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.

VIDEO: THE BUNSEN BURNER

Mr. Hatfield has made a video to demonstrate the correct way to use the Bunsen burner.  Make sure you review this before you come to class on Tuesday, as we will be using the Bunsen burners in Mr. Diaz's classroom to perform the flame test lab.
