson features a lab task for students to dissect and observe gas exchange surfaces in a bony fish. The method is set out on the slides. The lesson ends with a plenary, students should complete an exit card sharing 3 things they’ve learnt, 5 key words, and 1 question to test their peers. All resources are included.

This lesson on the human gas exchange system begins with a review of gas exchange in plant leaves and insects, and the adaptations each have made in order to reduce water loss. The first task is to fill in the blanks in a paragraph describing gas exchange in mammals, particularly humans. Answers are on the following slide for self-assessment. Students are then introduced, slide by slide, to the features of human’s gas exchange system including the nasal cavity, trachea, bronchus, bronchioles and alveoli. Each slide has a diagram, description of the feature, and explanation of its role in gas exchange. The next task is to list the features of the efficient gas-exchange system in humans, at the epithelium of the alveoli. The adaptations of the alveoli are then expanded upon over the next few slides. Students will use the included worksheet to describe the on the ways which surface area, a permeable barrier, a thin barrier and maintenance of diffusion gradient make for efficient gas exchange. The plenary for this lesson is an anagram challenge! Students can uptake an extra challenge and define each unscrambled word as well. All resources are included.
