On January 22nd the second graders learned all about physical matter in a fun and engaging enrichment program by the Discovery Museums.
The children investigated the physical properties of solids, liquids and gasses. In this fun workshop, dry ice and liquid nitrogen made learning the phase changes of matter very dramatic. Together, they changed liquid water to gas, shattered flowers and rubber bands, used a banana as a hammer, and even shrank solid metal in just a few seconds. In these photos, the children
experimented with ways to turn solid ice into gas and liquid inside plastic baggies and seeing the affects of sublimation with dry ice in water! At the end of the program, the kids were wowed by liquid nitrogen poured out onto the floor to create fast-running little beads that disappeared quickly!
