This lesson covers how hydrogen bonding occurs between water molecules and relates the properties of water to its roles in living organisms which are limited to solvent action, high specific heat capacity and latent heat of vaporisation. Additional reources include AS level exam questions and mark scheme, and the Biofactsheet on the topic.

This lesson starts by looking at the importance of proteins in organisms. It progresses to look at the structure of amino acids and the types of bonding involved. We revisit ideas on condensation and hydrolysis reactions in polysaccharides and lipids, and then apply the same to forming and breaking peptide bonds. Student are then guided through the stages of structure from primary through to quarternary including the types of bonding involved holding all the structures together. the lesson concludes by looking at the haemoglobin molecule structure as an example of quarternary structure.

This lesson continues from the teaching on carbohydrates and starts with exam questions on polysaccharides. The lesson then progresses into an overview of lipids, their general characteristics and why are are important. There is opportunity for students to build a lipid model using molybeads as structure is taught. Recall of condensation and hydrolysis reactions is required during the teaching of the ester bond. The lesson then looks at saturated and unsaturated fats, linking this into the structure of the phospholipid bilayer. Students are given a research task to discover their importance as energy storage, waterproofing and insulation. The lesson comes complete with Biofact sheets on lipds and some additional exam questions on lipids and carbs. Mark schemes in included.

This lesson covers glycogenesis, glycogenolysis and gluconeogenesis (not required for the CIE syllabus), Colourful diagrams to illustrate sites of the Islets of Langerhans, and the concept of the second messenger model.

This lesson looks at the detail of the light dependent reaction using visual diagrams with annotations to slowly walk students through this complicated process. The lesson starts with a review on oxidation and reduction reactions to prepare students for the reactions occuring here. Consolidation activities include an activity to arrange the stages in the correct order and exam questions. All resources supplied in the lesson PPT and additional Biofact Sheet on the topic

This lesson moves on from the light dependent reaction and starts with a review of the exam question set in the previous lesson. The LDR is reviewed again and then students move onto the LIR, finishing off with a calculation of the reactant and product molecules. A consolidation cloze task and exam questions also included.

This lesson starts with a review of KS4 concepts using iGCSE past questions. The lesson then delves into discovering the components required for photosynthesis, and the three stages involved using previous A2 learning on the structure of the chloroplast. The lesson also include A2 exam questions for consolidation.

This lesson starts with a review of KS4 learning on biomolecules, then progresses onto the differences between glucose isomers and concludes with how polymers are made using condensation and hydrolysis reactions. The lesson is littered with visuals and guided instruction on how to draw alpha and beta glucose isomers. Also included with the lesson are exam questions and Biofact sheets on the topic.

This lesson concludes learning on the role of the liver in homeostasis. The lesson starts with a review of the location of the hypothalamus and pituitary gland in the brain. It then progresses into describing how ADH works to create an increase of permeability in the collecting ducts so that more water returns to the blood. The final learning episode looks at AHD and the chemical reactions at cellular level.

This lesson continues the homeostasis theme by introducing the structure and function in it’s role in osmoregulation. The lesson starts with a kidney labelling task, progressing into an outline of it’s role in eliminating urea from the blood. There is opportunity for a kidney dissection too. Also included are Biofact Sheets relating to this topic.

This lesson covers the role and structure of photosystems on the thylakoid membrane and the reaction centres within. A good lesson to teacher prior to the Light Dependent Reaction as it helps students to visualise how light is transferred through the chloroplast.

This lesson starts by revisiting previous learning on APT with exam questions on ATP reactions and the it’s role as the universal energy currency. The first learning episode is recalling the 3 macromolecules and linking their structures to how much energy they carry. Respiratory quotients is covered including how to calculate, concluding with a YouTube video on how to use a respirometer.

The lesson starts with details on why anaerobic respiration is needed and how it works in mammals and yeast. It progresses to explore why ATP yield is less, then concluding with rice and it’s adaptations to grow in anaerobic conditions.

This lesson starts with KS4 recall of plant cell organelles which then links into the structure of the chloroplast. There are a lot of magnified diagrams to illustrate structure. The lesson concludes by explaining structure to function using text from a Biofact sheet and answering questions. All resources included including additional Biofact sheets on comparisons between mitochondria and chloroplasts.

This lesson covers the absorption spectrum of chloroplast pigments and the action spectra for photosynthesis. If then takes the learners through the process of how to use chromatography to separate the pigments. A Biofact sheet is also included in the resources.

This lesson can be taught over several sessions. Students start by revisiting KS4 concepts on the role of ATP and then looking at it’s structure. The lesson then progresses to how it is made and how it releases energy, finishing off with why ATP is referred to as the universal energy currency. The PPT is interspersed with exam practise questions and mark schemes. Additional exam practise material and Biofact Sheet is also included.

This lesson starts by recalling ATP structure and Y12 learning on glucose structure. Students have opportunity to build a glucose model using moly beads. The lesson then revisits concepts of oxidation and reduction and introduces concepts of co-enzymes NAD, FAD and CoA and their role as carriers of hydrogen. The lesson concludes with 2 optional activities.

This lesson can be taught over several sessions. Students start by revisiting how to prepare slides for viewing under the miscroscope, and how to draw observations to A Level standard. YouTube videos and practical tasks are included. The PPT includes micrographs of cells for students calculate magnification and actual size. Later, students are taught how to use a graticule and stage micrograph when calibrating a microscope with practise calculations, working out sizes of specimens. The lesson concludes with a research task on the differences between light, and electron microscopes. The PPT is interspaced with exam questions to assess progress. Also included is a practical booklet that students can use to independently conduct the miscroscope practical, if required.

This lesson explores differences between prokaryotes, eukaryotes and viruses. Students start by recalling eukaryote cell structure in plants and animals and then they are introduced to additional organelles, which they research and are then presented with review slides to ensure they have all the information. Throughout the PPT there are micrographs of specimens so students are able to identify individual organelles. The lesson concludes with a multiple choice quiz.
