Howarth, Sue (2004) Snail Shells and Acid Rain – an Alternative to Marble Chips and Acid. School Science Review, 85 (312). pp. 47-56.Full text not available from this repository. (Request a copy)
An original project carried out by a UK year 9 (13–14 year-old) science class is described. The reaction between acid and snail shells was investigated, and the effects of different acids, acid concentration, temperature and shell size were studied. The results were related to the effects of acid rain on snails in the wild. Students responded with interest and the project not only encompassed many chemical and biological ideas but encouraged teamwork and the development of good practical skills. It could equally well be a useful project after key stage 3 or the basis of GCSE coursework.
