The ACR School Program - bolstering science and natural-history education in Bay Area schools

Through our School Program, students are given an education-based, nature experience guided by trained docents who facilitate inquiry and investigation. The docents model curiosity, which leads the students to mine their intelligence, senses, and experience as they ask questions and propose answers based on their observations. As the students hike through a variety of habitats, docents facilitate inquiry-based learning associated with animals and animal signs, plants and botany, ecology and adaptations, food webs, watersheds and water cycles, weather and climate, and much more. Appropriate field procedures are introduced to students that encourage curiosity, inquiry, and appreciation of natural systems and habitats.

This field trip made our Environments Curriculum real to the students. It gave them a close look at one of our local biomes (actually several of them, and that was an important lesson). It gave a wonderful outdoor trip to kids, many of whom have never experienced one before. Fourth grade teacher, Novato

Since the beginning of our classroom and field-based education programming fifty years ago, ACR has provided this free program to more than 250,000 Bay Area children. ACR subsidizes bus transportation costs for classes in under-resourced schools, which eliminates the primary barrier to school participation and ensures that all students can take part. Our School Program consists of the following:

Nature Education Field Trips

ACR’s award winning nature education field trips provide students with pre-field trip classroom visit, a three-hour, docent-led nature hike, and a set of standards-based resources for teachers to develop classroom activities related to the nature-hike content. This program is for children in grades three, four, and five, and cultivates ecological literacy and promotes stewardship of the earth through hands-on, inquiry-based nature education. Docent-led, small group instruction allows for very intimate and personal connections to ACR’s preserves.

Overnight Field Trip Program

Established in 2000, our Overnight Program provides students from under-resourced schools with a deeper exploration of nature in a one- or two-night overnight experience at ACR's Martin Griffin Preserve. Along with a nature hike similar to the Nature Education Field Trips, students engage in bird watching, nature journaling, night hikes, science inquiry investigations, and activities that encourage team building and teach ecological concepts.

Since the overnight program has limited space, classroom teachers are invited to participate after experiencing the day program. If you are interested in the overnight program, notify your docent during your day program or email the MGP Education team.
