How STEM projects make a better world:
Science, Technology, Engineering, Math. (STEM) It's the very foundation of our modern world. Without
inventors, theorists, engineers and scientists, we'd still be living in the stone age, and the challenges facing
our world today make STEM skills even more important than ever. Hands-on experience with real-world
projects gives kids a kick-start on life too. It shows them that math and science are more than just abstract
equations on paper, they have applications in the real world that are exciting, fun and important. It gets the
kids outdoors, away from the TV and video games, and it is great mental cross training regardless of what
field of work they eventually go into. Our kids are the future, and smarter kids make a better future for
everyone. Help make a better world. Get a kid started with a STEM project today.
