About Us

   The 4-H School Enrichment and Outreach projects are designed to enhance classroom education with experience-based learning – ”Learn By Doing”.

Classroom-ready projects teach life skills as well as specific subject matter with the help of 4-H Curriculum.

We have a variety of different topics and curriculum we can cover or provide to you! Many of our programs are aligned to CDOE Standards for easy classroom or after school implementation.

Updated in 2021, we invite you to check out our STEM Loan Out Kits, available through the TRA Extension STEM Loan Out program. We currently have 25+ kits fully stocked with lesson plans, hands on activities, and most supplies. Kits can be checked out for 30 days to classrooms, care centers, and even for home use!

We happily provide many of our programs at low cost or free to our communities! Any cost that is associated with our programs is for supplies.


Please explore our updated listing of online STEM Activities and Kits! STEM Programming is available throughout the Tri River Area!

Glo-Germ/Handwashing – Grades K-5th: Teach your students the importance of hand washing to help to stop the spread of illnesses and germs.

Soil Science – Grades 2nd-HS: Soil is the foundation to plant growth, but not all soils are alike. There are different particle sizes in different types of soils. Students learn to collect different samples of soils from around the area and separate the layers and particles. They also perform a survey of the area’s that soils were collected from and journal what soil combinations serve as the best for plant growth. (See sample video above!)

Kevin the Skeleton – All Grades: Kevin is the newest addition to our arsenal of STEM related items! Kevin is full sized and anatomically notated for any classroom or program discussion on the human skeletal system. Check him out today!
