RAIN CHANGES FOR OPEN HOUSE April 22nd
Due to predicted rain and thunderstorms on Saturday April 22nd, we are planning to:
- END the Open House at 1pm (when weather is supposed to get worse.)
- For ticket holders of 10a-1p session, you can come as planned.
- For ticket holders of 1p-4p session, you can come to the MORNING SESSION 10a-1p!
We will plan to do as many activities as the weather allows, but there may be a few showers in the morning.
We will move some programs inside if possible and have a tent over the campfire for S’MORES!
Please bring rain gear and sturdy shoes.
The Outdoor Lab is wonderful on a warm, cloudy day. Students go outside for field trips no matter the weather. (Some animals venture out and fish seem to be hungrier;)
Thank you for understanding.
Mike Maleski, President

What is the Outdoor Lab?
The Phoebe Hall Knipling Outdoor Lab is a 225-acre facility that provides science and outdoor education to the students of Arlington County Public Schools. In this natural classroom, urban youth — often for the first time — can run in a meadow, climb a mountain, hike beside a stream, or fish in a pond. Up to six classes per week visit the Outdoor Lab, some overnight, and there are three week-long summer camps.
Each year, the Outdoor Lab provides hands-on outdoor and environmental education to more than 10,000 students, from elementary grades through high school.
The non-profit Arlington Outdoor Education Association (AOEA) owns the land and buildings and partners with Arlington Public Schools who provides the teachers, buses and science programming at the Outdoor Lab.
Here’s a video for the Outdoor Lab’s 50th anniversary produced by APS’s AETV Green Scenes.
