iGCSE Science: Reliability, Accuracy, and Validity Lesson Pack- Evaluating Experimental Data Lesson pack designed to help students understand the difference between reliability, accuracy and validity when evaluating experimental data. Created for iGCSE, but can be easily adapted to suit other exam boards. Lesson consists of… Differentiated learning objectives. RAG starter questions with extension activity, key word handouts, and answers. Accurate vs. reliable dartboard activity with worksheets. BIG PHARMA Bingo activity, with bingo statements and 15 bingo cards. “Would I lie to you?” plenary. Works really well for Year 9, 10 or 11.

Presentation covering the following information… LO1) Describe the physical and chemical (non-specific) defences against pathogens in animals, including the skin, blood clotting, wound repair, inflammation, expulsive reflexes and mucous membranes. LO2) Describe the structure and mode of action of phagocytes in the non-specific (innate) immune response, including neutrophils and antigen-presenting cells and the roles of cytokines, opsonins, phagosomes and lysosomes. LO3) Describe the structure, different roles and modes of action of T lymphocytes in the specific (adaptive) immune response, including clonal selection and clonal expansion, T helper cells, T killer cells, T regulatory cells and memory cells. LO4) Describe the structure, different roles and modes of action of B lymphocytes in the specific (adaptive) immune response, including plasma cells and memory cells. LO5) Explain the significance of cell signaling, with reference to interleukins. To accompany my “AS Immune System” Student Revision Booklet Pack (see other resources).

Full lesson on voluntary vs involuntary reactions, 3 different types of neurones (sensory, relay and motor), and reflex arcs.

Revision pack for students to fill out (including exam tips and practice questions), covering the following topics on the immune system… LO1) Describe the physical and chemical (non-specific) defences against pathogens in animals, including the skin, blood clotting, wound repair, inflammation, expulsive reflexes and mucous membranes. LO2) Describe the structure and mode of action of phagocytes in the non-specific (innate) immune response, including neutrophils and antigen-presenting cells and the roles of cytokines, opsonins, phagosomes and lysosomes. LO3) Describe the structure, different roles and modes of action of T lymphocytes in the specific (adaptive) immune response, including clonal selection and clonal expansion, T helper cells, T killer cells, T regulatory cells and memory cells. LO4) Describe the structure, different roles and modes of action of B lymphocytes in the specific (adaptive) immune response, including plasma cells and memory cells. LO5) Explain the significance of cell signaling, with reference to interleukins. LO6) Examine and draw cells observed in blood smears. LO7) Describe the structure and functions of antibodies. LO8) Describe the actions of agglutinins and anti-toxins. LO9) Describe the difference between primary and secondary immune responses, including the roles of T memory and B memory cells. LO10) Describe the differences between active and passive immunity, and between natural and artificial immunity, and state examples of each. LO11) Describe what autoimmunity is, and give examples. LO12) Explain the main principles of vaccination and the role of vaccination programmes in the prevention of epidemics.

Full lesson with differentiated starter, challenge questions, quick check true or false questions, and 3-2-1 pyramid plenary.

Whole lesson PowerPoint containing… BRONZE/SILVER/GOLD differentiated starter questions Learning objectives Numeracy activity labeling the structure of the gas exchange system How we inhale/exhale Links to aerobic respiration How the lungs are adapted to gas exchange Composition of the air we inhale and exhale How lung volume is measured QUICK CHECK true or false questions What have I learnt today plenary.

Full Year 8 science (biology) lesson on aerobic respiration, containing… Starter activity: bronze, silver and gold level (plus extra challenge). What is aerobic respiration? How are the reactants/products of respiration transported around the body? Quick check: TRUE or FALSE questions. Why do we need energy? Comparison of aerobic respiration to breathing, combustion, and anaerobic respiration. Quick check: Word Match activity.

Full Year 12 (AS) lesson on the roles of lipids, with starter activity (true or false), main activity (summarise the provided article), and multiple choice questions to finish.

KS3 Food Detective (Food Tests) Bingo Lesson Starter Activity Contains class instructions, calling card statements, and 15x bingo cards. Perfect for a class of approx. 30 students to work in groups of 2 or 3. Great for recapping/revising the tests for proteins (Biuret solution), fats (ethanol solution), sugars (Benedict’s solution), and starch (Iodine solution).

PowerPoint Presentation containing printable “fill the gap” revision cards (plus answers) for AS/A Level Year 12/13 (OCR) Biology (Biological Molecules) Carbohydrate Lessons. Cards include: Monosaccharides - alpha-glucose, beta-glucose, and ribose. Disaccharides - maltose, sucrose, and lactose. Polysaccharides - amylose/amylopectin (starch), glycogen, and cellulose (how their structure is related to their function). Glycosidic bonds, condensation reactions, and hydrolysis reactions. All cards are colour-coded, numbered, and link to each other.
