Agent Higgs is a great game (developed by TestTubeGames) that will help students learn about particle physics. Your job is to help keep the elusive Agent Higgs hidden, using a growing knowledge of particle physics. Each level teaches students about a new attribute of atomic particles which will be used in that level. New levels also provide ways to continue using previous lessons.
