Lead Poisoning Preventiongoblet.jpg (2311 bytes)

"Lead's discovery dates back to 3500 BC. Lead artifacts have been found throughout the ancient world, and some researchers have suggested that lead poisoning was a major factor in the downfall of the Roman Empire.

Well-to-do Romans painted their walls a rich Pompeian red, which owed its color to a salt of lead or mercury. Lead was used for water pipes, cups, toys, statues, cosmetics, coffins, and roofs, but the most significant source may have been the wine of the wealthy class.

Sister Columba Gilfillan proposed a theory for Roman decay in 1965 that involved "poisons esteemed as delicious by the ancient well-to-do." Spoilage was a problem in ancient Rome, and vintners discovered that wine tasted better and lasted longer if it was mixed with a concentrated grape syrup called sapa. The best sapa was boiled in lead pots, allowing lead to leach into the syrup. When sapa was mixed with wine, it sweetened it and also poisoned the microorganisms that cause fermentation and souring. Sapa was also used in fruit and honey drinks, and as a food preservative.

Josef Eisinger estimated that a Roman consuming a liter of wine a day would ingest about 20 mg of lead per day, which he said was more than enough to produce chronic lead poisoning."

Teacher's Guide

Lesson Objectives:
                - to recognize the dangers associated with lead, the sources of lead and the prevention and treatment of lead poisoning
                - to develop skills in working together successfully with others
                - to develop community problem solving strategies
                - to develop skills in thinking logically
                - to use English to talk about solving problems
                - to help students develop a textual visual map for solving problems

Multiple Intelligences Developed in this Lesson:
                - Linguistic
                - Logical/Mathematical
                - Interpersonal
                - Intrapersonal
                - Visual/Spatial

Procedure:
- Ask the students what they know about lead poisoning.

- Distribute a Lead Poisoning Prevention lesson packet to each student. A lesson packet includes a title page, a content outline, a group problem solving activity* and a student feedback form. Have the students complete the left side of the feedback form.

- Read the quote on the title page to the students.

- Have the students take turns reading the outline. Using the glossary, define any unfamiliar vocabulary for the students. Answer any questions the students may have.

- Direct the students to turn to the "Why do I have reservations?" page in their packets. Read the problem aloud to the students. Read aloud the parts of the chart to the students. Divide students into groups of 3, 4 or 5 depending on class size. Direct each group to appoint a reader, a secretary and a spokesperson. Once each group has completed its chart, have the groups share their results with the rest of the class. Give the students the option of acting out the problem.

- Direct the students to complete the right side of the feedback form. Collect the forms. Using the facts on these forms for dictation would be an excellent additional use of these forms.

*The group problem solving lessons in this manual have a multiple intelligence focus and are adapted from a unit on social responsibility in A Guidebook for Applying MI Theory in the Second Language Classroom by Maryann Christison, Ph.D., Burlingame, CA: Alta Book Center Publishers, 1999.
