Digital game for high school chemistry


Collisions is a tablet-based chemistry game where students play with the building blocks of chemistry. The goal is to learn more about how electrons, atoms, molecules etc. affect each other in real world chemistry. Collisions costs between $149/year and $1,150/year, depending on the number of classrooms using the tool.


Students use Collisions to play through several chemistry subject areas. Each area has a separate game, but the games have interconnected levels. In one, students arrange atoms to form molecules. The program gives students a limited number of atoms to work with, and they must use them to form a certain molecule. In the game, atoms interact with each other as they would in real life: In one example in a demo video, a Nitrogen atom will not bind with an Oxygen atom, if only three electrons are shared.

The game provides students with small bits of feedback to help them improve and check their work. For example, the atom-combining game will count the numbers of electrons in a shell to demonstrate to the student whether she has combined them correctly.


Pricing for Collisions depends on the number of licenses:

  • Single classroom: $149/year, up to 35 students
  • Multi-classroom: $395, up to three classrooms; $750 up to six
  • School: $1,150 for use for multiple classrooms in a building
  • District: Custom pricing


According to the company, over 11,000 students are using Collisions in 400+ US classrooms.
