This year, National 4-H Council has partnered with Clemson University Cooperative Extension, the United States Space Force, Bayer, and Facebook to create STEM activities that are fun and accessible to young people everywhere. The 2021 Challenge theme of space exploration takes youth on an out-of-this world adventure and makes connections to the 4-H pillars?STEM, civic engagement, healthy living, and agriculture. The challenge activities allow youth to develop inquiry, observational, and problem-solving skills while they make discoveries and develop their STEM identities. Galactic Quest is ideal for youth ages 8 to 14 years to spark an interest in STEM and inspire real-world actions. For families wanting to engage with the activities right away or youth working on their own, the Youth Guide can be used as a Quick Start Guide to the challenge.
