Last week, the eighth grade went to the Lawrence Hall of Science to investigate the properties of Liquid Nitrogen. The students safely worked with the freezing liquid to manipulate matter and see what happens to different items at about -200 degrees Celsius.
They saw balloons completely contract inward, to only crinkle and fill to the original shape once back at room temperature. They also saw leaves crack and shatter once dropped on a table after being submerged in the liquid, and they saw it completely take the energy out of different elastic items.
It was a SUPER fun field trip!
