Speed Review Unit 2 Get into groups Get your “whiteboard” Get a marker Get out notes/ a periodic table/ your lab journal Some one in your group using a phone= no points Prizes 1st place No assignments needed and other good stuff Last place= bad stuff and need +2 assignments 2nd, 3rd, etc Something okay

The first question will be worth up to 24 points! (all other questions are worth 1 or 2 points) So get ready…
