I taught chemistry for 25 years. I now provide tuition online. I just like nicely produced, imaginative resources. (NB &1.00 is the lowest price that I can charge for my resources, that have an unlimited license. For each £1.00 sale I receive £0.35)

A little bit of ‘learning without working’ activity for the end of term, in black and white for easy cheap photocopying. Suitable for all abilities, but earlier years may need to look some clues up. The answers are included.

I made a very simple ‘fill in the gaps’ worksheet. It may be useful because it focuses on the adjectival and noun words in this topic.

Rate of reaction with a gas syringe simulation.

Rate of reaction with a gas syringe simulation.

(0)
I have made a simulation of the marble chips and acid experiment at four different concentrations of acid. Just double click on the “gas syringe.html” file and it will open in your web browser. You could use browser zoom controls to make it huge if you wish. Maybe take measurements of volume of gas evolved against time or just use to introduce the experiment or revise. ( the price for this could save your department many times in broken gas syringes.) Please note: in order to provide a rich interactive experience, my resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.
Neutralisation Reactions

Neutralisation Reactions

(0)
This is a simple worksheet about writing word equations for neutralisation reactions. It covers 2 pages. There are plenty of examples, which get harder as you go on. There is an accompanying powerpoint, as an additional download… NB I am well aware that exam boards, RSC and text books regard acid plus metal to be a redox reaction, which of course it is. However, in such a reaction, the pH increases to neutral and the acid has gone, so I think it can properly be regarded as neutralization of an acid. And since this worksheet is really about naming salts, I had to include it.

Drag & Drop particles: Pure element, compound, or mixtures of these.

(0)
Double click the particles.html file, and the interactive drag and drop activity will open in your web browser. Drag the picture to the best description, if correct it will stick. Distinguish between pure elements, pure compound and mixtures of both. Good AFL around the board to check understanding of particles. maybe print out solution for revision. Please note: in order to provide a rich interactive experience, my drag & drop resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.
