Watch this that tells about Lexington’s Big Backyard Program!

The Big Backyard program is a nature-based learning initiative that connects elementary students with their local environment. Trained volunteers lead small groups of students on outdoor explorations, fostering curiosity, observation, and problem-solving skills. This program aligns with the school curriculum, enhancing science learning through hands-on experiences. By partnering with families and teachers, Big Backyard aims to create a love for nature and a deeper understanding of the natural world.

Approximately 2500 children annually participate in these outdoor explorations, guided by around 800 enthusiastic volunteers. These short, 30-60 minute walks, conducted during school hours, provide a unique opportunity for students to connect with nature and develop a sense of environmental stewardship. The program not only benefits students but also offers volunteers a chance to support classroom teachers and bond with their own children.

Inclement Weather and School Policy

Families are notified by their teachers and/or big backyard team of upcoming walks and instructed on what children should wear and how to prepare for a walk. Proper clothing as well as sunblock and insect repellent is suggested depending on the season.

Students go on walks as long as it is not raining, the temperature is at or above 18 degrees Fahrenheit with the wind chill factor and there is not a heat advisor in effect. 

Note:  Volunteers and families are notified of any postponements or cancellations due to weather, via email, before a walk takes place. If you still have questions the day of the walk please contact your school's office.
