Abstract: | the field course described has recently been piloted with a sixth-form group and is currently undergoing a more extensive evaluation. It consists of written materials for students and a teacher's booklet giving all the necessary techniques, lists of apparatus, and practical hints. The course aims to estimate the energy flows in a woodland ecosystem by means of a series of practical sessions involving field and laboratory investigations and calculation. It is hoped the course will eventually be published and made generally available. designed with the non-ecologist teacher in mind. By using the supporting materials any teacher should be able to run the course. |
