| Are All World Maps Incorrect? | Geomatics will offer two activities! First, we will use Avenza to teach folks how to navigate campus with georeferenced maps. We will have prizes set up across campus and folks will navigate to find the 'geocached' prizes! Next we will take a look at a 3D visual of the world, and examine how we can flatten it onto a 2D surface. We will discuss if this is mathematically possible, and what the implications are when flattening a globe. | AT-127 |
| Astronomy | Learn about planets, gravity, stars, and telescopes. | AT-106 |
| Balloon Powered Race Cars! | Unleash your inner engineer and get ready for some high-octane fun! In this exciting hands-on activity, you'll build and race your very own balloon-powered car. Using simple materials like wood, straws, wheels, and of course, balloons, you'll learn about the fascinating principles of propulsion and aerodynamics in a fun and engaging way. | AT-129 |
| BeLEAF it or Not-Forestry & Geomatics | Explore tree cones and leaves, maps, and ATVs. Visit stations to learn about the science behind forests. "I can have a job where I spend the day hiking in the trees with my dog?" BeLeaf it or not! | AT-127 |

Using a traditional Japanese technique called Gyotaku, you'll make your own fish print using real fish or molds — and yes, you get to take it home! While your masterpiece dries, stick around to check out what’s inside a fish. We’ll have real specimens to explore their anatomy and scales up close. It’s a hands-on, fun-for-everyone activity where science meets art — perfect for curious minds of all ages. | HU-125A |
