Experimental Design Proposal

Before you begin to design your experiment, a few things to remember.  1)  There are a bunch of videos in the above pages to reference, regarding antioxidants and their function. 2) You need to come up with questions to clarify the UC-Davis procedure handed out yesterday.  3) You need to consider how you will present this information (i.e. poster, video, menu, pamphlet, presentation, blog, etc.)

Experimental Design Proposal must contain the following:

Names of people in your group (list, maximum of 3)

Short paragraph discussing the food you chose and why (3 or 4 sentences) - could be type of food (i.e. carrots) or a category of food (i.e. fruit).  You should site any sources you use (simple web links are good enough).

List of constants and variables - as discussed yesterday, you should limit your variables to ONE.  For example, if picking carrots, you variable could be cooking style (i.e. raw, boiled, sauteed).  You would not want to look at both cooking style and color of carrots (they are not all orange).  If you are inspired by color of carrots, then you would eliminate cooking style and just use RAW for all of them.  

Provide questions concerning the procedure using Folin's Reagent.


DUE TOMORROW!

Mole Conversion Practice Problems

The following link from the "Sophia" websites provide a somewhat rough, but effective tutorial on solving mole conversion problems.  There is an online quiz also to the right of the videos that allow you to check your understanding.  Try them please.

Mole and Molarity - How do we represent "concentration?"

We will continue to look at concentration next week and begin to be more specific with how chemists view the ratio of "stuff to water."  To get ready for the lessons, please review the following videos that describe the mole and molarity.

What is a mole?

Formula Weight, atomic weight, molecular weight

How else do we represent the Mole in Chemistry?
