The Greenest School in Britain

The pupils and teachers at Fairfield School think it's worth looking after the environment! This is what they've been doing:

Growing vegetables

Fairfield School pupils started their own vegetable garden. Both children and teachers plant and water the seeds ( 种子), then I hey pick the vegetables, which are used in school meals. Now they can all enjoy healthy food at lunchtime. "School dinners are tastier than ever before! " says one pupil.

Recycling

The Fairfield pupils don't just bring their books to school—they bring their rubbish too! There are recycling bins (回收箱 )in the playground for cans, plastic bottles, batteries and paper. The teachers give a prize every month to the pupil who's tried the hardest to recycle.

Planting trees

"This used to be one of the least beautiful areas of the city with no green areas, says the head teacher Lynne Johnson. "Now every child has planted their own tree, which he or she looks after during the week. They've made the view from the classroom more beautiful!

Finding cleaner ways to get around

Everyone walks or cycles to Fairfield School! "When the roads are busy, it’s faster to ride bikes than to go by car anyway,” says one pupil. Even the teachers don't use their cars. "We won't encourage our pupils to look after the environment if we don't do it ourselves! " says one teacher.
