Intersection 1: Intro to Gateway

1. Intersection 1: Intro to Gateway 9/5/06 Reading: 1.1-1.2 p 2-5

3. 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> http://www.m-w.com/cgi-bin/dictionary?book=Dictionary&va=chemistry

4. To be a scientist or chemist… • What do you think of when you think of chemists?

5. Chemists Discuss, 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…

6. Chemistry…. • What do you expect from this course? • What do you want to be able to do?

7. Course Goals To Be Chemists: • Chemistry concepts  • Analysis & Connections 3) Creativity 4) Problem Solving 5) Communication and team work 

8. Range of Chemistry Questions… Knowledge: list, define, identify, recall Comprehension: compare, contrast, group, order, discuss Application: 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

9. Why Gateway? • Is there a right way to do science? • Is there a right way to teach chemistry? hypothesis results conclusion purpose procedure discussion

10. Model of the Scientific Method

12. Use of time

13. Course components • Intersection: Concept questions, lecture, problem solving • Studio: discussion, activities, models, presentation, peer evaluation, models (learning and applying) problem solving, case studies, experimentation

15. Integrated Lecture and Lab • 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 • Could I teach you how to drive a car without getting behind the wheel?

16. 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) http://main.uab.edu/show.asp?durki=1479 http://www.doctorsecrets.com/secrets-in-medicine/medical-school.html

28. 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?

29. Question 5 • The circle on the left shows a magnified view of a very small portion of liquid water in a closed container. What would the magnified view on the right show after the water has all evaporated?

31. Define the following: • Fact • Law • Theory • Hypothesis • Model

32. According to the National Academy of Science, a Hypothesis is: A testable statement about the natural world that can be used to build more complex inferences and explanations These definitions (and an excellent explanation of the scientific method) can be found at: http://www.nap.edu/readingroom/books/evolution98/
