Intersection 1: Intro to Gateway 9/5/06 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> http://www.m-w.com/cgi-bin/dictionary?book=Dictionary&va=chemistry To be a scientist or chemist… • What do you think of when you think of chemists? 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… Chemistry…. • What do you expect from this course? •What do you want to be able to do? Course Goals To Be Chemists: 1) 2) 3) 4) 5) Chemistry concepts Analysis & Connections Creativity Problem Solving Communication and team work 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 Why Gateway? • Is there a right way to do science? purpose hypothesis results conclusion procedure discussion • Is there a right way to teach chemistry?
