Class Activities
Today in class we focused on a infoquest about Diabetes, and evaluating whether statements are true, partially true, and false. We went to the library, and were working from reliable sources. I don’t need full MLA citations- but I do need to know why you are saying the resource that you used is reliable.
Using encyclopedias, references books and the internet, research the following topics and
comment in detail on their validity. You may research with another person, but you need to
pass in your own answers. Cite your reference(s) for each topic, use only reliable resources.
Below each reference, write how you know it is reliable.
1. Insulin is a hormone needed to move blood sugar (glucose) into cells, where it is stored and later used
for energy.
