This hands-on session will display a few inexpensive projects taught in a high school renewable energy engineering class. These projects can be easily modified and cater to students in a wide variety of applications and skill abilities, and utilize inexpensive materials (some of which are free). The first part of the session will showcase example projects, including floating lanterns. In the second half, participants will be able to work in small groups to practice building and flying a floating lantern of their own, as part of a lesson to teach the concept of density.
