Biology A Salters-Nuffield Core Practical Investigate the vitamin C content of food and drink. Includes additional content, model answers and additional practice questions.

Revision of chemical reactions and conservation of mass using diagram based equations.

A series of slides that cover a range of aspects associated with graphs in science (variables, plotting, gradients, correlation and describing trends)

Biology A Salters Nuffield edexcel SNAB PAPER 3: General and Practical Applications in Biology, 2025. Scientific article ‘The Big Sleep’ Links to specification are provided within along with a small sample of possible questions that I have created. More questions and resources to follow.

The size of an atom is approximately 10,000 times that of its nucleus. Lesson revisiting Bohr model drawings, atomic particles and energy levels.

A sample of short diagnostic multiple choice questions to be interspersed into lessons throughout the teaching of the topic. Designed as a check point mini whiteboard task to check the whole class for their understanding and possible misconceptions. Organisation (Digestion system, Food tests, Cicrulatory systesm, Coronary Heart disease and Risk).

A complete lesson as per the specificaiton for AQA combined science and GCSE chemistry. This lesson follows on from balancing chemical equations. Introduces a definition for relative formula mass and associated calculations.

A complete lesson as per the specificaiton for AQA combined science and GCSE chemistry. This lesson follows on from a lesson on ‘Chemical Measurements’. Introduction to Avogadros constant, relating relative formula mass and mass to number of particles.

Lesson 1 of Energy Changes as per AQA specication (Combined science/GCSE Chemistry). Full set of slides, spaced practice and opportunity for self/peer assessment. Slides and worksheet can be easily adapted to suit other lessons/revision activities.

Infection and Response - Vaccinations Worksheet activity that elicits knowledge of how vaccines confer immunity. Scaffolded questions based on the typical graph used in exam questions to depict the change in antibody concentration before and after Vaccination / secondary exposure to infection.

Simple activity that shows conservation of mass through calculations. The use of equations with state symbols challenges students to think of situations where mass ‘appears’ to increase or decrease.

Complete lesson as per Chemical Changes in AQA GCSE chemistry and combined science. The lesson revisits metals, metallic bonding and ionic bonding. Please feel free to adapt.

AQA Combined science and GCSE Biology. 1 lesson outlinng the series of steps involved in a reflex action. Contains worked examples, worksheet and solutions.

Complete lesson and worksheets for electrolysis required practical. Can be adapted to cater for higher or foundation level. Solutions can be found on the resource (Half equations and electrolysis of aqueous solutions). Chemical Changes as per AQA combined science and GCSE chemistry.

AQA GCSE Biology lesson on decompostion as part of wider topic of ecology. Recall of cell organisation, Respiration and Photosynthesis. Introduction to core practical. Slides are easily adaptable.

A basic summary of covalent, metallic and ionic bonding with follow up questions.

This lesson allows the students to see that ALL electrophilic substitution reactions of benzene progress by the same mechanism: 1 - formation of the electrophile in situ; 2 - attack of the electrophile on the ring; 3 - reformation of the catalyst. 6.1.1 (d) The electrophilic substitution of aromatic compounds with: (i) concentrated nitric acid in the presence of concentrated sulfuric acid (ii) a halogen in the presence of a halogen carrier
