The Munroe Elementary School PTA hosted a COSI On Wheels Day for all third-graders on Jan. 27. Students first attended an all-grade assembly where they unraveled a chemistry mystery using science to solve the clues.

The third-graders then participated in nine hands-on stations, exploring different scientific principles. Fun activities included learning about buoyancy, using microscopes, writing with invisible ink (and making it appear), testing pH, predicting the results of chemical reactions, learning about solids, liquids and gasses, and making slime!
