About the Yard Games
The Crystal Cave is part of the Yard Games, our collection of middle school science games. Designed as playful introductions to complex topics, the games are online and free to play.
We created Crystal Cave with our amazing partners at UW-MRSEC and Wisconsin DPI. Our team relied on the expertise of teacher fellows from across Wisconsin to help conceive, design, and test the games.
