## Exploring Solutions Ddilutions

C.10.D Use molarity to calculate the dilutions of solutions

Use your Student Progress Tracker to decide which level to start on. Complete at least 1 DIY for that level, then get the quiz from Mrs. Whitfield. Complete the quiz. Then proceed to the next level. You must complete Level 3 ("Meeting Expectation") but you may also complete Level 4 ("Exceeding Expectations") if you would like. Please jot down on your student tracker what you did for the DIY (and if you requested any workshops). The quizzes for Levels 1-3 will be averaged for the one daily grade for C.10.D; if you "placed out" of Level 1 or Level 2, you do not need to take those quizzes. If you choose to complete Level 4, the points earned on the worksheet will count as bonus points for this daily grade.

1. Initiating Progress Students correctly identify data used to calculate dilutions of solutions. DIY Read Ch. 9 Section 2, page 277 (ebook p. 289). Preparing a Solution. Assess: Complete Level 1 Progress Check.

2. Approaching Expectation Students use molarity to calculate the dilutions of solutions given units of molarity. DIY Complete the Solution Dilution Worksheet & self-check. Assess: Complete Level 2 Progress Check.

3. Meeting Expectation Students use molarity to calculate the dilutions of solutions given units of molarity. DIY Complete the 10-Square Worksheet, calculating molarity and dilutions (on back of C.10.C Level 2 DIY). Assess: Complete Level 3 Progress Check.

4. Exceeding Expectation Students use molarity to calculate the dilutions of solutions given units of molarity and ppm or other units. DIY/Assess combined Read and complete "Molality and Freezing Point Depression" worksheet.
