Astrobiology students are studying planetary formation through the principle of density differentiation, which explains how planets develop distinct layers as they form. In the early molten stages of a planet, heavier elements like iron sink to the center, while lighter materials such as silicates rise to the surface, creating a core, mantle, and crust with […]

After learning about heat transfer, phase changes and phase diagrams, the Chemistry class put it all together to make ice cream using sublimation as a heat absorber. The students cooled down their liquid mixture of milk, sugar, and vanilla with crushed dry ice to create a fun, and slightly carbonated, ice cream treat.
