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.

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 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 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 covers all stages of respiration with an interactive PPT and other resources to support stuents. The lesson starts with a review of mitochondria structure, ATP role and structure and the introduction of the different types of phosphorylation. The lesson then progress through the four stages of respiration including a running total of ATP used/produced at each stage. Also supplied are Biofact sheets and CIE exam questions.

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 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 starts with past iGCSE exam questions on homeostatic mechanisms for temperature control, blood glucose control and water control. The lesson then progresses to look at the importance of homeostasis in maintaining dynamic equilibrium. Feedback loops introduce the idea of negative feedback. There is a small section on positive feedback, which although is not on the CIE syllabus, is useful for students to understand the concept of the importance of negative feedback switching off. All resources are included at the end of the PPT, and the starter activity is provided as a separate document. Also included is the Biofact sheet for this subject.

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 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.

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

This lesson starts with a review of different glands, their hormones and roles that they have in cell communication. The first learning episode looks at the principles of cell signaling and then uses insulin as a worked example. There is a practise exam question included and resources for the starter activity.

This lesson starts with a practical activity to recall the iodine food test and then discover the effect of different temperatures of amylase. Students write up their results and conclude with graph interpretation, using key terms. The lesson progresses into the effects of pH, with a YouTube video to embed the effects of temperature and then introduces the concepts of changing concentrations of H+ and OH- ions. The lesson then concludes with a past exam question. Also included is a CIE assessment with mark scheme.

This lesson starts by revisiting the location of the endocrine glands and then focuses on the pancreas and recalling it’s role. The PPT takes students through the release of insulin and glucagon from the liver, and the breakdown of glycogen in the liver. A quiz and review activity before introducing the concept of negative feedback. The plenary reviews the treatments of types 1 and 2 diabetes. Also included is a CIE specific assessment with mark scheme.

This lesson starts by comparing the nervous and endocrine systems. The students are then given a body outline of the endocrine system for which they need to research to identify each gland. The progress into researching the roles of each gland. The lesson concludes with a multiple choice quiz. Also supplied is a CIE specific assessment with mark scheme.

This lesson outlines the reflex arc in detail. The starts with a revisit to the three main types of neurones and students are then asked to investigate reflex actions, using torches (eye), and rulers on the knee and ankles. This leads to a discussion about how reflex actions are fast responses to stimuli and how this leads to survival in terms of evolution. The PPT shows the stages of the reflex arc and in the resources section there are alternative / additional activities that can be used depending on the learning styles of the class. For example, there are word cards that can be printed and students are given a word and they have to arrange themselves in the correct order of the reflex arc. There is also a cut and stick activity, if required. The lesson concludes with a revisit to the stages and students need to outline the stages of the reflex in the leg.
