If you are looking for STEM education resources for youth between 5-13 years of age, the Jr. Camp Flight Pack from the Academy of Model Aeronautics (AMA) could be the perfect resource for you.
In my experience, most people are highly interested in the subject of flight. The Jr. Camp Flight Pack includes everything needed for youths to explore a diverse collection of flight principles. The Jr. Camp Flight Pack was developed by the AMA, the world’s largest model aviation association; people who are most passionate about aviation, especially model aviation.
The AMA created a training video to help adult leaders prepare for working with kids. Happy flying!
