Hazardous Materials Investigations: The Barrel Mystery
What happens when unidentified, hazardous wastes are left abandoned? This module focuses on the physical and chemical properties of substances. Students explore the contents of a barrel of simulated hazardous waste as they learn to physically separate, test, and identify substances in a mixture. They investigate different types of chemical hazards and describe hazardous substances in the home. Students evaluate the trade-offs involved in the transportation of hazardous materials as they create a plan for transporting large amounts of hazardous waste from one area to another. Students are assessed on their ability to analyze data.
Each module includes a Teacher’s Guide containing reproducible student pages and a kit containing the equipment required to conduct the activities with five classes of 32 students. The Teacher’s Guide provides specific strategies to facilitate and assess student learning.
Shown below is the table of contents for the teacher’s guide, which contains reproducible student pages.
