Lab 2: ProtocolIn today's lab you will learn how to use a micropipette. You will set up experiments to try and predict the glycemic index of unknown food items and you will continue analysis of the diabetes data.
Exercise I. Pipette Challenge Exercise II. Predict the Glycemic Index Exercise III. Continue Analysis |
Please keep the following in mind to increase the likelihood of both accurate and precise measurements in lab:
Review the parts of a micropipette:
|
At the beginning of lab, your instructor will demonstrate how to properly use a micropipette. Watch carefully and follow along. |
Your task in Exercise II is to develop a series of tests, using chemical indicators, to predict the gycelmic index score of unknown food items.
For shorter experiments like this one, you will be provided with an Experimental Notes and Data template. Each template is lab specific, follows the steps of the scientific method, and is meant to approximate what you would record in a lab notebook as you work through each experiment. Every lab member needs to submit one in the post-lab and every member should save them in a folder labeled BIOL 121 Lab Notebook. Materials: Your Tool Kit
Procedure
|
Go back to Lab 1. We are not ready for graphing yet!You left off at this step at the end of lab 1. Let's pick back up and continue. Exercise II might have given you some new ideas? Continue Results Analysis (from last week). Use the resources available to complete hypothesis testing for both of your diabetes data research questions. Be prepared to show your instructor Excel tabs with the data used and results for each test.
Procedure: Create graphs of your data & start your technical report
