This simulation provides practice for beginners in balancing chemical equations. Introductory activities include separating a water molecule and making ammonia (a compound composed of sodium and hydrogen). The user clicks up or down arrows to add/delete atoms, while bar charts and balance scales are displayed to show when the equation is in balance. Next, apply what you've learned and play the "Balancing Game", with three levels of difficulty.

Editor's Note: The game-like nature of this activity not only gives students practice with chemical equations, but goes much deeper. By viewing the distribution of individual atoms in real-time charts alongside the equation, the learner is building a basis to understand conservation of matter and chemical interactions.

See Related Materials for a link to downloadable lessons and student guides developed specifically for use with this PhET simulation.  

This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET).

Topic: Particles and Interactions and the Standard Model
Unit Title: Molecular Structures and Bonding

The game-like nature of this simulation gives students practice with chemical equations, but goes much deeper. By viewing the distribution of individual atoms in real-time alongside the chemical equation, the learner is building a basis to understand conservation of matter and chemical interactions. Teachers of middle school and Physics First -- look above under Lesson Plans for an excellent teacher-created lesson to go with this simulation.
