- Abstract:
This educational brief explains the idea that nuclear fusion is thought to be the mechanism by which virtually all of the elements around us are created. Topics include the proton-proton cycle, the carbon-nitrogen-oxygen cycle, and endothermic reactions in supernova explosions. There is also a discussion of the Advanced Composition Explorer (ACE), a spacecraft intended to study the origin and evolution of the elements produced by our Sun.

- Abstract:
Students learn about the periodic table and how pervasive the elements are in our daily lives. After reviewing the table organization and facts about the first 20 elements, they play an element identification game. They also learn that engineers incorporate these elements into the design of new products and processes. Acting as computer and animation engineers, students creatively express their new knowledge by creating a superhero character based on of the elements they now know so well.

- Abstract:
Students research particular types of lasers and find examples of how they are used in technology today. Teams present their findings by means of PowerPoint presentations, videos or brochures. The class takes notes on the presentations using a provided handout. This activity prepares students for the "go public" phase of the legacy cycle in which they solve the grand challenge by designing and producing a laser-based security system.
