Pollinator Garden

Supported by NDSU Extension Master Gardeners and Burleigh County Soil Conservation

Our pollinator garden showcases native North Dakota plants that support bees, butterflies, birds, and other essential pollinators. It’s more than a pretty space—it’s a living exhibit that highlights the critical role of biodiversity and conservation. Visitors can spot pollinators in action, learn about the unique and beautiful plants that attract them, and explore simple ways to support pollinators.


Mix & Mess Play Center

This sensory-rich play center invites visitors to scoop, build, observe, and explore. Whether they're observing water flow, experimenting with buoyancy, or mixing mud, visitors engage in open-ended play that builds curiosity, coordination, and creativity. It's a little messy and a lot of fun!


Herb and Vegetable Garden

Explore the herbs and vegetables growing in our raised garden beds, planted by our summer campers! See how food grows, discover the plants that make up our gardens, and ask a team member for a chance to taste test some of the herbs and veggies for yourself.


Musical Instruments

Make some music with our pollinator-inspired instruments! Shaped like a bee, sunflower, and dragonfly, these musical instruments invite visitors to experiment with rhythm and noise. Play a tune and explore sound!


Excavator

Sponsored by Bobcat Company

This exhibit lets visitors explore the basics of hydraulics and machine movement by turning four wheels to control different parts of an excavation arm. By experimenting with each control, visitors can discover how the parts work together to create smooth, coordinated motion. Whether they're trying to scoop and drop material or simply test how far each piece can move, they’re building a deeper understanding of force, motion, and hydraulics—all through play.


Sand Pendulum

Watch motion create art with the Sand Pendulum! As the pendulum swings, its force of motion carries it through the sand, creating unique patterns and designs. Experiment with the pendulum’s movement and see what shapes you can create as it gradually makes its way back to the center.


Whisper Dishes

Step outside and experience sound in a new way. Two giant-dish reflectors use a parabolic shape to focus your whisper from one side to the other. Speak softly at one focal point and the voice will arrive clearly at the matching point. Give them a try before you head into the gallery or on your way out, and discover the science of sound in action.


Solar Tree

Our Solar Tree's panels collect energy from sunlight, giving visitors the chance to discover renewable energy in action. Plug in a device at the Solar Tree and experience the energy transformed from the sun!


Frank Koch Memorial Tree

This tree stands in memory of Frank Koch, Gateway to Science's founding scientist. Planted in his honor, it is a variation of the type of tree he favored for his hobby of woodworking.
