This is a Word document. It is an open notes/fill-in-the-blanks worksheet. I give each student a copy of the open notes, then project the open notes onto my whiteboard, and we fill in the blanks together with the included answer KEY. This is a great way to give a lot of pertinent information without the student having to take copious notes by hand - much appreciated. I then give assignments based on these open notes. The open notes also include color pictures of viruses for a great visual and better understanding of the topic.
