Plan to do safety orientation, math basics, and the penny for your thought lab.

Actually did the safety orientation but not the safety quiz, and the penny lab. Students submitted the penny lab. Safety quiz and math basics (both found toward the front of the lab manual) are now due as homework assignments on Thursday. See email for details.

Started with Chapter 2: Classification of matter. Atomic theories.

• PowerPoint on Matter - PDF Handout (6 slides per page) or PPT Slides
• In-Class Activity on Matter - Blank / Answer Key
• PowerPoint on Atoms - PDF Handout / PPT Slides
• In-Class Activity on Atoms - Blank / Answer Key

My suggestions for using this "Files" page and the links posted here:

• Print out the blank copies of each in-class activity. Wait a day or two, then challenge yourself to complete the exercise without consulting any notes. Do the same with suggested homework problems, shown below for each chapter that we cover. Check your answers against the answer sheets, and if you get anything wrong, consult your notes, the PPT's, and the textbook (or ask me) to see where you could have learned how to get the right answer.

Checked into lab drawers. Completed density of water experment and dimensional analysis problem set.

Collected safety quiz, questionnaire, and math basics.
