Most energy in the world today comes from sources like natural gas and coal, but these are harmful to the environment. Researchers are focusing on creating friendlier, renewable energy sources, like wind turbines, solar panels, or even hydrogen fuel cells. One way to obtain hydrogen for a fuel cell is to use a metal oxide particle to react with natural gas through chemical looping, releasing oxygen, and then reacting with steam to regain oxygen, forming hydrogen gas in the process. The particles continuously cycle through this process, making it efficient.
Oxidation Cycle TEK8 Student Guide
The student handout will be given to all students working on the design challenge. It gives a brief recap of the story, it helps the students identify what they are attempting to achieve, and it recaps the design process.
Oxidation Cycle TEK8 Instructor’s Guide
This Instructor’s Guide provides the instructor additional information on how to run the design challenge with alternatives for materials and test setups as well as information to help make the design challenge a good educational experience.
The Telling the Story Video conveys the societal impact of the student’s research that is the basis for the design challenge and will set the problem-solving context for students.
The Design Challenge Video leads students through the design process. It indicates materials available, states what the criteria are for success and any constraints. It also gives a second ‘level’ of the design challenge that allows ‘early completers’ to move on to a slightly more difficult challenge.
