Virus Basics

http://library.advanced.org/23054/

This is where you will read what a host is, how viruses infect, types of infections, and what exactly is an infection. The reading is technical, so there are guidelines given here to help sort through the most technical reading. General understanding is the goal. Each section is short. This is a GED activity.

Take notes on paper while you read. This will help you to sort out the main points of each section. Note taking experience will help you in a job, in college, even in the doctor's office. If you can take notes that pick out the main points of information given, you will have a useful tool in life.

Ask permission to print out this page so you can read the directions below once you arrive at the virus site.

If you are working on this site alone, stop after each section and decide what the main point of that section is. Try to make a picture in your mind of what is being said. Decide what you think is amazing in each section. Do you have questions? Ask your teacher or someone else who could read this with you. Then, make a list with colored pencils or markers of an amazing fact for each section you read. Or you could draw a picture of each one or just THE fact that was most amazing. Have fun. Infect yourself with virus knowledge!
