OMSI will be coming to Greenway for TWO assemblies!!! K-2nd grades will have their assembly 12:15-1:15 and 3rd-5th grades will have theirs 1:30-2:30. Students help OMSI staff conduct experiments that vividly demonstrate the predictable (and sometimes unpredictable!) reactions of matter, including some that have explosive results. Topics include nature of chemical reactions, physical vs. chemical changes and safety. We are pumped!
