A Drag & Drop exercise for building up the electronic structure of atoms. After a short cartoon for building up an atom of calcium, students build up four atoms by drag and drop. Could be used projected on the whiteboard or by students individually at computers. Double click on the full atomic structure.html file and it will open in your browser. I made it big for projection, but it can be made smaller by zooming out using the browser zoom control.

This is a variation of my ‘drag and drop functional group’ activity. In this case you drag the structural formula to the correct name of the functional group. If it is correct it will stick, otherwise it won’t. Could be used around the whiteboard as a quick AFL. This is a simple html5 document- simply double click on the html file and it will load in your web browser. (nb because the table is long, you may have to zoom out in your web browser to complete.) ** Please note:** in order to provide a rich interactive experience, my interactive resources are mini-web sites local to your computer.

There are erroneous diagrams on this web site for this diagram. I aim to correct this . Keynote, powerpoint and pdf formats.

For fun

Distance/time and velocity/time labelling excercise. With answer sheet which could be used as a handout for notes.

Preparing for a lesson with a student on waves, I was searching for diagrams to illustrate it. The internet is awash with suitable diagrams, but they all seem to be low-resolution bitmaps. Being a vector graphic fanatic, I made some high quality graphics of my own. I offer them in pdf, keynote and powerpoint formats. If you would like the editable svg files, get in touch with me via my web site

I made a very simple information sheet/poster. PDF so can be printed at any size.

I illustrated the canonical molecular shapes in this very simple presentation. For fun really.

A simple simulation of the experiment. Unzip the file. Open the folder. Double click on ‘spring stretch version 4.html’ and it opens in your browser. Add the masses by clicking the buttons, and watch the spring stretch. Use a ruler to measure the extension. (The anomaly on the graph at 3N is probably due to a draught of warm air expanding the spring as a door was opened). Enjoy! A preview is availableon my web site.

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 on my web site.
