The table contains all the usual information you find in a periodic table of elements, but then under each element, it lists real-world items that contain that element.
This opens up a new avenue of projects for Science teachers where students can not only learn the different elements, but then connect them to real world uses and even explore the method in which the element is applied. For example, assigning a student to report on radon, they'll see it's a key element in earthquake predictors.
I played the Blob (Music) and Cloud-Click (Math) games and they were fun! I didn't try the Algebra or periodic table games. It will take someone smarted than me!
