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)

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

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.

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.

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

This lesson looks at how scientific knowledge develops over time as more evidence becomes available. It is also a chance to review the shapes of atomic orbitals as it builds on knowledge of side-on overlap of the p-orbitals to form the delocalised pi ring of electrons. Students meet the arenes in year 12, but only in passing, so they will have little idea as to the molecular and structural formula of benzene.

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.

An introduction lesson to electroylsis based on chemical changes for AQA combined science and GCSE chemistry. Recap of ionic bonding and state symbols. Predictions electroylsis of molten salts. Simple half equation examples.

Interactive set of slides that focus on revision of some practical skills and retrieval knowledge from OCR A / OCR B Chemistry at AS level. Feel free to include some / all slides as part of a revision lesson.

Demonstration of how to interpret command words and how to show your thought process when responding to extended writing Q. These slides offer some examples and can be used as a basis to build a greater bank of model answers / model approaches.

Additional resources to support students preparation for Biology A (Salters Nuffield) Advanced PAPER 3: General and Practical Applications in Biology. Please feel free to use resoures as part of your own teaching.

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.
