World Environment Day

World Environment Day

About this activity

Suitable for all schools and nurseries. Supports the Geography National Curriculum.

World Environment Day (WED) is an annual global event, held on 5th June.

This day is a great opportunity to work with your school travel working group and Explorers/Pioneers Ambassadors to investigate the air quality around your school and consider how active travel can be used to improve it!

To celebrate WED, why not encourage your students to explore the levels of nitrogen dioxide around their school? You can do this by searching for nitrogen-sensitive and nitrogen-loving lichens on nearby trees.  You can download the teachers guide and lichen ID guide or find out more by visiting the OPAL Air Survey website.
