A powerpoint that shows how to calculate %Composition and sets it in the context of fertilisers

Thanks to google earth for the satellite images. This shows the area round Vesuvius and allows pupils to discuss why some people live in the shadow of volcanoes.

A powerpoint that shows the triester structure of fats and then looks at the different types of fatty acids. Comments welcome

A simple powerpoint with a clear visual representation of how diffusion works. Higher level. Comments welcome.

A practical worksheet on the whiteboard to save with photocopying. A simple prac, put rocks in water, dry off and see if they have gained mass. A sample set of results are included. Comments welcome

Four clear powerpoint slides that show crystallinity in HDPE, random chains in LDPE, thermosetting polymers and thermosoftening polymers. I go through it using the IWB but print out the slides, two on a paged,backed, without the diagrams, to give pupils the opportunity to draw out the different structures.

This is really simple. A named monomer followed by the named polymer. The structure of both are shown clearly to help with relating the polymer to the monomer and vice versa.

A quick revision of isomerism then an animation of polarimetry. Comments welcome. This replaces a similar resource that didn't actually upload the resource!

Resource that allows students to compare the spectra of the isomers of butanol and identify the unknown

Help your students to turn the name of a chemical into the chemical formula. A carefully constructed sequence of exercises will teach your students how to write chemical formulae. Starting with simple binary compounds and working up through complex ions, like sulphate and nitrate, until they get to brackets. Then students are taken through writing equations with a worked example and then a series of questions. If you like this, leave a review, some constructive criticism or some questions.

A power point to show the alkane family properties both chemical and physical.

A power point that explains double bond structure. It starts wityh bond angles and develops into sigma and pi bonds. Comments welcome.

I don't know what prompted it but a student asked me, 'How many atoms are there in me?' After a quick calculation based on her mass and the atoms all being carbon, the number was too big to visualise. Hence the subsequent question from the same student, 'So how big would that be if every atom was a one pence piece?' This is the result. Thanks Niamh, for the original question

This introduces cis and trans isomerism. Let me rephrase that. This introduces E/Z isomerism.

This powerpoint is meant to be used in conjunction with a molecular modelling kit. Students work in groups to build what they think are the isomers called for. They can then rotate the chains to find out which ones are the same. Namenclature can also be tested Comments welcome.

A version of the glossary provided by the exam boards. This one has had its reading age reduced but not it's content or it&'s usefulness. It can also be used to introduce the terms in KS3 if you are 'Getting Practical'

This can be used as an introduction to ethene. It is designed to help students link the displayed formula, that is common in texts, to the idea of a covalent bond being a shared pair of electrons. Comments and feedback are welcome

A powerpoint that can be used as an alternative to a worksheet for the reaction of zinc and sulphuric acid. Using a little copper sulphate solution will speed it up

A powerpoint to display with all the relevent details and a worksheet if needed

A powerpoint instruction sheet and an excel spreadsheet that plots the graphs for you
