This first lesson starts with a recall from KS4 of the outline of the structures and roles of phloem and xylem. The lesson then progresses on to describe their distribution in roots, stems and leaves. The second lesson progresses onto identification of the vascular bundles on micrographs, to look at the structures of the xylem and phloem in detail and describe their internal structures to their function. The lesson concludes with an overview of the role of companion cells.

This lesson starts with a review the meaning of the term ‘species’ and then students learn of the three domains: Archaea, Bacteria and Eukarya. The lesson progresses to look at the characteristics of the four Eukarya Kingdoms, finishing off with an outline how viruses are classified.

This lesson covers the differences between structural and regulatory genes, and repressible and inducible enzymes. It progresses to cover genetic control protein production in prokaryotes using the lac operon , and the to describe and explain the use of transcription factors in plants.

This lesson guides students into how to conduct this practical by measuring the product formed and the reactant used up. Illustrations and instructions are provided in the PPT.

This lesson starts with a recall KS4 chromosome structure. The lesson then progresses into the structure and functions of: DNA; Histones; Chromatids; Centromeres, and Telomeres.

This lesson outlines the main stages of cell signaling that can lead to: Secretion of ligands from cells; Transport of ligands to target cells, and binding of ligands to cell surface receptors on target cells.

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.

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 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.

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.
