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)

Double click on the ‘skeleton.html’ file, et voila. Drag the labels to the correct place. As AFL around the whiteboard, or individual revision at a computer. The smiley face makes it more endearing. 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.

I made a very simple labelling activity for KS3 students. (I have also produced interactive, drag & drop versions. See my 'Anatomy interactive" bundle.

The disappearing cross experiment simulation

I have made a simulation of this experiment at four different temperatures. Double click on the “disappearing cross copy.html” file and there it is in your web browser. Students time the cross disappearing, after someone presses the button and shouts go. Saves a nasty experiment with hot solutions and sulfur dioxide. Use over and over again. You can make it huge by using the browser zoom controls. A preview is available at https://www.doctorexe.com/disappearing-cross.html Please note: in order to provide a rich interactive experience, my resources are mini-web sites local to your computer.

I made a simple labelling exercise for KS3 students. It is nice and clean because it only contains vector artwork.

An alternative to my cut and stick exercise. Double click on the .html file, and it will open in your browser. You can zoom it so it’s huge using the browser zoom controls. Drag the structures to the correct places, then get a reward. Please note: in order to provide a rich interactive experience, my drag & drop resources are mini-web sites local to your computer.

I needed a clean, scalable (vector)graphic of fleming’s left hand rule that I could freely use in my resources, so resorted to drawing my own. I thought I would share it. If anyone would like to use the editable SVG version or postscript or EPS etc, contact me.

Quick and short presentation on how to balance the manganate (vii) half equation, to save you time. I have now added the oxidation of ethanol by acidified potassium dichromate (VI) as another example.
