POWER POINT: THE MOLE

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 Tuesday the 17th, in which students were given examples of and practiced solving problems in which students do calculations with moles. 

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

STUDY HALL will occur Tuesday 10/24-Thursday 10/26 during lunch next week.     Students who have been assigned STUDY HALL must attend, or they will be treated as defiant.

Unit 3 began on Monday the 16th.  A new syllabus for that unit will be made available on Wednesday the 18th.

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 Wednesday.   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:

POWER POINT: ELECTRON CONFIGURATION

Students, here is the Power Point for the second group of notes for Unit 2, on electron configuration, orbitals, models of the atom, and rules for electrons:



Students should use this along with the previous section of Notes to complete the Study Guide for next Friday's test (10/13), and along the way make sure that everything in the Study Guide does, in fact, appear in the notes in their Composition Book.
