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

Integrated Lecture and Lab

• Make connections
• A scientist isnt a scientist without doing
  things that scientists do
• Chemists dont 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?

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)
