Procedures:•NO CELL PHONES AT ANY TIME FOR ANY REASON!!!•Be in your seat BEFORE the bell rings.•Bookbags on the floor, NOT on the desk.•Water in screw-top bottles allowed–all other food and beverages are prohibited (safety issue).•You may only use your personal bathroom passes to go to the restroom at the end of the 300 Hall. If you are gone longer than 15 minutes, you will be written up for skipping class.•Check the class website frequently for homework and classwork assignments and for printouts of the notes.•If you do not have the notes already printed out and in front of you, you MUST take notes during note time.

Tests (35%):•Tests are announced 1 week ahead of time so students that are absent the day before the test will be expected to take the test upon their return.•Maximum score on a test retake is 70%•I accept test corrections (max score of 80%) provided the test correction guidelines are followed.

Quizzes (20%): There are no quiz retakes

Homework (10%): •Most will be graded for completion only•Stamp sheets are collected on Fridays (usually) and are the ONLY record of the homework that you’ve done•No late homework will be accepted

Labs (25%):•Work with your assigned lab partners and in your assigned lab groups.•Students engaged in off-task, disruptive or dangerous behaviors during lab will receive a zero for the lab.

Failure to follow lab rules will result in the cessation of ALL LAB activities for the entire class

so POLICE YOURSELVES!! Can we talk about science

now??

Chemistry is the study of matter and the changes it

undergoes.

So…what is chemistry all about?

While reading a textbook of chemistry I came upon the

statement, "nitric acid acts upon copper." I was getting tired of

reading such absurd stuff and I was determined to see what

this meant. Copper was more or less familiar to me, for copper

cents were then in use. I had seen a bottle marked nitric acid

on a table in the doctor's office where I was then "doing time." I

did not know its peculiarities, but the spirit of adventure was

upon me. Having nitric acid and copper, I had only to learn

what the words "act upon" meant. The statement "nitric acid

acts upon copper" would be more than mere words.

Obj. 1.01

All was still. In the interest of knowledge I was even willing to

sacrifice one of the few copper cents then in my possession. I

put one of them on the table, opened the bottle marked nitric

acid, poured some of the liquid on the copper and prepared to

make an observation. But what was this wonderful thing which

I beheld? The cent was already changed and it was no small

change either. A green-blue liquid foamed and fumed over the

cent and over the table. The air in the neighborhood of the

performance became colored dark red. A great colored cloud

arose. This was disagreeable and suffocating. How should I

stop this?

Obj. 1.01

I tried to get rid of the objectionable mess by picking it up and

throwing it out of the window. I learned another fact. Nitric acid

not only acts upon copper, but it acts upon fingers. The pain

led to another unpremeditated experiment. I drew my fingers

across my trousers and another fact was discovered. Nitric

acid acts upon trousers. Taking everything into consideration,

that was the most impressive experiment and relatively

probably the most costly experiment I have ever performed...

It was a revelation to me. It resulted in a desire on my part to

learn more about that remarkable kind of action. Plainly, the

only way to learn about it was to see its results, to experiment,

to work in a laboratory.

Super Science Safety SystemFailure to follow safety rules will result in a zero for the lab!!!

• Report ALL accidents to the teacher IMMEDIATELY.• Follow all written and verbal instructions carefully.• No unauthorized experiments.• No horseplay!!!• Do not enter lab storage areas or open storage cabinets.• Keep hair and clothing out of the way – tie back long hair, roll up long

sleeves, remove ties, coats and bulky sweaters.• Never taste or touch chemicals unless specifically instructed to do so.• Waft fumes to note odors.• Wear goggles whenever a flame is present, when handling chemicals and

when working with potential projectiles.• Never handle broken glass with your bare hands.• Do not discard any solids in the lab sinks.• Wash hands thoroughly with soap and water at the conclusion of each lab.• USE COMMON SENSE!
