Once this task is complete students can self-assess their work using the mark scheme provided. Next, students are introduced to some of the basic concepts of naming compounds. Students are shown a particle diagram of a carbon monoxide molecule and a carbon dioxide molecule and are asked to ‘Think > Pair > Share’ their ideas about which is which. The answer is then revealed and students are shown that molecules with an atom of one element alongside an oxygen atom are called ‘oxides’, those with one oxygen atom are called monoxides and those with two oxygen atoms are dioxides. Students are now given a table with some information missing out of it, students will need to identify either the name of a compound or the elements that are found within a named compound. Once complete, the task can self-assessed using the mark scheme provided in the PowerPoint presentation. The next part of the lesson focuses on chemical formulae, students are shown what the chemical formula of a substance tells us about that compound, in terms of the relative number of atoms of each element found in that compound. Students will then need to complete a worksheet to assess their knowledge of what they have learned so far this lesson, first part requires students to name the elements found in a set of compounds given the name or the chemical formula. Second task requires students to identify the number of atoms of each elements in a set of compounds.

For more lessons designed to meet specification points for the NEW AQA Trilogy specifications for Biology, Chemistry and Physics please see my shop: https://www.tes.com/teaching-resources/shop/SWiftScience This lesson begins with a recap of normal body temperature and what happens if the temperature falls above or below this temperature. Pupils will also be introduced to the role of the thermoregulatory centre and thermoregulatory receptors in monitoring body temperature. Pupils are then asked to discuss and produce a list of mechanisms that helps the body to cool down on a hot day. This leads onto describe the role of sweating and vasodilation in cooling the body down. Pupils are then asked to consider what they think might happen if the body becomes too cold and again produce a list of mechanisms which might help warm it up. Using the PowerPoint slides the mechanisms of shivering and vasoconstriction will be demonstrated to pupils. Using this information pupils will need to copy and complete a flow diagram to demonstrate the role of thermoregulatory centre in controlling body temperature, this can be self-assessed once it has been completed. Pupils will now copy and label a diagram of the skin to show the position of sweat glands, hair, hair muscle and blood vessels, this can be marked once it has been completed. The next activity is for pupils to sort statements into two columns - one describing what happens when the body is too hot and one for when the body is too cold. Once completed the mark scheme can be used by pupils to self or peer-assess their work. The final activity is a 6-mark exam-style question on this topic, pupils should try and complete this in silence and at the back of their books to really test their knowledge of this topic. Once complete the mark scheme can be used for pupils to mark their own work. The plenary task is for pupils to pick a summary question of their choice from the two provided.

This lesson is designed for the NEW AQA AS-level Biology course, particularly the ‘Biological Molecules’ module. For more lessons designed to meet specification points for the NEW AQA A-level Biology course please visit my shop: https://www.tes.com/teaching-resources/shop/SWiftScience A-Level lesson format: I teach in more of a lecture style compared to GCSE. 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 begins with a starter to encourage discussion about the differences between the induced fit and lock and key models of enzyme action. Students are also asked to explain how temperature and pH balance affect enzyme action. The following slide briefly reviews enzyme-controlled reactions then asks students to use their mini whiteboards to write down four factors that might affect successful collision. Students can self-assess with the answers on the slide. Students are then taught to measure enzyme-catalysed reactions; in the notes I encourage you to ask students for examples and what the measurable changes are. Students can then use the slide to work through the ‘fill in the blank style’ paragraph using a graph as a guide to understand enzyme-catalysed reaction. On the board where everyone can see you should write - substrate - product (H202 -> h2 + 02). The following slide includes answers so students may self-assess or check their answers with a partner. The slides then work through a few more graphs to explain the effects of temperature and pH on enzyme action. The slides are lecture style, but you can see in my mores a few suggestions for discussion questions and further lecture material. Following these slides students are encouraged to graph on their own or perhaps as a large group. Students are then given the opportunity to answer two graph style questions in their books and then self-assess. Next the class will watch a video about measuring the rate of reaction at fixed points of time. After the video, students should answer four questions in their books and discuss the answers as a class. The next few slides build upon these questions and students are asked to practise calculating reaction rates on their own before self-assessing. The plenary requires students to solve seven anagrams in their books, then write an original sentence with each word. Each task or graph from the full lesson can be found on slides 22-27. All resources are included. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)

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.

This resource is designed to meet specification points in the new AQA Trilogy Biology ‘Cells’ SoW. For more resources designed to meet specification points for the new AQA Trilogy Biology, Chemistry and Physics specifications please visit my shop: https://www.tes.com/teaching-resources/shop/SWiftScience This lesson begins with pupils shown a picture of an amoeba and one of a polar bear, they will need to discuss the difference between the organisms in terms of how they take in oxygen from their environment. Once you have shared a few ideas from the pupils with the class you can show the pupils the difference between the two organisms - amoeba can rely on simple diffusion whereas larger multicellular organisms need specialised exchange surfaces. Pupils are then shown three examples of exchange surfaces - alveoli, small intestine and leaves of plants - they will need to think about how these structures might be adapted to exchange materials efficiently. You could have a short class discussion to develop these ideas. Once you have again discussed these factors with the class you can reveal the next slide which outlines the 4 main features of an efficient gas exchange surface. Pupils will then be given a worksheet and they will need to move around the room reading posters of information about villi and alveoli to complete the worksheet. This should take approximately 20 minutes, once finished pupils can peer-assess their work using the answers provided with the PowerPoint presentation. The plenary is an Exit Card pupils will complete and pass to you on the way out of the door, this requires pupils to write down 3 key words, one fact and a question to test their peers knowledge of what they have learnt about in the lesson today.

This resource includes PowerPoint presentations for two lessons and it covers all of the specification points for the NEW AQA Infection and Response unit. The first lesson identifies the difference between health and wellness. Pupils will then be introduced to the idea of communicable and non-communicable diseases, they will then determine whether different diseases are either communicable or non-communicable and consider the similarities/differences of the disease within each category. The last activity of the lesson is to produce a mind map of risk factors which could increase the chance of a non-communicable disease. The second lesson will start with recapping on the risk factors which can increase the likelihood of non-communicable diseases and students will need to think about whether specific risk-factors relate to specific diseases. We will also analyse the most preventable threats to health globally. Pupils then answer then ‘Think, Pair’ Share’ on why governments might run ‘keep healthy’ campaigns, what benefit might that be to the government and to it’s citizens. Pupils discuss and then answer questions on this topic. Plenary - recapping on the key words related to these two lessons.

For more lessons designed to meet specification points for the NEW AQA Trilogy Biology, Chemistry and Physics specifications please visit my shop: https://www.tes.com/teaching-resources/shop/SWiftScience The lesson begins by completing an activity which recaps the role of each of the components of blood. Pupils are then introduced to the three types of blood vessels - artery, vein and capillary. Looking at a diagram provided pupils will need to consider the differences between the three in terms of structure an function. Pupils will then watch a video and answer questions about arteries and capillaries, the answers to the video are provided so that pupils can then self-assess their work. The next slide will show how veins are structured and how they work to move blood back to heart from the rest of the body. Pupils could draw a diagram to represent this if there was time. The next part of the lesson is the longest activity, pupils will need to either copy the blank table into their books or be given a printout of the table. Using cards of information pupils will need to complete the table, which shows the structural features of each of the blood vessels. The answers to this activity are provided so that pupils can either peer or self-assess their work. The next activity is a quick fill-in-the-blank task to demonstrate the role of the capillaries within the body. Students are now introduced to the idea of a double-circulatory system, using a diagram and a description of the system pupils will need to answer questions about the role of this system, which can then be self-assessed. The plenary task is for pupils to pick one question to answer from a list of traffic-light questions, green for most difficult and red for easiest.
