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.

Graphics for GCSE physics waves topic

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

In the past I have used a physical water circuit to explain to groups concepts such as potential difference and current. I wanted my own diagram of this, so produced this. Someone, somewhere might find it of use.

I have added the new definitions to the SI wheel of units. Possibly for display in your lab.

There is a beautiful graphic depicting this on the internet. However, it is a bitmapped graphic . I have adapted it as a a scalar graphic, with improvements. Please get in touch if you want an editable version.
Hooke's Law simulation

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. Please note: in order to provide a rich interactive experience, my interactive 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. ©D&D production

A simple wordsearch on energy & electricity. Word searches help concentrate on scientific literacy and aid concentration. they are good summary activities and for revision. I have tried to make this attractive and efficacious in that it uses only one side of A4.
