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.
NMR examples explained

NMR examples explained

13 Resources
Colourful, comprehensible, clear examples to illustrate the interpretation of proton NMR spectra. Could be used as a display, or on the whiteboard, or as a handout.
The pH scale

The pH scale

(0)
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.
Chemical Formulae

Chemical Formulae

(0)
A simple, photocopiable worksheet (black and white!) that gives practice at interpreting simple chemical formulae. The examples get harder as you proceed. It is comprised of two pages of examples. It is suitable for KS3 and KS4 students. It could be used in class or for homework.
Phenol worksheet

A simple, readily photocopied worksheet on phenol. Information on the front, six questions on the back.

Naming organic substances 1

A simple worksheet on IUPAC nomenclature. A set of simple rules, followed by nine questions (branched chain alkanes and alkenes) over two sides. With separate answers sheet. First of a series.
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.
Esters worksheet

Esters worksheet

(0)
Introduction on the front, eleven questions on naming esters on the back. All in black and white for photocopying cheaply. To save you some time. Useful for GCSE, but could be used at A level.
Ions

Ions

(0)
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.
Relative molecular mass.

A simple worksheet giving lots of examples of calculating Mr values. answers included. Black and white for ease of photocopying. Consists of introductory page, examples on back, and final page with answers.
Electronic configuration and the Periodic Table Interactive

Electronic configuration and the Periodic Table Interactive

(0)
This is an HTML version of my Electronic configuration and the Periodic Table activity. Double click on the periodic table.html file et voila… . drag the electronic configurations to the correct elements. This provides an excellent understanding of the layout of the periodic table and its basis in electronic structure. Can be used many times, say as AFL on the whiteboard. (pleas note: I made it big for projection, but if it’s too big or small, simply zoom in or out with the browser zoom control.) 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.
