Join us at Severson Dells for these family-friendly, open-house style events. Each month will have a different nature theme full of hands-on, minds-on activities for guests of all ages to participate in. Weather permitting, there will also be guided hikes.


All Science Saturdays are FREE!


Most Science Saturdays are 10 am to 2 pm except when specified.

Experience the outdoors safely! We'll teach you all about shelter-building, how to identify unsafe plants, fire-building, navigation techniques, wildlife tracking, and more!

This Science Saturday invites local Indigenous groups to utilize Severson Dells to teach community members about stewardship of nature and Indigenous culture & traditions.

Let's move this party underground! Enjoy hands-on science activities, nature crafts, and fun games as you discover underground habitats, roots, and creatures through all-day family-friendly adventures. 

Prepare to get closer to nature than you ever have before! Some of the most fascinating organisms are smaller than your fingernail! Join us to discover Micro-Nature!
