Solar energy and 3D molecules
Tony Tooth looks at some websites that may be of interest to chemistry teachers.
The solar spark
The solar spark is a content-rich website run by a group of UK academics who all focus on researching solar cells. The website is stuffed with engagingly-written content, much of it aimed directly at teachers.
Highlights include the experiments section, which is superb in its originality. Bored of the work-a-day demos which are the same year after year? Instead, why not make solar cells from drinking straws and raspberries (which contain an excitonic dye molecule)? This nifty experiment is detailed amongst the pages.
