The lab is due Friday, March 7 whether you are here or not. Late lab reports will not be accepted. Being absent is not an excuse for not handing in your lab.

Vivien said that her lasting memory of the lab was how it stank. Drew picture around Day 1 setup showing that when you smoke, this is what goes inside of you. You don't want that foul stuff on your skin or your clothes, why would you want it inside your body?

Handed out guided notes for Chapter 2. Went over 1-7, 10, 11, 16, and 17. Students copied from the overhead into their notes. Discussed the difference between elements, atoms, molecules, and compounds. Showed how to count the number of atoms, the number of different types of atoms, subscripts, and coefficients.

Handed out list of 27 elements. Students looked at periodic table and wrote down correct chemical symbol, being careful that the first letter is always capitalized and if there is a second letter, it is lower case.

Students randomly picked an element name and then drew a colorful picture of the element symbol.

Handed out Element Bingo sheets. Students filled in element symbols. Played element bingo. Alex N and Brooke won the first round. Jon won the second round.

Handed out Reading Assignment 2.1, due next time, Wednesday, March 5.
