2012 Student Showcase
Samples of work done by 6th graders in the year long 

Science games and other games
These games were built using Scratch, a computer programming language from MIT. 
Students were first given a series of small programming challenges - moving a sprite with arrow keys, creating a maze, etc. The programs were later converted to a simple Science theme based game. Since this was done during the last few classes, many students were not able to add more details or finish them.  Some games that were finsihed were uploaded to the Scratch web site, and are available below.
