Community Homeschool Investigators

of the River Park (CHIRP) Program


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.

Shifty Business

November Classes


Becoming an Eco Warrior
Dates Offered:

Ages 5 – 8: Monday, November 26

Class Description:

This week, we will be applying concepts we have learned during the series. We will begin by wrapping up our ongoing weather chart and talk about the patterns we observe. Through the examination of these patterns, students will create hypotheses for future patterns they expect to see in the surrounding environment. Additionally, we will take a critical look at our backyard classroom/garden to strategize ways to make it more sustainable using what we have learned.

Topics We Will Cover:

Weather patterns, sustainability, sustainable gardens
