Simple, black and white.

A very little crossword puzzle about making salts

I have improved my video of this reaction mechanism.

A presentation to augment my displacement reactions and the reactivity series worksheet, with answers to problems.

Useful as a starter round the board. Drag the models next to the correct name. If it is correct it will stick, if not it won't. This tests understanding of functional groups and different types of molecular model. Double click on the FuncDragAndDrop.html file, and you're there

Animate your lessons. Simple, hopefully clear animation of catalytic hydrogenation of ethene.

In colour. Helps students interpret proton NMR spectra

A simple worksheet in black and white for ready photocopying. Two sides, with a summary on the front and some questions on the back.

Reinforces understanding of this important mechanism. Sixth formers LOVE to cut & stick.

This is a simple powerpoint giving names and formulae of ions. Knowledge of these can provide a key to understanding chemistry at GCSE and A level. Print these off, laminate them, and display in a prominent position in a lab. (NB I have corrected the ammonium ion error)

A simple animation to jazz up ionic bonding a little: covers sodium fluoride, magnesium fluoride and lithium oxide. Short and sweet. Just double click on ionic bonding.html and it will run in your web browser. If it’s too small, just zoom in with browser controls. A preview can be seen at on my web site.

There is an interactive version of this for free on my web site.

Double click on pretty poly(mers).html, and the activity will open in you browser. Simply drag the structure of each monomer to the box next to the name of the polymer. Good AFL around the whiteboard. A paper version is also available. Suitable for GCSE and A level students.

I made a crazy cartoon illustrating the calculation of the enthalpy change from bond enthalpies for the reaction between chlorine and hydrogen. Just for fun really. Note: the youtube version is free.

A minute video giving defintions of nucleophile and electrophile. Because I could.

I made a tiny video to illustrate this.

i made a tiny cartoon trying to explain how the halogen carrier works in friedel crafts (PS: you can use the youtube version for free)

I made an intertactive widget thingy with multiple choice questions about KS 4 chemistry. Point at the correct answer and click. Instant feedback provided. 20 fun questions.

I have made a cartoon of dot cross type diagrams for all of the structures on the AQA specification. Simple double click on the covalent bonding.html file and it runs in your browser. Its nice and colourful, big and bold (zoom in with your browser to make it as big as possible). Could use around the whiteboard, or for independent study at a computer. It’s not intended as a whole lesson, but as a useful resource that can be revisited a number of times with a class to reinforce what they need to know for the exam. Could be starter or plenary or interlude. Please note: in order to provide a rich interactive experience, my drag & drop resources are mini-web sites local to your computer.
