Primary school children are helping to map climate change in the UK with daffodils.
Pupils at St Nicholas School in Old Marston, Oxford, will record when their bulbs sprout and flower.
Then, by comparing their timings with other schools across the country, they can build up a picture of how our climate is changing.
Zoe said: “We had great fun planting the bulbs, and we enjoyed showing the younger children how to plant the bulbs in pots.”
Meriel added:”We learnt a lot about climate change.”
The project was spearheaded by the National Museum Wales, and 113 schools are now taking part.
The Edina Trust, based in Yarnton, enabled 12 schools in Oxfordshire to take part by supplying bulbs, as well as other weather-monitoring equipment such as thermometres and rain guages, and even a camera.
Carol Kelsey, a teaching assistant at St Nicholas, said: “It linked in with our eco group and climate change is a pertinent issue. It also links with our science lessons and teaches computer skills.”
Each Friday, youngsters will upload their data for the week onto a national database.
Edina Trust administrator Rose Blake said: “It is wonderful to see so many pupils across Oxfordshire taking part and becoming so involved in the environment.
“It has been particularly rewarding to see enthusiasm for the project.”
