A revision mat covering the Biology required practicals for the AQA Combined Science (Trilogy) specification. It includes a range of questions and activities to help students revise key methods, variables and analysis skills ahead of exams. Designed as a simple, ready-to-use resource for lessons, homework or independent revision. Supports students in recalling key information and practicing exam-style questions linked to the required practicals.

This resource is a complete GCSE Chemistry lesson on the effect of concentration on the rate of reaction, aligned with the Edexcel GCSE Chemistry specification. The lesson introduces key ideas about particles, collisions and activation energy, before applying this understanding through data interpretation and a practical investigation measuring the rate of reaction. Learning outcomes State what must happen for a chemical reaction to take place Describe what is meant by concentration Interpret tables and graphs showing concentration versus time Explain the effect of concentration on the rate of reaction Included in this resource Retrieval practice linking prior learning (rates, periodic trends, separation techniques) Clear explanation of particle collisions and activation energy Guided discussion on factors affecting the rate of reactions Practical investigation measuring gas volume over time at different concentrations Structured sections for results, conclusion and explanation Plenary task focusing on reliability, comparisons and scientific explanations Suitable for GCSE Chemistry (Edexcel) Foundation or Higher tier classes Lesson delivery, revision or cover work Ready to use with minimal preparation, this lesson supports conceptual understanding while developing practical and analytical skills required for GCSE Chemistry.

This resource is a structured GCSE Physics lesson (or masterclass) on Specific Latent Heat, designed to deepen understanding of energy changes during phase changes and develop confidence with calculations and graphs. The lesson explicitly compares specific latent heat and specific heat capacity, before applying the formula E=mL to a range of increasingly challenging exam-style problems. Pupils also analyse heating and cooling curves to identify phase changes and explain why temperature remains constant. Learning objectives Compare and contrast specific latent heat and specific heat capacity Deduce the units of specific latent heat and apply 𝐸=𝑚𝐿 Analyse heating and cooling graphs involving phase changes Included in this resource Retrieval practice on specific heat capacity and prior calculations Guided reading task to identify and explain key ideas about latent heat Clear comparison of latent heat of fusion and vaporisation Heating curve interpretation and phase change analysis Structured calculation questions with increasing demand Extended and challenge problems involving real-world contexts Mini whiteboard questions to check conceptual understanding Exam-style written questions and structured summaries Suitable for GCSE Physics (Higher tier) GCSE Combined Science (Higher) Revision lessons, intervention sessions or masterclass delivery This resource is ready to use with minimal preparation and is ideal for supporting pupils to link mathematical skills, energy concepts and exam-style explanations.

This resource is a complete GCSE Chemistry lesson on catalysts and their effect on rates of reaction, written specifically for the Edexcel GCSE Chemistry specification. The lesson builds secure understanding through a structured sequence of retrieval practice, explanation, application and practical investigation, supporting pupils in developing both scientific knowledge and required working scientifically skills. Learning outcomes Recall that enzymes are biological catalysts Explain how catalysts increase the rate of reaction Deduce which catalysts are most effective Included in this resource Retrieval questions to recap key prior learning (temperature, redox, chromatography, gas tests) Clear explanation of what catalysts are and how they work, including activation energy Diagram labeling task Video-linked comprehension questions on catalysts Practical investigation into the decomposition of hydrogen peroxide using different metal oxides Structured sections for results, conclusion and evaluation Plenary activity focusing on reliability, validity and explanations of rate of reaction
