Test 4: Viruses & Bacteria Test

You and your table are all a team. You have a specific team color.

You also have ziploc bags with answer key cards. I will post the question and you have 30 seconds to decide with your group on an answer.

The team with the most points at the end of the game win a surprise from Mrs. Dennis tomorrow before the test.
