Developed with teachers in mind
Use Collisions your way
Designed as modular and interconnected spaces, Collisions can be used flexibly in a flipped classroom, to introduce a lesson, and for extra practice or homework.
Reach the entire class
Collisions couples immersive play with immediate and meaningful feedback to engage students of varying skill and interest levels.
Access meaningful data
Coming soon, a teacher portal will offer performance data to quickly identify students’ successes and challenges as well as their progress.
Free teacher resources
The Game Guides provide an overview of each Collisions content area and highlight the chemistry concepts integrated into the game.
The Student Quests are post-gameplay activities designed to extend student learning and draw connections between Collisions and the chemistry classroom.
