Discovery Room

The Discovery Room will be closed for for cleaning January 9, 10 and 11

Water, nature, space, and more! Explore the Discovery Room with your young scientist. Immerse yourself in science learning through play. Research shows that children grow socially, academically, and emotionally in play-based settings like the Discovery Room, so come and learn through play together! The Discovery Room is open to everyone, but is specially designed for young learners ages 1-8 and their families.


Learn about water on our planet at the Wonderful Waters exhibit as you scoop and pour water in the city’s water reservoir, on the mountaintop, or fill the rain cloud. Observe an axolotl in her freshwater environment, and observe life on the reef in our saltwater aquarium. Be sure to say hello to Dori and Nemo!

Space Rocket
Pretend to be a NASA engineer on earth, or put on an astronaut helmet and climb aboard the SLSC Harmony rocket ship. Prepare for liftoff and imagine you are flying to the moon, Mars, or beyond. Keep in touch with Earth on the tv screen and microphone. When you return to earth, exit the rocket via the slide!

Animal Clinic
Imagine being a veterinarian and care for the animals in our hollow tree clinic. Put on a lab coat and stethoscope and you’ll be dressed to help the animals. Observe live Rainforest cockroaches and Madagascar Hissing cockroaches. Ask a staff member if you’d like to hold a cockroach.

And more!
See in tiny details with the microscope, create constellations in the Star Room, play with your shadow in the Shadow Theater, and explore air movement at the Wind Tunnel. Math and engineering activities are changed regularly. Get creative in our Makerspace and learn to use a variety of materials in unique ways.

Space is limited to 50 people. One adult chaperone is required for every 4 children.
