Welcome to Perios!!

Meet Chem and Elle the junior Perio explorers.  Help them gather Hydi, Nitro, Stro and all the other Perios.  The faster you gather the Perios and take them home the higher your score!  The more you know about the Perio clans and their regions the faster you can gather them. 

Watch out for the Thermos, Freenerkies and the busy Professor.  He offers hints but stay out of his way.  It may take most of the first Orb to master the gathering technique.  The hardest challenges await as you approach the end of the each Orb.  

Hidden in the game are science lessons for the younger and older students.  Anyone can also have fun testing their knowledge of the Periodic Table of the Elements.  Stay tuned as new adventures are added.  Have fun exploring Perios World!

Parents and Educators:  Perios is a new fun way to learn about the Periodic Table of Elements.
