7th Science - Chapter 5 Test today.  No new assignments.

7th Religion - Discussion Questions over Matthew 2 are due Thursday (11/15):

1. Who did God speak to in a dream in Matthew 2?  Do you think that God still speaks to people in dreams?
2. Jesus’ 3 fold office is as prophet, priest, and king.  Which do you see Jesus as most; which title fits Jesus the best, in your opinion?
3. It was not fair that so many baby boys died when Herod got jealous.  Why do you think God allows such terrible things to happen (i.e. the Holocaust, 9/11, etc.)?

11/12

8th Science - We read page 104 and made a colloid in class - butter.  A "open-notes" test over chapter 4 will happen on Thursday (11/15) and students are allowed to use any hand-written notes that have been written in their science notebooks.  Answers to the chapter review are also online, if students would like to use them to study.

7th Religion - Practice quiz over Matthew chapter 2.  Discussion questions will be assigned tomorrow.

8th Science - Chapter 4 Review

1. compound

   2.  solubility

   3.  suspension

   4.  element

   5.  nonmetal

   6.  solute

   7.  C

   8.  B

   9.  C

10.  B

11.  C

12.  A

13.  C

14.  A

15.  Elements cannot be separated into simpler substances, but compounds can be separated by chemical means.

16.  Nail polish is the solute, and acetone is the solvent.

17.  50 g/200 mL = 0.25 g/mL

18.  150 mL ´ 0.6 g/mL = 90 g

19.  

20.  Carbonated beverages should be stored in a refrigerator. Gases are more soluble at lower temperatures, so more gas will stay dissolved in the beverage if it is kept cold.

21.  The powder is a compound. The change in color and the formation of a gas imply that a chemical change took place. Compounds can be broken down by chemical changes.

22.  The exact concentration tells you exactly how much solute is dissolved in the solvent. Concentrated and dilute are descriptive terms that do not tell you the amount of solute.

23.  Sample answer: Pass the mixture through a screen that allows the salt and pepper to pass through but traps the pebbles. Mix the salt and pepper with water to dissolve the salt. Filter the mixture to trap the pepper. Evaporate the water to recover the salt.

24.  (Teacher’s Note: The graph should have “dissolved solute” on the y-axis and temperature on the x-axis. The curve will decrease from left to right.) You should decrease the temperature to increase the solubility. As the temperature decreases, more solute can dissolve.

25.  68 g

26.  Because the solubility increases as the temperature decreases, the solute is most likely a gas.
