Nutrients lab writeup.

Title, name partner, date

Introduction:

What is the objective of this lab? Focus on part B of the lab. Why did you bring your food items in to class? What did you intend to find out? How were you going to find out?

Materials:

List all materials used in lab. Include glassware, chemicals, etc.

Procedures:

• Here comes the tricky part. Keep in mind that the reason you did part A was to find out what each of the chemical tests did. You are going to use that information to explain how to use each test to discover if a food item has a particular nutrient. Imagine I want to use these tests on my Brussels Sprouts. Explain to me how to perform each test, what to look for as a positive result, and what a positive test means (which nutrient does it test positive for?).
• Break the procedures into part I. II, III, IV.

Results:

• This will be your second data table. The one with your analysis of food items. Be sure that the table is labeled clearly. You may only have one item, but put only results your group actually came up with. Make a statement as to which nutrients are in your food. DO NOT INCLUDE RESULTS OF TABLE I IN THIS SECTION.

Conclusions:

• Discuss your results. This should be paragraphs. Are there any nutrients that your foods have that surprise you? Are there any nutrients missing that you expected to find? Are there any results that you have serious doubts about? Support all statements made with clear explanations. I will look for the explanations primarily.
• Explain any source of error in this experiment. This should be error inherent in the procedures you used. ("My partner made a mistake" is not a procedural error) think about what could make it possible for you to overlook a positive result or detect a 'false positive'.
• For each of your foods, what are the implications as to the value of these foods in your diet? Explain fully and support your statements with facts that back it up. What are the ups and downs of the food in your diet?
