I made a simple worksheet about density. 5 pages. Two of info, one table of values, a page of questions and my answers. I have now added a keynote and powerpoint version.

simple labelling exercise

Made for my own satisfaction I have now added a set of bingo cards as an alternative

I made a little presentation about working out the number of each atom from the formula. As keynote, powerpoint & pdf versions.

This is an HTML5 version of my Electronic configuration and the Periodic Table activity (no flash plugin is required) 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. It can be previewed on my web site. (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.

Match the hazard warning sign to its description. If correct it sticks. Open the html file by double clicking, et voila. A preview of this activity can be seen on my web site.

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.

For fun

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 animation to jazz up ionic bonding a little: covers sodium fluoride, magnesium fluoride and lithium oxide. Short and sweet. Just double click on ionic bonding.html and it will run in your web browser. If it’s too small, just zoom in with browser controls. A preview can be seen at on my web site.

identify the homologous series from the structural formula

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.

I made a very simple, very introductory presentation on redox reactions. It is intended to be totally entry level.

I recently downloaded the RSC’s very useful “education in chemistry” resource on titrations. The documents are beautifully produced, but I was appalled that the “diagram” column in the equipment tables were low resolution bitmapped graphics. I thought I would produce my own simple diagrams in vector form, so that they can be used at any scale without pixellation. I provide this as a pdf which you can copy and paste from freely, but if you need SVG files , please feel free to contact me via my web site. They may be of use to someone, somewhere.

there are many diagrams of the fractionating column out there. I unashamedly drew on many of them as inspiration for this. However, they are almost exclusively low resolution, bitmapped graphics. I have made my version as an infinitely scalable vector graphic. I then used it to make this labelling exercise. Just for the love of it really. I hope someone might find it useful.

may be useful as a starter or something.
