Kitchen Mysteries

Here’s your chance to investigate and find the answer to your kitchen questions. Cooking is chemistry, but it’s also physics, microbiology, engineering, and more. Select a “kitchen mystery” and uncover the clues to help you solve it. Create a poster to illustrate your answer. You will also be doing a presentation for the class. Be sure to include scientific evidence to provide proof beyond a reasonable doubt.

2.  You may use your poster in the presentation.

3.  You may do a demonstration of your kitchen mystery, if appropriate, or show examples or samples about your mystery, or show a video about your mystery. The video could be a demonstration you did at home or anything else that explains what your kitchen mystery is about.

Grading:

This project is a major grade. 60% will be the poster and all the information included on it. 40% will be your presentation. If you do not present on your assigned day, you will not be rescheduled and you will lose points. If you are absent your day to present will be the day you come back to school.

Have fun and figure out those mysteries!
