Atomency vs Collisions Higher Education

Atomency is a browser-based chemistry and physics learning platform with interactive simulations, virtual labs, an interactive periodic table, worked examples, and teacher tools. Its molecule builder displays VSEPR geometry, bond angles, lone pairs, hybridization, formal charge, and polarity. The site lists 29 browser simulations and 17 guided virtual labs, including calorimetry, spectrophotometry, buffer preparation, galvanic cells, and osmosis. Teachers can create assignments with molecule-building tasks, balancing challenges, and open-ended questions, while answers remain hidden in assignment mode. Assignments can be shared through school-approved links or exported for Google Classroom, email, or a district LMS. Atomency maps learning experiences to NGSS performance expectations and organizes content around AP Chemistry, IB Chemistry, and A-Level topics. Core public tools run in a modern browser without installation. Public individual exploration is free at free; official school or district adoption, required coursework, pilots, and managed deployment require a paid license or written authorization.

Collisions Higher Education is a digital game system for teaching and reviewing chemistry in college courses. It aligns with over 55 core concepts in introductory and general chemistry, organized into eight content areas: Radii Trends, Ionization Energy, Acid Strength, Lewis Structures, Ionic Bonding, Energy in Phase Change, LeChâtelier, and IMFs. Each game includes leveled challenges and an exploratory sandbox. Instructors can view student progress and performance in a teacher dashboard, and can use content overviews, quick start guides, formative assessments, and extension assignments. Instructor access is listed at free for US-based college and university educators. Student subscriptions cost $15 a year for a 12-month term; accounts are linked to an instructor’s class, and students register through an invitation URL supplied by the instructor. The product is listed for Android, iOS, macOS, web, and Windows. Playmada has ceased operations, while its FAQ says Collisions HE remains available and free to educators and students as of July 1, 2022. The FAQ also says the company no longer provides email, phone, or training support and directs users to a support forum.
