This lesson starts with a review of resting and action potential and then progresses into how the impulse moves along the axon using saltatory conduction. Later, factors affecting speed of transmission is covered using diagrams and videos. All resources included.

This lesson starts with recall of how resting potential is maintained and the functions of the sodium potassium pump and voltage gated channels. The lesson then progresses into the the generation of an AP and the all or nothing response. Repolarisation and hyperpolarisation is covered. PPT is visual and includes videos to embed concepts. All resources are included in the PPT.

This lesson revisits the role of chemoreceptors in the tongue and then progresses into how resting potential is maintained until a stimulus reaches threshold. The lesson introduces the membrane sodium potassium pump using active transport and the voltage gated channels using facilitated diffusion. There are videos included and a short quiz as a plenary.

This lesson starts by recalling the role of receptor cells and then looks at the structure of chemoreceptors on the tongue. The lesson progresses into how an action potential is generated following salt detection. A lot of visuals to embed understanding.

This lesson starts be recalling differences between hormonal and nervous control then revisits KS4 learning on the neurone and the CNS. Sensory, relay and motor neurones are covered, including the finer ultrastructures. All resources included.

These two PPT’s cover all glands and the hormones they produce. They can be used for all exam boards and their specifications. Both PPT’s contain many visuals and cover the consequences of the deficiency of certain hormones on the body. The PPT’s also cover the differences between exocrine and endocrine glands, including the 2nd messenger model for for cell signalling.

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 builds on protein structure and uses haemoglobin and collagen as examples of globular and fibrous proteins. Opportunities for students to research for themselves, followed up with structured notes and a summary exercise to compare similarities and differences between the two types. Also included are the Biofactsheet notes.

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 builds on previous learning of the isomers of glucose. The lesson starts with a quiz to review and then progresses into the different types of polysaccharides: Storage and Structural. The lesson provides visuals of their structures, types of bonding and explains how their structures allow them to complete their functions. The lesson concludes with a recall quiz. Also included is an assessment on the whole topic of carbs and a Biofact sheet on the topic.

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 provides guidance for AS students to complete all food testing including extra help with the non-reducing sugar test. Consolidation exam questions are also included.

This lesson reviews KS4 learning on limiting factors then progresses into the higher level concepts using their learning on the LDR and ILR.

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 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 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.

A sort lesson outlining two methods for testing blood sugar concentrations: Urine dipsticks and blood biosensors.

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.
