Project Introduction:
This year's Power Puzzle challenge is about understanding the elements of energy use in a world that uses more and more energy every day. As our world grows and changes, so do our energy needs. The Power Puzzle missions get FLL teams to consider some of the energy choices we have available and how those choices affect the world. With the Power Puzzle project, your team has the opportunity to look at many types of energy choices, analyze the possibilities, and work to improve energy use.
