This summer saw the first running of “Mayfly in the Classroom” at Brantwood School in Sheffield. I was so impressed by the Year 8 pupils (and their teachers, Mrs. Skidmore and Mr. Jones) who got completely involved with the whole exercise. The beginning of the two-week experiment saw lots of puzzled faces (at what possible importance a lowly insect could have). Puzzlement was also followed by a certain degree of surprise that significant proportions of the lessons would be made up of what the pupils thought and felt about the issues raised. By starting with students collating and prioritising basic requirements for almost all life on the planet (oxygen, water, nutrition and shelter/habitat), we were then able to examine how the simple plastic aquaria (made from fizzy drinks bottles) supplied all these needs. This led on to the apparatus construction and the introduction of the nymphs to their new homes... Throughout the experiment, students assumed the duty of care towards the insects....
