I have improved my video of this reaction mechanism.

One of the most useful skills in answering many GCSE chemistry questions is to work out what type of reaction is involved in the question. This helps you work out what the products may be, but also answer other questions about the reaction. Students often find this very difficult, mainly due to a lack of practice and experience. This simple information sheet with questions at the back is in black and white so can be readily photocopied.

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

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.

This is better than my old one.

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.

Because I could.

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.

I left it up to the students to add the arrows.

Students work out the state different substances are in at room temperature, given their melting point and boiling point.

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.
