Play the games that you want until about 5 minutes before the end of the period. 
At that point, send an email to theresa@newdesignhigh.com and tell me the following:
1) What games did you play?
2) What are 3 facts that you learned?
3) Did this make you think of any questions that you want to investigate?

If I get an email with all of the questions answered, you get extra credit!

Good Luck!
