· Ready, Aim, Fire

• analogy of firing gun
• grading policy handout
• Target
• hand out texts
• SI prefixes (p. 35)
• kilo 10³ k
• deci 10^-1 d
• centi 10^-2 c
• milli 10^-3 m
• micro 10^-6 m
• nano 10^-9 n
• pico 10^-12 p

• memorize 7 prefixes

Wednesday 6 September 2006

• What good is chemistry?
• scientist and artist
• review SI prefixes

• define algorithm

Algorithm

A set of rules or steps used to guide one through solving a problem.

• conversion factors
• all have a numeric value of one
• 12 apples = one dozen apples
• You already know how to convert 24 apples to dozens, so we'll analyze the procedure to get the algorithm
• e.g.: 23 ft to m; 1500 g to kg, dg, and mg
• 1 ft = 0.305 m
• "Group Problem Solving" notes

Group Problem Solving

types:

1) cognition problem

-solution will have a specific answer

2) coordination problem

-organizing the behavior of people in a group

3) cooperation problem

-getting people to work together

requirements:

1) diversity

2) independence

3) decentralization

Each person in a lab group should think as independently as possible.

Thursday 7 September 2006

• review group problem solving
• wayward ant
• "quenched disorder" of Complexity Theory
• record lab data so it makes sense to another person

Each lab data should have:

1) a label

2) the number with proper significant digits

3) proper unit(s)

• "Using the Balance" lab
• get class average for lab (P2, P7)

Friday 8 September 2006

• get class average for lab (P1)
• define "percent discrepancy"
• write up "Using the Balance" lab
• discuss the conclusion
