13 Apps for Kid Scientists

Toca Lab
Toca Boca makes a multitude of fun and educational apps, and Toca Lab is one of their most robust. Kids can experiment on over 100 “elements” with heat, ice and more to create something new to examine in the lab.
While the game isn’t scientifically accurate, it does encourage experimentation and discovery, as well as introduce the names of the elements, making it suited for kids who are too young to understand more complicated chemistry concepts.
$2.99; recommended for ages 6–8; available on iPhone/iPad and Android.
