Week 1

3. What is lead? What is lead in?4. Making a template5. Figuring out which bags we will use4. Practicing using the template

Week 3“ownership” requires weekly activities

“ethics” requires education

3. Slide show on public health4. Slide show also discusses the analytical procedure5. Active materials - crossword puzzle - word search

Loyola Student Designed Curriculum

Across3. the system of pipes and other apparatus for conveying water,

liquid wastes, etc., as in a building4. the fluid that circulates and carries oxygen throughout the human

body5. being placed at risk8 the quality of degree of being toxic or harmful to plants or animal

life9. the introduction of harmful substances or products into the

environment10. a mixture of pigment and liquid12. food, eating healthy14. a pain located in the head15. the age group affected most by lead poisoning17. President on the $20 bill18. a transparent, odorless, tasteless liquid, a compound of hydrogen

and oxygen, H20, that constitutes rain, oceans, lakes, rivers, etc.19. . to take ill through eating

Down2. a heavy, comparatively soft, malleable, bluish‑gray metal. A

toxic metal, that has been widely used in paints, plumbing and fixtures, and in some water supply service lines

3. composer thought to have had lead poisoning5. the portion of the earth's surface consisting of dirt6. the air, water, minerals, organisms, and all other external factors

surrounding and affecting a given organism at any time7. dry particle of earth10. a table illustrating the periodic system, in which the chemical

elements are shown in related groups11. . the process of preparing the samples by breaking down the baby

wipes into a substance suitable testing13. a silver‑white divalent metal found in limestone, chalk, milk16. the science that deals with the composition and properties of

substances and various elementary forms of matter

Week 4Graphing the data

In practice we found that students were not prepared to makeHistograms. We intend to create one session around graphingCandy.

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?
