Happy Atoms 4+

I wouldn’t go so far as to say this app and the molecule set it works with are for kids up to 17 years because by then hopefully they’ve learned chemistry that moves beyond this set. It is still a good support app to complement the molecule kit; together they provide a good basic visual understanding of bonding as well as the structure and significance of common molecules. All in all a great learning tool for kids. The scan features is very limited, however. It had difficulty distinguishing between the yellow Silicon atom and orange Phosphorus atom. It also was particular as to where you selected on the molecule. Fortunately, the app comes with a feature to manually select the correct atom where recognition fails. Good work.

My elementary-aged kids LOVE building molecules and learning about them with this app. I do have to help them sometimes to actually build the molecules, but the instructions are clear. The one major suggestion I have is to add voice options to the names of the molecules. My kids often pronounce the names incorrectly, which hinders the learning value.

The app is good, but I know of argon and helium compounds and when I scan them, it says they don’t know it. Also you should add Boron and Aluminium because those complete the first two rows(arms should be three ionic with bonding sites and colors: boron: letters brown ball pink aluminium: letters pink and ball grey) and add 2 more arms to helium without bonding sites and 8 arms to Argon and the compounds I know of are 1 fluorine+1 argon+1 hydrogen, 2 sodium+1 helium, and 1 helium+1 hydroge(FArH, Na2He, HeH+)
