Education “of Tomorrow” For the Fun of It

Physically touch a spacecraft Playground tracking events Chase a FAST moving object Control a camera 300 miles above Talk to people a 1000 miles away

For the Inspiration of It Exciting tool to give STEM a tangible purpose “How does it work?” “How can I do that?” Student Payloads

Class photos, names, audio clips Sights and sounds of the state Sensor systems (future)

The Curriculum Aspect Aligned with STEM standards Spiral connection Teachers co-author curriculum

Building for the Future K-12 Collaborations Statewide KySat conferences
