About this event


We're sorry, but this activity is over. The last meeting was Friday, March 3, 2023.

Discover the special place witness trees have in the history of Illinois. Used by surveyors in the early 1800s, witness, or “bearing” trees, were sought out as landmarks for creating the earliest state land surveys and plat maps. Some of these trees are still standing today and can be used as a lens to bridge the gap between science and social studies, as well as connect us to our past. Join educators at St. James Farm in Warrenville where science and history converge. Through a variety of activities, learn the role these trees played in the urbanization of Illinois, why they are still important today, and how oak trees are critical to local ecosystems. Then complete a STEM-based learning project to catalog potential witness trees. Take ideas back to the classroom to get your students engaged in similar data collection projects at school. Major portions of this program will be outdoors, and participants should dress for the weather. Registration is free.
Water bottles recommended. Dress to be outside. A lunch break will be provided. Bring your own lunch.
