This lesson is designed for the NEW AQA Trilogy Biology GCSE, particularly the ‘Ecology’ SoW. 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 starts with a PowerPoint slide which demonstrates how sunlight falling on plants is the initial source of energy for all living organisms. This moves on to a video which outlines the key terms related to food chains, pupils will be provided with a set of questions which they will need to answer using the video. Once pupils has completed this task pupils they can self-assess their work using the mark scheme provided. Pupils will then be shown an example of a food chain and the PowerPoint slide will reiterate what the video outlined, about what a food chain and the arrow in the food chains demonstrates. Pupils will then need to complete a task where they match key terms to their definitions and examples. This work can assessed once the task is complete. The next part of the lesson will focus on animal populations and dynamics. The first task pupils will be given a set of questions about the impact of various changes on animal populations (i.e. predator numbers, disease). In groups/pairs they will be given a piece of A3 paper and they will need to answer the questions as best they can. Pupils can then check their answers against the answers provided in the PowerPoint presentation. Pupils will then be given a food web and asked a set of questions about how various changes in the numbers of organisms within the food web would impact others, again this work can be self-assessed. The final activity is for pupils to draw a graph to represent data on the numbers of coyote and jack rabbits over the course of twenty years, pupils will then need to answer questions about this data. The plenary task is for pupils to complete a food chain choosing from a set of organisms provided on the PowerPoint slide, as an extra challenge pupils could try and complete their own food webs. All resources are included at the end of the presentation. Thanks for looking, if you have any questions please let me know in the comments section and any feedback would be appreciated :)

This lesson is designed for the NEW AQA Trilogy Biology GCSE, particularly the 'Homeostasis' SoW. 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 Pupils will start the lessons by considering why a reflex action is important to living organisms and asking pupils to consider any examples they can think of. After revealing the importance of reflex actions and come examples, the slides then move on to look at the pathway an electrical impulse takes along a reflex arc. Pupils will delve a little deeper into this by watching a video, during which they can answer questions. Once this has been completed they can self-assess their work using the answers provided. This process can also be summarised using a copy and complete exercise. Next, the lesson focuses on synapse, a diagram of a synapse is shown with key details labelled, there is also a link to an animation that can be shown to demonstrate what occurs at the gap between neurons. After this has been demonstrated pupils are then asked to complete some tasks to show their understanding of what occurs at a synapse. The next activity involved a set of statements which are muddled up, pupils need to put them into the correct order to correctly describe the steps involved with a reflex arc. Once this has been completed pupils can assess their work using the model answer provided. The final activity is a past-paper question which can be printed for pupils or they can complete in their own books, this needs to be self or peer assessed once complete. The plenary task is for pupils to pick a task - either to summarise the work from the lesson using a list of key words or for pupils to come up with questions for the list of answers that are provided.

This lesson is designed for the NEW AQA AS-level Biology course, particularly the ‘Organisms & their Environment’ 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 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.

This is a resource for the new GCSE AQA Specification, it meets specification points from the ‘Infection & Response’ unit. This resource contains two shorter lessons or one full lesson on bacterial & viral diseases. Bacterial disease: This lesson begins with pupils considering why death rates due to infectious diseases are now 30% lower than they were in the early 20th century. You will then introduce the three bacterial diseases the students will need to learn about - salmonella, gonorrhoea and bacterial diseases in plants - and ask students to discuss what they already know about these diseases. Pupils will then copy the table from the PowerPoint into their books and they can either read information in pairs or use the information placed around the room to complete the table. You could check the students have recorded all relevant information by self-assessing the work using red pens. For the mid-lesson plenary some statements about bacterial diseases will be read out and pupils can use thumbs up/thumbs down or RAG cards to show whether they think the statement is true or false. This will give you a chance to address any misconceptions. The next activity can be a silent task, pupils complete questions in their books and when finished they should peer-assess using their red pen. The plenary is an exit card (piece of paper) where pupils should write down a topic they feel secure with and an area which they do not feel as secure with. This can be addressed at the beginning of the next lesson. Viral diseases: The lessons starts with a recap on the viral diseases the students would have learnt about a beginning of the unit when covering communicable and non-communicable diseases (see my Health & Wellness lesson). Students can discuss and then a mind map can be brought together on the white board. Pupils then draw a table into their books and use the information around the room to complete the table. This is then followed by a mid-lesson progress check, pupils will answer questions in silence in their books which are then self-assessed using red pen. You can then conduct a game of key word bingo with your students. This works by pupils choosing 6 of the key words from the board and you can randomly read definitions of these key words, if pupils have they key word they should cross the word out. Once all 6 of their key words are crossed out they can call bingo! The plenary is a 3-2-1 recap of the lesson, pupils should write three facts they have learnt, two key words and a question to test their peers knowledge of viral diseases. If there is time at the end of the lesson All of the resources are found within the PowerPoint :)

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 lesson is designed for the NEW AQA Trilogy Biology GCSE, particularly the ‘Ecology’ SoW. **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 ** The lesson begins with students recapping on the factors which may affect the distribution of organisms within an environment. Once pupils have discussed their ideas of abiotic and biotic factors which may affect organisms within their habitat they will need to assess their work using the answers provided. The lesson will then focus on sampling techniques, firstly outlining what a quadrat is and how it is used when sampling an environment. The importance of random sampling is stressed & pupils will need to come up with some ideas as to how random samples could be obtained. Once their ideas have been assessed pupils can then move onto a worksheet which demonstrates how random sampling is conducted and explains how to work out the range, mean, median & mode of a data set. Transect sampling is now introduced, pupils will watch a video and answer a set of questions watching the video.
