Intersection 1: Intro to Gateway9/5/06

Reading: 1.1-1.2 p 2-5

What is Chemistry?

1 : a science that deals with the composition, structure, and properties of substances and with the transformations that they undergo

2 a : the composition and chemical properties of a substance <the chemistry of iron> b : chemical processes and phenomena (as of an organism) <blood chemistry>

3 : a strong mutual attraction, attachment, or sympathy <they have a special chemistry>

To be a scientist or chemist…

• What do you think of when you think of chemists?

ChemistsDiscuss, model, explain, present, question,

experiment, read, calculate, form ideas, propose hypotheses, argue, make connections, conclude, think, learn, write, observe, teach, collaborate, synthesize, analyze, collect data, test, experiment, have fun

Better living through chemistry…

Chemistry….

• What do you expect from this course?

•What do you want to be able to do?

Course Goals

To Be Chemists:1) Chemistry concepts  2) Analysis & Connections3) Creativity4) Problem Solving 5) Communication and team work 

Range of Chemistry Questions…

Knowledge: list, define, identify, recall

Comprehension: compare, contrast, group, order, discussApplication: apply, calculate, solve

Analysis: analyze, separate, explain, connect, classify

Synthesis: combine, integrate, modify, rearrange, substitute, plan, create, design, invent, what if?, compose, formulate

Evaluation: assess, decide, grade, test, measure, recommend, convince, judge, explain, discriminate, support, conclude

Why Gateway?

• Is there a right way to do science?

• Is there a right way to teach chemistry?

Integrated Lecture and Lab

• Could I teach you how to drive a car without getting behind the wheel?

•Make connections

•A scientist isn’t a scientist without doing things that scientists do

•Chemists don’t separate problem solving or concepts from experimentation; they actually work in a studio like environment

Why teach like this?• Average attention span is 20 minutes• Cooperative learning has been shown to

help students increase learning• People learn in a variety of ways• Prepare you for future challenges that will

involve chemistry (be it classes or not)

a) What is the source of the black film on the rod? b) Is there a chemical change or a physical change in

the candle as it burns? c) Give an example of a chemical change: d) Give an example of a physical change

Question 4

• There are two identical steel beams. One is placed on each side of a balance. A flame is used to heat one of the steel beams. Does the balance move? If so, how and why?

Define the following:

• Fact• Law• Theory• Hypothesis• Model

A testable statement about the natural world that can be used to build more complex inferences and explanations

According to the National Academy of Science, a Hypothesis is:

These definitions (and an excellent explanation of the scientific method) can be found at:

http://www.nap.edu/readingroom/books/evolution98/

In science, an observation that has been repeatedly confirmed.

According to the National Academy of Science, a Fact is:
