Week 1
1. What is lead? What is lead in?
2. Making a template
3. Figuring out which bags we will use
4. Practicing using the template
Week 3
“ownership” requires weekly activities
“ethics” requires education

Explicit Ethics Lab
How do we know?
How do we have confidence?
What do we owe our collaborators?
What do we owe science? Is it the same?
How do we engage in scientific dispute?
Reading of a series of articles exchanged
between Needlemen and his detractors
What ethical reasoning systems do we apply to
explain the behavior of Needleman and his
detractors?
