​

3rd and 6th will complete the Bunsen Burner/ steel wool lab.  The lab page will be due Tuesday with a brief 6 question (multiple choice) quiz over the lab. 

 

There will also be a handout over spectrophotometry (quantitative measurement of emitted wavelengths of the spectra) and chloride salts.  We will be reproducing Robert Bunsen's experiment where he burned various elements and compounds to see what colors were emitted and quantify their wavelengths.  This is how he discovered cesium and rubidium. On Tuesday, we will burn 8 different chloride salts and observe their characteristic colors.  We will attempt to quantify the wavelength of each color emitted. You will need to make sure you have read this informational packet and have some rudimentary understanding of the electromagnetic spectrum. (I am sorry, but I do not have a pdf for this.)

​

2nd, 4th and 7th will have the steel wool lab due with the 6 question quiz over the lab.  These hours will also get the informational packet described above in preparation for Tuesday's lab.

Tuesday 10/8/19

​

3rd and 6th will have the steel wool lab page due with a 6 question, multiple choice lab quiz.

​

All classes will complete the spectrophotometry flame test lab.  Lab sheet will be due on Wednesday with a 10 point T/F quiz over the lab.

Wednesday 10/9/19

​

Lab sheets will be due with a 10 point T/F quiz.

​

We will discuss the Mole Day festivities where we pay homage to the Mole, a unit of measure in chemistry.  The mole is often called Avogadro's number because Count Amedeo Avogadro is credited for determining this value in the early 1800's.  Since atoms are very, very small, we cannot count them individually.  We group a large group of atoms together and count the groups of atoms.  We group 6.02 x 10^23 atoms or particles together and call it a mole.  This is similar to counting individual eggs versus 1 dozen of eggs. A mole is a HUGE number.  If a person started counting today, they could never reach that number in their lifetime.

​

Here is a very nice, short article on the mole.

​

We will be celebrating mole day on Monday, October 21st.  We complete a mole cartoon and it will be due on that day.  The "Moletoon" will be a hand drawn cartoon that includes a mole (the animal) and a pun.  I will show you lots of examples so you get the idea.  Here is the rubric below.

We will also do a lab involving the Bunsen burner on Moleday.  We will toast 'marshmolos' and make 'smoles'.  See what I did there?  More to come on that.  Stay tuned.

Thursday 10/10/19

​

We will be taking the quarterly assessment test today.  This will cover only Topic 1: Lessons 1, 2 and 3.  This will use a  SCANTRON type of answer document.  This test will take the entire class period.  You will need to bring something to occupy yourself after the test is completed.  There will be NO TALKING, VISITING or GENERAL DISRUPTION allowed.  I will have you removed if you find this task of remaining quiet after you have completed the test too difficult.  This will be for a grade on this quarter.

​

Friday 10/11/19

​

This is only a 1/2 day of attendance.  Class periods will run about 20 minutes each with dismissal at 11:00.  

​

Guided Reading for Topic 1: Lesson 4 "Types of Bonds" guided reading is for homework.  It will be due on Tuesday.  Here is the  worksheet for you to download.
