IB chemistry game

Bonding Arcade

Each round asks for two linked decisions: classify the substance by structure, then choose the property that best matches it. The fastest way to use it in a lesson is to let the student talk through the reasoning before you click.

Tutor notes

This works best when the student explains the link between microscopic structure and macroscopic property. If they get the answer quickly, ask for a contrast case: “What would change if this were simple molecular instead?”

Useful prompts

What particles are present?
What is the strongest attraction being overcome?
Would this conduct as a solid, or only when molten?
Is the key feature the bond itself or the overall structure?

How the score works

1 point for the correct structure type.
1 point for the matching property statement.
1 bonus point for getting both right in the same round.
