What makes CHIRP special?

Our engaging Community Homeschool Investigators of the River Park (CHIRP) Program provides an interactive, outdoor environmental education experience. This is a drop-off program in which we utilize the Guadalupe 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 working together on experiments, observations, and 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.
