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 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 from the previous one on kidney structure. The starter revisits kidney structure and moves onto the nephron structure. There are YouTube videos and lots of visuals to help students understand concepts. Finally the lesson looks at the importance of the Bowman’s capsule, glomerulus and the proximal convoluted tubule in ultrafiltration and selective reabsorption. Additional supporting starter sheets and writing prompts included.

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 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 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 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.

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 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.

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 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 geotropism and phototropism, the role of auxin and it’s effects on plant growth. There is a link to the practical to investigate both tropisms. The lesson concludes with a short assessement using CIE specific questions - included with mark scheme.

This lesson starts with a review of the definition of homeostasis and recall of the role of the kidney. The main body of the lesson explores the three roles of the skin, including it’s role in temperature regulation. Students are given a diagram of the skin and are asked to label it, extension questions within the PPT slide are there to prompt ideas about how the involuntary nervous system controls the sweat glands and hairs. The lesson looks at physiological responses to temperature and the role of the thermoregulatory centre in the brain. Finishing off with higher tier components of vasodilation and vasoconstriction. The plenary concludes with a multiple choice quiz. A CIE specific assessment and marks scheme is also included.
