Done w/warm-up? Get started on the homework.

9. Chemistry Wednesday 8/23/2017 HOMEWORK: None tonight.
NOTE: Late work gets no stamps, but it does get some points when you turn it in, so get caught up if you’re behind.
Also, bookwork completion is required for re-takes of tests.
WARM-UP: Keep following the warm-up rhythm from now on:
Skip a line, date, question, answer
Q: Compare and contrast theories and laws.
STAMPS: 1.3 notes, 1.3 section assessment (#’s 16-25, MUST show evidence of self-correction)
Done w/warm-up? Work ahead in chapter 2.

10. Chemistry
Thursday 8/24/2017
Sit where you sat yesterday. The seating chart is official now.
HOMEWORK: 2.1 reading notes
WARM-UP: (Remember: Skip a line, date, question, answer.)
Q: Who would a farmer need to collaborate with in order to develop a more effective insecticide?
STAMPS: 1.3 section assessment (#’s 16-25, MUST show evidence of self-correction). (No more extra time on due dates after today. Get work done on time from now on.)
Done w/warm-up? Get started on the homework.

11. Chemistry Friday 8/25/2017 HOMEWORK: 2.1 section assessment
WARM-UP: What kind of variable should an experiment have only one of? Why?
STAMPS: 2.1 reading notes
NOTE: Starting with today, you can get stamps for late work only if you have proof of a valid excuse.
Done w/warm-up? Get started on the homework.

12. Chemistry Monday 8/28/2017 HOMEWORK: 2.2 notes
WARM-UP: What are the extensive and intensive properties of a 68 cm x 56 cm x 3 cm piece of white styrofoam that has a mass of 173 grams?
STAMPS: 2.1 section assessment (#’s 1-8)
Done w/warm-up? Get started on the homework.

13. WARM-UP: What are the extensive and intensive properties of a 68 cm x 56 cm x 3 cm piece of white Styrofoam that has a mass of 173 grams?
68 cm x 56 cm x 3 cm = “dimensions” = extensive property
68 cm x 56 cm x 3 cm = “volume” = extensive property
What is the Styrofoam’s volume? Calculate it!
68 cm x 56 cm x 3 cm = 11,424 cm3
white = intensive property
“Styrofoam” = polystyrene = (C8H8)n = intensive property

15. WARM-UP: What are the extensive and intensive properties of a 68 cm x 56 cm x 3 cm piece of white Styrofoam that has a mass of 173 grams?
68 cm x 56 cm x 3 cm = “dimensions” = extensive property
68 cm x 56 cm x 3 cm = “volume” = extensive property
What is the Styrofoam’s volume? Calculate it!
68 cm x 56 cm x 3 cm = 11,424 cm3
white = intensive property
“Styrofoam” = polystyrene = (C8H8)n = intensive property
173 grams = extensive property
density = mass / volume = intensive property
Calculate it! density = 173 g / 11,424 cm3 = g/cm3

16. Chemistry
Tuesday 8/29/2017
HOMEWORK: 2.2 notes, Practice Problems (self-check!)
WARM-UP: What should happen when you put gasoline and water in the same bottle and shake it?
STAMPS: 2.1 section assessment (again, p4), 2.2 notes (all other periods)
Done w/warm-up? Get started on the homework.

17. Chemistry Wednesday 8/30/2017 HOMEWORK: 2.2 Section Assessment
WARM-UP: How does a filter separate components of a mixture? How does distillation do it?
STAMPS: 2.2 notes, practice problems (#’s 9 & 10)
(All periods can get these stamps today. I’m not picky today.)
Done w/warm-up? Get started on the homework.

18. Chemistry Thursday 8/31/2017 HOMEWORK: 2.3 notes, practice problems
WARM-UP: What phase changes take place in a distillation apparatus?
STAMPS: 2.2 section assessment (#’s 11-17)

19. Chemistry Friday 9/1/2017 HOMEWORK: 2.3 section assessment
WARM-UP: Compare the properties of ethyl alcohol (CH3CH2OH) to the properties of carbon, hydrogen, and oxygen.
STAMPS: 2.3 notes, practice problems (#’s 18 & 19)
Done w/warm-up? Get started on the homework.

21. WARM-UP: Compare the properties of ethyl alcohol (CH3CH2OH) to the properties of carbon, hydrogen, and oxygen.
Ethyl alcohol (CH3CH2OH):
volatile, flammable, colorless liquid,
kills living cells (bacteria AND your cells, too!),
sharp smell, carcinogenic, intoxicating
Carbon (C):
black, soft, solid (unless it’s a diamond!),
flammable but otherwise not very reactive,
Hydrogen (H2):
colorless, odorless gas; flammable; less dense than air
Oxygen (O2):
colorless, odorless gas; supports flames & burning of food
in living things
