Since October 2005, school scientists across Wales have been keeping weather records and noting when their flowers open, as part of a long-term study looking at the effects of temperature on spring bulbs.

Participating schools planted daffodil and crocus bulbs in October and took weather readings from November to March. They entered their weekly weather records and the flowering dates and heights of their plants to the Amgueddfa Cymru - National Museum Wales website.

The long-term study...

Our climate and seasons are changing. Over the next 10-20 years (and hopefully longer) we want school scientists to show how climate change is affecting flowering dates for spring bulbs. In the short term there is plenty for schools to study. This project is aimed at years 3 to 6 and draws on numeracy, literacy and digital skills. The project compliments elements of the national curriculum for Science, Geography, Maths, Art and ICT. It also supports the four purposes of the Curriculum for Wales by inspiring pupils to be confident, creative, ambitious and ethically informed.
