PowerPoint on selection at AS level, Includes an introduction to the work of Florey, Chain and Heatley on the development of penicillin and links this to (earlier year 1 material about) prokaryotes. There's a card sort activity, which students match up with numbers associated with images of antibiotic resistance which is used to and illustrate directional selection. Stabilising selection is exemplified by human birth weights. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic. There's also a very quick meiosis quiz included for a recap.

PowerPoint introducing the topic. Contains a starter question and a quick video, with one of my favourite quotes, before using the manufacture of synthetic insulin as an example to illustrate where this field of DNA technology originated. it outlines the different steps involved in the topic for the isolation, replication and identification of the desired gene/protein, and then introduces stick and blunt ends. Where possible, there are links to previously taught material. The PPT contains (a few) notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

PowerPoint introducing gas exchange in fish. Brief animation to explain the countercurrent mechanisms, but it's quite a short PowerPoint (hence the price) and is really designed to be used with the class notes for this topic. The PPT contains notes with most of the answers to the questions on the PPT. Also included is a model students can make of fish gills, including lamella. The idea is they draw on the direction of the blood flow and direction of water movement across the gill filament.

Very short PowerPoint introducing gas exchange in Humans. This contains a diagram for students to identify the structures in the gas exchange system and are then posed a few questions about the gas exchange system. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic, which contains many activities associated with this lesson. Also included is a PowerPoint which can be used to test basic recall of lung structures.

Very short PowerPoint introducing the mechanisms of breathing. Also included is a card sort activity for inspitration and expiration, before moving on to consider pulmonary ventilation. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic, which contains many activities associated with this lesson.

Two PowerPoints - one on gas exchange in the lungs, and the other on data and disease, which includes an introduction to cause and correlations. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic, which contains many activities associated with this lesson.

PowerPoint introducing the concept of surface area to volume ratio in biology. Contains a few questions about what organisms exchange and why, but then includes a video about bats and surface area to volume ratio (i then ask my students a question about oxygen uptake and mass of organisms a few lessons later, and remind them of this video as a clue when they get stuck!). However, as with all my resources, this is designed to be used with the class notes for this topic, which requires students to calculate S.A.:vol ratios and plot the data on a graph, before answering a few questions. I would be cautious about purchasing this and expecting to use it to deliver a good lesson if not using the work sheet. I have however included another activity and marking guidelines for an activity on S.A.:Vol.

PowerPoint introducing gas exchange in single celled organisms and insects. Contains a few videos, firstly showing some very interesting single celled organisms (to try and help stimulate student interest), but then of the abdominal pumping movements of a locust. There are a few questions that then follow about gas exchange in insects, which includes a graph about spiracle opening. Where possible, there are links to previously taught year 1 material (i.e. drawing a labelled amino acid). The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

Very short PowerPoint introducing gas exchange in the leaf of a plant, a topic area student's generally find quite dull! This contains a diagram for students to identify the structures in the cross section of a leaf and later on, a video introducing the stomata. They are then asked a few questions about the opening and closing of the stomatal pore. Where possible, there are links to previously taught year 1 material (i.e. osmosis). The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

Topic overview check sheet for use when peer-marking student overview of this topic. I give these out and usually give my classes a week to hand write their notes (unless they have access to word processor in examinations) and complete the exam style questions from the text book.

Class notes to accompany the PowerPoints available on TES for this topic. This will save you hours and hours and hours and hours of preparation! The booklet is 54 pages long and contains gap fill paragraphs, questions, images for students to label, past exam questions and much more. Marking guidelines also included, along with a separate booklet of exam questions (and marks scheme) associated with this topic.

Lengthy PowerPoint detailing enzymes and digestion, designed to completement the bespoke class notes for this topic, available separately on TES. It starts off by labelling the major parts of the digestive system, but then students are expected to use the spec to identify the parts they actually need to learn(!). There is an activity - 'guess the parts of the digestive system' and then physical breakdown and chemical digestion are outlined. There's a quick bit of carbohydrate revision before students are tasked to arrange the cards so they detail starch digestion in mouth and illeum. The PPT then moves on to protein digestion, before the processes that lead to amino acid absorption via the co-transport mechanism are considered. There are links to previously taught year 1 material (movement across membranes). The PPT contains notes with most of the answers to the questions on the PPT, but also some answers to the activities in the class notes about lactose intolerance a table which students complete, using the information covered in the lesson - it's quite challenging for them!

Student notes / work booklet to accompany eight lessons on the topic of Cell structure. Contains several application activities and exam style questions Marking guidelines, card sort (for differences between prokaryotic and eukaryotic cells) and images of organelles are also included.

PowerPoint reviewing the basics of inheritance and introducing the topic. Where possible, there are links to year 1 material. The PPT contains notes with most of the answers to the questions on the PPT. This resource is designed to be used with the class notes for this topic.

Very short PPT on the cell cycle. To accompany the class notes for this topic.

Complete set of pre-work, PowerPoints, bespoke student class notes, any additional resources and marks schemes for nine 1.5 hour lessons covering the AS / Year 1 Biology topic of Biological molecules, including enzymes (AQA). The Student notes are available to download separately, so you can view these in their entirety. In this bundle, the class notes, PowerPoints and all other resources are fully editable to suit your style of teaching. They make reference to, and may require students to access both the Toole & Toole and AQA A Level Biology Student Book 1 (Lowrie & Smith) for some independent study. The pre-work contains links to websites, videos and some images in the folder dividers. The pre-work also requires students to complete a topic glossary (in the folder dividers), which are also available on TES, along with accompanying images. It is important students complete the pre-work prior to the lessons because they are then tested on their understanding of the pre-work throughout the topic. The topic overview sheet is for students to write up their notes after the topic has been taught. An exemplar student topic overview is included, which I tasked my students to assess prior to them completing their first topic overview. If upon purchasing these resources, you need any support, I'll do my utmost to help. These materials have been trialed & refined last year and played a central role in enabling my classes (sizes of 20+) to achieve ALPS scores of 2.

PPT for lesson on diabetes. Should be used with the handout for this topic and purchased as part of the bundle. Also includes a starter exam question on synapse inhibition.

Activity about xerophytes and their adaptations. Students are tasked to produce a two sided A4 fact sheet using the T&T text book. Students then peer assess it using the marking grid. Also included is a practical instruction sheet investigating the effect of interrupting a part of the vascular system on the movement of dyes in a celery leaf and a leaf of spider plant.
