Reasons to register for Collisions HE

Collisions HE is an ideal instructional tool, as well as a learning and practice resource, for college and university students.

Collisions HE is aligned to Introduction Chemistry and General Chemistry for higher education courses.

Collisions HE contains 8 content areas including: Radii Trends, Ionization Energy, Acid Strength, Lewis Structures, lonic Bonding, Latent Heat, LeChâtelier and IMFs.

Within each topic area there are between 12-20 different levels where various concepts are covered. View our Chemistry Content Integration Guide.

College Instructors can register for a free Instructor Collisions Higher Education account.

Students can register for a free Student account via the URL class link provided by their instructor.

As a College Instructor, you will have access to our library of college-level resources and assessments. You can view and download all of our free educator resources once logged into the Instructor Portal. Resources include:

  • Chemistry Content Integration Guide: Each Collisions game is designed to introduce students to key chemistry concepts and objectives through interactive gameplay and scaffolded leveling. To best align a specific Collisions HE game with a topic that you are teaching, please refer to this list. This is a great resource to use when mapping Collisions HE throughout your chemistry curriculum.
  • Content Area Overview: Each Content Area Overview provides a detailed look at each Collisions content area, highlighting the chemistry concepts integrated across each of the levels. This is a great resource to use when mapping Collisions HE throughout a particular unit.
  • Educator Quick Start Guide: These content area specific guides provide samples of guided questions and student prompts designed to incorporate each Collisions HE content area into your chemistry lectures and tutorial classes for both pre-instructional and post-instructional use.
  • Formative Assessments: These documents are fillable PDFs for student practice that directly align to each Collisions content area. They can be used to analyze student understanding or to help reinforce a specific concept.
  • Extension Activities: These are analysis activities that can be used to extend learning by prompting students to draw connections to additional chemistry concepts covered in Introduction to Chemistry and General Chemistry courses. In these activities, students ‘collect data’ in the Collisions HE Sandbox, and analyze the results to draw conclusions about a concept.
