I found this really sweet powerpoint presentation on soil composition that explains the composition of soil in a simplistic but fun way. Click on www.school-portal.co.uk/GroupDownloadFile.asp?GroupID=38264&ResourceID=95544
The programme can be frozen at any stage by clicking on the button with the two vertical bars (II). This allows the teacher to explain the process step-by-step.
