After a lot of number crunching and soul searching, we've decided to close down our physical location...for now.  We may be back once the pandemic is behind us and it's safe to gather together again.  In the meantime, we're pivoting our operations to mobile services. (Yes, we'll be available to bring our programs to you!)  We are incredibly grateful for all those who have supported us!  Thank you from the bottom of our beakers.  Please check out our new offerings and bring a little science into your world!

The Great STEMporium offers wondrous children's activity services. 

Over 50 activities and programs to choose from!

How does it work?

Together, we science!

We are the area's largest (and most fun) indoor science center for kids...and their favorite adults, of course.  We have tons of activities for kids to keep their minds engaged and their hands busy. 

We are just like a restaurant... only... we don't serve food, we serve science projects (and other fun activities)!  It's soooooo much fun!! 


All you do is come in and get a table.  Our Lab Assistants will swing by to give you a basket of fidgets and to take your order.  Kids love to order up the projects that interest them the most - be it a volcano, a laser maze, a coding game, a microscope with bugs,  a lie detector, or any other curiosity-piquing project.  You'll love watching their little faces light up as they discover things for the very first time. 


And don't worry - the mess stays at The Great STEMporium, but the get to keep the memories in your hearts and minds forever.

Don't forget to ask us about field trips, birthday parties, scout badges, home school days, special friends days, Odyssey of the Mind, coding club, evening and weekend science sessions, no-school days, seasonal menu specials, summer science sessions, Sip n' Science, corporate events, team building activities, special events, and more.
