How to calculate the empirical formula of a compound from the masses of the elements in it or the percentage composition. A written explanation, a worked example in two formats and a series of calculations to try out. Comments and feedback welcome.

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 Powerpoint animation of the electrolysis of brine. Comments welcome

Best printed out on A3. Each broadsheet contains a series of boxes that contain questions about the relevant syllabus section, C1, C2, C3. Pupils can complete these at home or in class in pairs or groups. When complete makes a sort of mind map effect. Reviews welcome.

Isotopes of hydrogen are used to show what isotopes are. Calculations of Relative Atomic Mass are covered through a worked example using chlorine and then an exercise using copper

Introduction to Mass Spec with some examples of simple fragmentation patterns. Comments and feedback welcome

starting with the mining of bauxite and finishing with an animation of electrolysis. comments welcome

Shows ozone formation and destruction in the normal stratosphere. Shows role of cfcs in destroying ozone and consequent reduction in UV absorbed Based on GCSE syllabus but includes all Y12 Green Chemistry equations. Comments welcome

Active reading sheets mean that the pupils have to read them though several times in quick succession to get the answers. They choose the titles for the paragraphs and select data for later questions. Useful tool for conveying lots of info fast and generating discussion. The sedimentary rocks sheet is just an old-fashioned cut and sort into order. Give pupils the precut sheets as they are printed in order

An active reading worksheet that contains a lot of information. Pupils read it through and then read it again to give titles to paragraphs. Then they have to read it again to sift out various bits of information. Reviews welcome

A lot of spectra, collected by functional group. Students can see, for example, the clear 3300-3000cm-1 peak for all alcohols. A useful blank table at the start, complete at the end for peer marking.

An A to Z of Science Jobs, useful as a starter or a careers talk

Active reading sheets get pupils to read the information several times and analyse it in different ways. Pupil read the sheet then re-read it to add titles to paragraphs, then re-read it to find the negatives, then re-read to find the positives, then re-read to find business strategies. A useful way to put across a lot of information without copying and with the knowledge that it will be read. Comments welcomed

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.

A very basic powerpoint and a cloze worksheet aimed at the middle to low ability. Watch the printing as the spectra are in colour and that makes the photocopying expensive. If capitation is an issue, best to print in greyscale and have students add their own colour using the presentation or use the new black and white version.

A simple walk through coupling with a few simple examples

An animated powerpoint that explains adsorption and solubilities.

A simple table of common ions that pupils can reference when working out formulae. Old fashioned but great for those stretching and challenging formulae questions

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

Triple Science Opens Doors is a powerpoint that can be used in assemblies or on interactive displays to advertise the benefits of triple science. I have also printed out the individual slides and displayed them in groups of three in labs and corridors. There are slides linked directly to food tech, product design, music, english, geography, history, so have them displayed there too!!
