Collisions is a system of digital games, grounded in the rules of chemistry, that can be used to introduce, teach, and review key concepts in your chemistry classroom.  Collisions is currently available on web, iPad, and Android tablets via subscription.

What makes Collisions unique?

Collisions makes abstract concepts tangible by allowing students to visualize and manipulate the building blocks of matter.

Collisions provides a safe space to make mistakes and learn by introducing content through gameplay.

Collisions easily integrates into your curriculum with 7 robust games and a library of supporting resources.

Demo available on desktop.

The games

Students swipe orbitals to the left to close and check electron fill order.

Atoms game

Build a series of atoms of increasing radii by placing protons in the nucleus and electrons in atomic orbitals while discovering fill order.

Resources to get you started:

   

Student removing an electron from a neutral Na atom to create Na+

Ions game

Form stable ions by attempting to add or remove electrons from any energy level while monitoring ionization energies.

Resources to get you started:

Covalent Bonding game

Build molecules with target geometries by bonding atoms while exploring the relationship between electronegativity and bond polarity.

Resources to get you started:

Students bond together ions to form target ionic ratios.

Ionic Bonding game

Build ionic compounds of specific target ratios using monatomic and polyatomic ions of various charges.

Resource to get you started:

Students build molecules to form various target IMFs.

Intermolecular Forces game

Create LDF’s, dipole-dipoles, and hydrogen bonds by using single atoms or bonding atoms to form polar and nonpolar molecules.

Resources to get you started:

Students remove protons from acids and donate them to bases.

Acids & Bases game

Attempt to add and remove protons from acids and bases to create target ions and molecules while differentiating between strong and weak acids.

Resources to get you started:

Students add and remove energy to form and break IMFs and cause phase changes.

Phase Change game

Cause phase changes in target sequences by adding or removing energy to affect particle motion and to break and form intermolecular forces.

Resources to get you started:

Currently available on iPad, Android Tablets, and the web via subscription.

Developed with teachers in mind

Use Collisions your way

Designed as interconnected modules, 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

A teacher portal allows access to performance data to quickly identify students’ successes and challenges as well as their progress.
