Discover the Science of Flight!

Get ready for a day of high-flying STEM adventures at the Science Mill! Explore the science and engineering behind flight through exciting hands-on activities, live demonstrations, and inspiring career connections.

Learn how helicopters spin, airplanes soar, and even maple seeds glide through the air as you investigate the forces that make flight possible. Throughout the day, you'll build, experiment, create, and discover alongside real aerospace professionals.

Whether you're an aspiring pilot, engineer, scientist, or simply curious about how things fly, STEM Flight Fest offers an unforgettable day of exploration for the whole family.

Crazy 'Coptors!

Design, build, and decorate your own rubber-band-powered helicopter! Discover how stored energy and spinning propellers create lift as you launch your creation and watch it soar.

Bernoulli and You

How can something as heavy as an airplane fly?

Discover the science behind lift as you explore the Bernoulli Principle and Newton's Laws of Motion. Learn how the four forces of flight—lift, weight, drag, and thrust—work together to keep airplanes in the sky.

Fan-Tastic Forces

Become an aerospace engineer as you experiment with different materials and designs to see how the four forces of flight affect performance.

Test, observe, and compare which creations soar the farthest during exciting live demonstrations.

Spiraling Spinners

Nature is one of the world's greatest engineers!

Discover how maple seeds use drag to spin gently to the ground, then build your own Spiraling Spinner and explore how biomimicry inspires modern engineering and technology.

Meet STEM Professionals

Meet real scientists and engineers working in aerospace and space exploration. Hear their stories, ask questions, and discover the many exciting career paths available in STEM.
