Room 6 students experimented with dry ice during Science Club. Students learned that dry ice was frozen carbon dioxide, the gas we exhale and the gas plants use to make food. We discussed the differences between normal ice (frozen water) and dry ice. Water freezes at 0 degrees and carbon dioxide becomes a solid at -78 degrees. Students hypothesised about what would happen to the dry ice when placed in cold water vs hot water. They observed bubbles when dry ice was in water and vapour poured off the water. To show that the bubbles were carbon dioxide (air), we placed water and dry ice in a water bottle and quickly attached a balloon to the opening. The dry ice bubbled and the balloon began to inflate. This week the students discussed the experiment further in class and each wrote about the experiment. We are so grateful to one of our parents, Colleen Brent, for giving up her time to come in and share her incredible knowledge, expertise and enthusiasm with the students each week at S
