First lesson for CIE iGCSE Biology on characteristics and classification of living organisms. The PPT gives examples of each of the seven characteristics along with a task sheet to give examples of the characteristics in both plants and animals. A summary crossword task for the plenary.

The lesson starts with identifying and describing the terms ‘ecosystem’ and ‘niche’ and then how the different levels that biodiversity can be assessed at. The lesson concludes with an explanation of the importance of random sampling, suitable random sampling methods and use the Lincoln Index. Full worked examples included.

This lesson starts with a review of different classes of drugs and thenwhat antibiotics are used for. The lesson then explains how they work with an analysis of how antibiotic resistance can occur and how we can stop the spread of antibiotic resistance. Fully resources with videos and exam questions.

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 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 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 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 with a recall of the names of some specialised cells taught at KS3. The lesson then progresses into a research activity where they are given a visual worksheet with the cells already drawn. Students need to research the individual adaptations of each cells and then explain how their adaptation allow them to do their function. Resources are included in the PPT. An additional assessment sheet is provided which students can be given as a homework task.

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 provides opportunity for students to discover the main features of ferns and flowering plants (dicotyledons and monocotyledons) of the plant kingdom. Students start the lesson with a recall classification exam questions and review the 5 kingdoms. The main body of the lesson is for students to research the four main plant groups and then delve deeper in the specific characteristics of ferns and flowering plants. Students then identify differences between monocotyledons and dicotyledons. The lesson concludes with CIE specific exam questions. Mark scheme included. Finally there is also a CIE specific test that can be used as a summative assessment for the whole of unit one - Characteristics and Classification of Living Organisms. Mark scheme included

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 all the learning objectives for plant homeostasis as per the CIE specification. It focuses on the structure and function of stomata, how they are able to open and close during their daily rhythm and the use of abscisic acid and calcium during times of water stress. Lots of visual diagrams outlining the stages of the process. CIE specific exam questions are also included.

This lesson starts with a recall of actin and myosin structure. Then probes further in the the roles of the regulatory proteins troponin and tropomyosin. The structure of the sarcomere is covered including identifying parts on a micrograph. Later, the process of contraction is covered as per the sliding filament theory. the cross bridge cycle is covered in details including the role of calcium, ATP and the regulatory proteins. Exam questions included.

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.
