2. “The Perfect Breakfast”
Goal: Your goal is to manipulate properties of matter
in order to prepare the perfect breakfast
AND explain what you did.
Description: You are a “scientific” chef and you are
in a cooking competition with a science twist. Your objective is to create a
delicious meal while identifying and explaining all the chemical and physical
changes during the cooking process. Your “cooking” will be evaluated by a
panel of judges with little or no background in cooking but a lot of expertise in
physical and chemical changes.
Judging Criteria: Your ability to identify, provide evidence for, and explain the
physical and chemical changes that occurred during the preparation of the
various parts of the meal.
You will be given the time and laboratory equipment to prepare each of these
items, but, more importantly, you should look at the performance task
questions and be able to answer them as you go along.
