Field Trips 

Field trips are available for 4th grade (some 5th grade) elementary classrooms. Our field trips are funded by various grant organizations and may have specific qualification criteria and are based on availability. To see if your classroom qualifies please contact the education coordinator at 

We use a two contact field trip model* in the education program. This model includes two field visits to one or more of our many partner sites. During these visits students will engage in fun and exciting hands on activities that cover various standards such as habitat restoration, watershed water quality, adaptations, food web, climate science and many others.

*based on funder guidelines some may or may not include a classroom visit
