Talk about a corny guest speaker! Sixth-grade students in Mr. Fess’ Northstars STEM class received a virtual visit from Bill Johnston of “Kansas Corn STEM.” The students learned all about how Ethanol is made from corn and explored the benefits of using Ethanol when compared to traditional fossil fuels. These students are in the middle of their green-energy unit on Biomass. They are also working on designing and building their own Biomass demonstration projects.
