SYLLABUS, UNIT 3

Students, here is the new syllabus for Unit 3:



Please note that this unit began more than a week ago. We spent most of last week simply rehearsing (MANY times!) how to calculate the molar mass of a compound, and how to convert from moles to grams, or from moles to particles.  

Your first homework assignment on moles and stoichiometry was given in class on Friday!  This is challenging material, you need to do it right away.  Don't FALL BEHIND.


VIDEO: THE MOLE

Students:  here is Paul Anderson's video, as shown in class, explaining the concept of the mole with helpful illustrations:




Student should use this video to complete a worksheet given in class, which is also available online HERE.

POWER POINT: CHEMICAL QUANTITIES AND MOLES

Students, you can find the latest Power Point Notes on Chemical Quantities and Moles HERE:




This comes at the end of four days of instruction, beginning on Friday the 14th, in which students were given examples of and practiced solving problems in which students do calculations with moles. 

At the end of today's lesson, they were given a Homework assignment, "Calculations With Moles." That item is available HERE.

STUDY HALL will occur the next two weeks at lunch (Tuesday and Thursday), and after-school on Wednesday.   Students who have been assigned STUDY HALL must attend, or they will be treated as defiant.

Unit 3 began on Thursday the 13th.  A new syllabus for that unit will be made available next week.

Flame Test Lab

If students were absent on the day we were guests in Mr. Diaz's classroom, they did not get to see the actual lab where we performed a 'flame test' on various ionic compounds.   

Here is a video that shows much the same sort of observations students made on Tuesday.   Unfortunately, we do not have Bunsen burners in my classroom, and so it is not practical to 'make up' the lab.   Watch the video, students, and compare it with observations that students who attended were able to make in order to understand the material:
