To any teachers out there who come across my blog, we have a competition:

WIN 30 HP40GS calculators and a data streaming kit (worth £2000)

We are setting up an exemplar STEM teaching room for teachers. We need top quality activities to do in the room, which will be premiered at the Olympia BETT show. We need a detailed exposition of the activity together with any supporting materials (e.g. worksheets etc.) In entering, you give us permission to use the activity (suitably credited) in the STEM room and in a booklet which we will produce with all of the entries and which will be available free to teachers. We would like activities using HP39/40GS or 50G graphing calculators, but any other software which runs under windows (and therefore on the new HP windows 7 slate) would do fine. The activity must be an application which merges mathematics with science or engineering. Send one zipped folder of files with your full contact details to: chris.olley@kcl.ac.uk. Closing date is Friday 9th of December.
