10. In your notebook: Cornell Notes
Note-taking section: Fill this part in as you read. Things to include: important information from each paragraph, and all the purple vocabulary words and definitions.
Recall section: fill this part in after class. Write down the main points/information, and any questions that you should know, things that would help you study.
Summary: Fill this part in later, after you have studied/reviewed. Sum up the information on this page in 1-2 sentences.

11. In your lab notebook: pages 170-172
Read the section “Am I a Carrier, and What Does That Mean?”
Take Cornell Notes on what you read
Include:
Important information from each paragraph
Purple vocab words and their definitions
