2-D Molecular Models

Covalent Bonding with 21st Century Lewis Dots (2-D Molecular Model Kit)

NEW VERSION (UPDATE FEB 2022) This game allows you to bond atoms together to create molecules using 21st Century Lewis Dot Models. You can build molecules containing carbon, hydrogen, oxygen, nitrogen, and chlorine atoms. Molecules can range from 2 atoms up to 16 atoms! The interface is intuitive and visually pleasing, and sound effects are used to provide encouragement.

Combustion Reactions

Combustion Simulator

This game simulates combustion reactions involving fuels such as methane and propane. Users apply the concepts of Activation Energy and Conservation of Energy as they invest energy to break bonds and release energy when forming bonds. Molecules are represented using 21st Century Lewis Dot Models to form structures such as CO2 and H2O. Potential Energy in atoms and Heat Energy are made visible using "Jewels" as representations of energy.

The Crown Joules

The Crown Joules

This is an exciting game in which students earn points making molecules and gathering "Jewels" of Heat. Using 21st Century Lewis Dot Models, this game is designed to teach students how making and breaking bonds result in energy changes (exothermic and endothermic reactions) We have a few variations on our experiments page: including a Multi-Player and an Android version


Photosynthesis Simulator

Using 21st century Lewis Dot Models, users will create sugar molecules by adding Joules of Sunlight to CO2 and H2O molecules.
The concept of storing Joules as potential energy in molecules is conveyed using visible Jewels that users can invest to break covalent bonds.

Ionic Bonding

Matchmaker: Ionic Bonding

This game will strengthen student skills in creating ionic compounds from common monatomic and polyatomic ions. The concepts of VALENCE are clearly communicated using colorful representations of ions.
NEW! The Latest Version of Matchmaker is now available on the American Assoc. of Chemistry Teachers website! The AACT version incorporates a competition round and medals that reward student achievement.

Double Replacement Reactions using Matchmaker Models

Double Replacement Reactions using Matchmaker Models

Using this simulator, students use interlocking-shapes to investigate double replacement reactions of ionic compounds.
The clear demonstration of ionic valence allows students to gain practice in writing chemical formulas and balancing chemical equations. Positive feedback guides students to the correct products in each scene.

Reactions of Calcium Metal

Reactions of Calcium Metal using Matchmaker Models

This game provides models for the reactions of calcium metal with water and with hydrochloric acid. The transfer of electrons that occurs in these reactions is conveyed using colorful interlocking shapes.

Single Replacement Reactions of Copper Sulfate

Single Replacement Reactions of Copper Sulfate using Matchmaker Models

This game allows students to investigate the transfer of electrons and changes in bonding that occur when copper ions react with zinc and aluminum metals. Positive feedback guides students to the correct products in each scene.

Ionic Bonding

Catalysis using Hammer Toss Models

In this game, students investigate the ability of catalysts (H+ and an enzyme) to increase the probability of productive bond-breaking collisions. Visible energy meters demonstrate the concept of an energy threshold (Activation Energy) required for reaction. Five scenes offer variations on the type of catalyst and the temperature of the reaction mixture.

Ionic Reaction Simulator 2020

Ionic Reaction Simulator 2020

Using this simulator, students will model double replacement reactions that occur in solution.
In particular, this simulator demonstrates the formation of precipitates!
The behaviors of soluble and insoluble salts and the concept of excess and limiting reactants are emphasized.

Electron Transfer 2020

Electron Transfer 2020

This game provides a rich, entertaining model for electron transfer reactions based on the Activity Series. Users can vary temperature and acid concentration to investigate factors that influence reaction rates.

Heat Transfer 2020

Heat Transfer 2020

This game will introduce students to the concept of heat transfer through molecular collisions. Several scenarios are offered, emphasizing the concepts of Energy Conservation and Thermal Equilibrium.

SN2 Game

SN2 Reactions

In this game, students investigate nucleophilic substitution reactions (SN2) by firing a nucleophile at a rotating electrophile molecule. Only precisely aligned molecules with sufficient energy can react!

ChemLEAP Molecular Interactions Sandbox

ChemLEAP Molecular Interactions Sandbox

Using this simulator, students can investigate how changes in molecular speed and attractions affect bulk properties of materials.

Electrostatic Forces Game

Electrostatic Forces

In this game, students must use Electrostatic Forces to arrange particles in specified patterns. The Charge and Mass of each particle are controlled by the user. Solving six puzzles of increasing difficulty will provide students with an intuitive understanding of electrostatic attraction and repulsion.

Cell Model Game

Cell Model

In this game, students play the role of a cell adjacent to a flowing river of molecules (the bloodstream). Players try to import valuable molecules (glucose and oxygen) from the bloodstream while dumping waste products (carbon dioxide) back into the bloodstream for excretion. This game has great replay value, as it is difficult to acheive a high score.

Experiments and prototypes

On the following page are prototypes and failed experiments that were stable enough to run. Some of these are really cool and may be useful, but you may experience a few bugs and problems. However, if you find a lot of value in one of these projects, you can let us know and we just might finish the project. Otherwise, all the code is on GitHub and you are free to finish the project yourself.

TL;DR These are unfinished projects that might be useful

About us games are created by Chemistry Teacher Steven Sogo, supported by a number of talented high school students at Laguna Beach High School. Our mission is to provide free, open-source games and simulations to help teach principles in chemistry and physics classrooms. Our focus is on web-based applications so that all students can benefit whether they have a Chromebook, Apple Mac, or Windows based device. However, we are interested in new technology like virtual reality. Most of these experiments can be seen on the experiments page. All else can be seen here on the main page. If you have any feedback, want to report any problems with out website, or just want to say "thank you," our contact information is listed at the bottom of the page.
