It’s a Gas!

Students in Kylene Utah’s chemistry class have been studying gas laws, the behavior of gases, and how a change in one variable impacts other variables. “One of our lessons involved increasing the temperature of a gas, which also increases its volume and decreases its density,” said Utah. “This is the principle that makes hot air balloons float.” Students worked in groups to design hot air balloons, test their designs, and refine their work in attempts to produce a hot air balloon that would stay off the ground for the longest period of time.
