Mr. Friedrich “Freed rik" Chemistry Class Introduction
If you get behind , You may NEVER Catch up !
My #1 Goal Help students develop the skill of critical thinking.
My #1 Goal CRITICAL thinking is the process of analyzing and applying what you already know as a guide to action.
My #1 Goal Critical thinking attempts to intellectually figure something out.
My Worst Fault Running out of time!
SparkPlease read the scientific data handout and answer the questions that follow.
The Picture of Good Health! Cat Beverage
Read the TV article Highlight/underline any words that you don’t know and can’t figure out using the context. Describe the experimental design… What is the main idea of the article? What evidence supports the main idea? Identify the kind of data used in the research. Do you agree with the author’s conclusion about the research?
Freakonomics Which are more dangerous for kids, swimming pools or gun? Does a child’s name affect how successful they will be as adults? Do the police really lower crime rates? Does the death penalty lower the murder rate? Do parents matter?

Communication Everything a scientist writes is an argument… Scientists want to convince people of their ideas based on evidence! ??????????????????????? There are many ways to communicate in science! Memos, emails, blogs, paragraphs, essays, research articles/reports, books
Spark Find your new seat, then… Please read the first nine chemistry sub-disciplines handout, develop questions, and consider which sub-discipline you feel is most interesting or most important.
What is Chemistry?
The study of the properties of materials and the changes that materials undergo.
You know the active ingredient in beer is C2H5OH.
Instead of saying ozone, you say O3.
You refer to the smell of nail polish remover as an acetone smell.
You ask for acetaminophen instead of Tylenol.
Even Better: You ask for acetylsalicylic acid Instead of aspirin
You know the hazards of mixing trinitrotoluene and tetrahydrocannabinol
That’s TNT (dynamite) and THC (marijuana)
When you hear the word MOLE, you think of the number 6.02 X 1023 instead of a small furry animal.
You wash your hands BEFORE you go to the bathroom.
PPE Personal Protective Equipment
Safety glasses should ALWAYS be worn during a lab.
NO! NO! NO! Long hair should be tied back.
Lab Safety
NO! NO! NO! Bulky and loose clothing Are dangerous in the lab.
Flammable materials must be kept away from lab burners.
Problem Based LearningA critical thinking task • Always ask, “What is the quality of the evidence supporting the claim?” • Good Science vs Bad Science vs Pseudoscience • Health care is a multi-billion dollar industry full of deception and fraud • Alternative therapies: homeopathy, iridology, therapeutic touch, reflexology, acupuncture and acupressure
