Chemical engineers use creativity, problem solving and the engineering design process to make things like plastic, oil and foods cheaper and better. One of the tools a chemical engineer can use it catalysis. Catalysis is when a chemical is added to a reaction to make it faster. An inhibitor does the opposite and makes a reaction slower. Reactions might be slower if it is explosive, or produces gas to make it safer. You are in charge of slowing the reaction between citric acid and baking soda to make it safer, but you are on a budget and have many materials to consider.
Chemical Reaction Engineering 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.
Chemical Reaction Engineering 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.
