Cool Science Carnival Day

Picture

Last updated 5-Sep-2025 (be sure to refresh your browser)

For many of our most devoted young fans Cool Science Carnival Day for Kids IS the festival!  Carnival Day at UCCS (even though it wasn't called that yet) actually began in 2009, and was such a huge hit that it was a no-brainer when we decided to expand it the following year to create the multi-day celebration of all things STEAM (Science, Technology, Engineering, Art & Math) that we all enjoy now.

Cool Science Carnival Day for Kids at UCCS is truly STEAM on steroids!  As always there will be several exciting demonstration shows, including a  Chemistry Magic show from the U.S. Air Force Academy with color changing "potions" and explosions!

​Planning Your Visit
  • Pre-Registration: Carnival Day is FREE, but please pre-register online to help us to know how many people are coming, kid's ages and how you found out about the event. It only takes a couple minutes.
  • Pre-Arrival: If you like to prepare for big events in advance, you can download a copy of our Carnival Day Map/Flyer (coming soon) to plan your route through all the fun activities.
  • Best Time to Come: We expect about 8,000 people to attend throughout the day, so it's always best to arrive earlier.
  • Parking: All campus parking lots are FREE on Carnival Day, but fill up quickly.  Check the campus parking map for more information.
  • Arrival/Information: Our activities will be spread across much of the UCCS Central (main) campus, inside and outside the University Center (UCTR), Centennial Hall (CENT), Gallogly Events Center (GEC), Osborne Center (OCSE), and the new Anschutz Engineering Center (AEC).  We will have maps and volunteers to assist you at the main entrances to each of these buildings, but a good place to start is the University Center Lower Plaza Information Table (just to the right of "KFL" on this campus map).
  • Food:  We expect the University Center food court, Cafe 65, will be open as well as the coffee shop, also in the University Center (exact times for each coming soon).  The variety and quantity of food available may be limited, however, so you may want to bring your own snacks.
  • Weather:  We'll go rain or shine.  If it is raining, snowing or extremely cold we will move most of the outside activities indoors, and of course the majority of our activity stations are already indoors.
  • Social Media: Help us spread the word.  Please share this page with your friends (Facebook "Like" and "Share" buttons above) and share your comments and photos with us on our Carnival Day Facebook event page (and be sure to Like us on our Facebook page too).  We're also on Instagram and TikTok.  Use the hashtag #CSCSF.  BTW we post a cool STEAM activity that we like from the internet every day on our Facebook page- check it out and give us a Like!
  • T-Shirts: The official 2025 Cool Science Festival T-shirt will be announced soon. Youth and adult's sizes will be available only at the University Center (UCTR) Lower Plaza Information Table (just to the right of "KFL" on this campus map) for a donation to Cool Science ($15/youth, $20/adult, cash only).  
Some T-shirts from previous years may also be available for a reduced donation.

 
* Please help us keep this event admission FREE *

​Make a suggested donation of $2/child ($5/family)

​Donate at Information Tables (cash only) or online through ColoradoGives
