Third graders at the Rocky Mountain Classical Academy had the chance to experiment with the solid form of carbon dioxide—dry ice—on Thursday, right in their own classroom. The day started off with a Cool Science show about solids, liquids and gases in the school auditorium. Students’ eyes lit up when a spoon made of the metal gallium melted faster than an ice cube in warm water. This was just one of the many demonstrations about the ever-changing forms of matter in our world
After the show, the kids had the opportunity to get some hands-on experience with dry ice. The third graders were able to see (and taste) what happens when dry ice carbonates apple juice, play with soap bubbles formed from carbon dioxide, and handle dry ice with spoons and gloved hands. They also learned an important new word: sublimation! This is when a solid becomes a gas.
Everyone, even the teachers and parents, had an amazing day learning about the science behind solids, liquids and gases. Perhaps more than a few students were captivated by the exciting and cool world of scientific study after such entertaining activities, and parents learned some easy ways to spice up their child’s next birthday party.
