Integration & Usage Scenarios

The Collisions games and supporting resources can be used pre-instructionally, post-instructionally and also for guided instruction in a chemistry course.


Introduction to new content:

  • Engagement
  • Inquiry-Driven Exploration

Assign the early Collisions game levels to enable students to make observations about a new concept and explore on their own before a lesson.

Integration & Usage

I use Collisions as a way to introduce a topic or to have students explore on their own.
Deonna P.
I use Collisions as an inquiry based curriculum material. The app helps students see how chemistry phenomena work.
Diane V.
I’ve been using Collisions it as an intro, guided inquiry activity. I then follow up on the key moments in the game.
Brady L.
I used [Radii Trends] to expose my students to electron sublevels and orbitals since I don’t teach it to them in my curriculum.
Aimee H.
Even if I wasn't remote, Collisions would be valuable. In place of a lab, my students used the IMF module to visualize these forces and how they work/interact. I love it and believe that my students have greatly benefited from it.

Review & Reinforcement

To review concepts with the hope of addressing persistent misconceptions.
Brett A.
I have been using Collisions to review a concept before a test and to help practice while we are learning a concept. It has allowed me to assign fun but challenging assignments that they can do besides just questions online. They are also able to visualize the concepts we are learning, especially when I am unable to demonstrate those concepts how I normally would in class.
Christina D.
I have been assigning certain sims to use as supplements and challenges to material I am providing them (students) remotely. Both [Acid Strength] and [LeChâtelier] were particularly helpful in this effort. My hope is the tutorial and graduated nature of these sims will help students practice the concepts I want them to learn.

Lab Replacement

I used the IMFs game with my chemistry students as a lab activity over the course of two days. One day to complete the levels and the second day to complete the achievements in the sandbox. They had already learned about the different types of IMFs in class. We had just gone to remote learning and were not able to complete the wet labs we would usually complete for this topic so the Collisions provided a great substitute lab activity.
Andrea R.
It’s a hands on way for students to play around with chemical concepts. Since we can’t get into the lab, this is a good way to see concepts at home.
Erik L.


I have assigned [Collisions] as a way to reteach and assess student learning.…
Tom G.
After distance learning was in place, I used it as a lab grade. They have helped the students grasp difficult abstract concepts in a fun, yet meaningful, way.
