Winter Wonder Days 2025

Snow outside, science inside! Winter Wonder Days are back at the Science Center. Join us all December long for holiday-themed STEM programming, with an extra-special line up Dec. 26 to Jan. 2!

Family Workshop

December 14, 20, 27, January 3

1 p.m. and 3 p.m.

$5 per person

  • Cocoa Catapults
    • Plan, construct, decorate, and test miniature catapults made of everyday materials and try to launch “marshmallows” into cups of “cocoa.” Staff will also demonstrate a larger catapult to show what the device can do! The miniature catapults can be taken home after the workshop.

Winter Wonder Days Weekend 

December 26 – January 2

  • Fire & Ice Big Science Show each day
    • Experimentation with temperature is taken to the extreme when we battle fire and liquid nitrogen in an explosive demonstration of physics and chemistry.
    • Fire & Ice features color-changing flames, “burning” ice, and a giant cloud finale!
  • Special presentation of Cryoblast on December 31st at noon for “Noon” Year’s Eve
    • Send 2025 out with a bang! We highlight the amazing effects of extreme cold temperatures and what happens when materials change states.
    • Cryoblast features many experiments with liquid nitrogen, ending with a cryogenic eruption that launches plastic balls over 50 feet in the air!
  • Polysnow Hands-on Cart Activity
    • Explore chemistry with a substance that looks like snow after it soaks up a little water!
  • Hockey Friction Hands-on Cart Activity
    • Explore friction and its connection to hockey by examining the structure of a hockey puck and testing a miniature puck on various surfaces.
  • Carpet Skating
    • Experience the science of friction in this indoor skating activity - no snow required!
    • Guests will be able to borrow special “skates” that reduce friction, making it possible to slide on carpet like it’s ice!
  • Gingerbread Scavenger Hunt
    • Track down gingerbread people hidden throughout the museum and receive a prize for finding them all!
    • (Note: the gingerbread in question is not actual gingerbread)
  • Snowflake Symmetry Community Build
    • Add a snowflake to a large collaborative snow-globe and learn about the mathematics behind symmetry and snowflakes!
