Drag & Drop functional groups

(0)
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
Recognising the Type of Reaction

Recognising the Type of Reaction

(0)
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.

I have tried to illustrate the concept of separation of water molecules rather than breaking covalent bonds when water is heated with a quick and dirty animation. Click on the water boiling.html file and it will run in your browser.

For those year six induction days or the like, this is a drag & drop exercise to label the bunsen burner. Double click on the html file and there it is! 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.

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.
