I am a TES recommended author and a UK Science teacher with a Chemistry specialism.
You'll find various KS3 and KS4 Science resources here (Biology, Physics and Chemistry) as well as some A level Chemistry stuff. I try to make my lessons visually appealing, with clear diagrams and text and a variety of different tasks.
If you have any suggestions of resources you'd like to see uploaded, I'd be happy to hear from you.

A year 12 (AS level) guide to solving Hess cycle questions on enthalpy change of reaction, using either enthalpy change of combustion or enthalpy change of formation values. Includes detailed instructions and one worked problem. Could also be used for year 13 (A level).
A year 12 (AS level) resource for solving bond enthalpy questions. Could also be used for GCSE or year 13 (A level).
This contains a numbered guide of how to solve these types of questions and includes 2 worked examples, following the guide.
Shapes of ions and molecules lesson for year 12 or year 13 (AS level or A level).
LOs:
To state the basic features of a molecule that determine its shape.
To describe different molecular structures.
To predict the shapes of simple molecules and ions with up to six electron pairs surrounding the central atom.
1. Do Now: Draw the Lewis structures for water, methane and ammonia. How many pairs of electrons surround the central atom in each case?
