Happy Atoms is the physical and digital teaching tool that lets you discover the world of molecules in an intuitive, hands-on way! This interactive learning tool combines a digital app with a physical modeling set that lets students from 4th grade through college approach chemistry from a different angle.

Happy Atoms requires the use of the Happy Atoms modeling set for full play. The sets are available at and at many educational retailers!

Chemistry is an incredibly important subject that many students never fully grasp. Knowledge of chemistry is necessary to solve many real-world problems, but the way chemistry is taught now often fails to capture students’ imaginations, discouraging experimentation and discovery.

Happy Atoms aims to change that by offering a chemistry learning experience that sets itself apart.

* See the difference between elements
* Feel the forces that bond them together
* Experiment with ways to combine them
* Discover the relationships between molecular structure and properties

More molecules please?

I know ten more molecules have been added but i want more molecules to fill the map and try to make a new set of atoms with more elements like iron,aluminum,and boron.

Great but more!

I’m not getting any better molecules. I want some more stuff. You know? I want some more Noble Gases. You are not making enough of the other atoms. Maybe some of the more explosive ones would be more interesting ones.

Fun, addictive, instructional - AWESOME!

This app is an essential companion to the Happy Atoms experiment kits from Thames Kosmos. It is incredibly well done, one of the best educational apps I have ever seen. Our 10 year old got the kit as a gift, and his mom and dad are still awake trying to get “one more molecule”!
