Dec 2015 Books Contest Continues: Starting only at recess on Monday, post a suggestion of how chemistry could help people in the future. Although the first 3 suggestions will each gain 2 points, people can keep coming up with ideas throughout the day. The most original idea between the beginning of recess and 5 PM, will get 7 points. If you don't have Facebook, just email me.
