Community Homeschool Investigators

of the River Park (CHIRP) Program


The Guadalupe River Park Conservancy is currently closed through April 7th in accordance with Santa Clara County & State of California recommendations regarding social distancing.


CHIRP is scheduled to return on Monday, April 6th. We will be using a distance learning model to provide at-home classes to our CHIRP families during the month of April or until the shelter-in-place order and restrictions are lifted and it is safe to resume class on-site.


Note: There is no Thursday option at this time; all students must attend on Mondays at the times listed below.

Program Summary

Our engaging Community Homeschool Investigators of the River Park (CHIRP) Program, provides an interactive, outdoor environmental education experience. This is a drop-off program. We utilize our river, famous Heritage Rose Garden, Historic Orchard, and exhilarating park as tools to teach exciting educational themes. Our students build a community with one another by maintaining our classroom garden, and working together with experiments, observations, and other hands-on activities.


Lessons take place outdoors, but will be moved indoors in the case of inclement weather. Our lessons structurally encourage students to form their own connection with nature, while reinforcing environmental objectives and concepts.


CHIRP is proud to be an activity-based, question-driven program with the newest Next Generation Science Standards (NGSS) as a model.


We will be offering Distance Learning Classes during the month of April or until restrictions are lifted and it is safe to return to class.
