11. Tailpipe Emissions: A Study in Cause/Effect Relationships (2001-2002 SyRIS Module)
Tim Frank (South Mountain)

12. The Power of the Exponent (2001-2002 SyRIS Module)
Pushpa Ramakrishna (Chandler-Gilbert)
To better comprehend the complex concept of exponents, a case study is set up with a professor dying from food poisoning. Biology students study the exponential growth of bacteria; math students and physics students use Newton's Law of Cooling to explore the concept of exponents. Math students also explore this concept through application problems such as a rumor mill.

13. The Problem with Pesticides (2000-2001 SyRIS Module)
James Giles (Mesa)
Each of the activities in this module is directed at studying a pesticide from the perspective of a different discipline. Areas of particular emphasis include biology, geology, agriculture, and chemistry. The lab activities are designed to encourage students to develop and test their own hypotheses in an active learning setting.

14. The Science of Survival: Temperature and Biological Adaptation (2001-2002 SyRIS Module)
Patricia Ashby (Scottsdale)
In this module, students begin to understand the factors that allow organisms to thrive in various climates by addressing such topics as cooling rate versus surface area, water management by plants and insects, and metabolism rates. In small groups, students examine the principles of heat transfer, observe the mathematical relationships between size and cooling rate, and investigate the chemical composition of surface layers exposed to temperature fluctuations. In addition to the emphasis on temperature, the module also addresses how size, metabolism, and surface properties influence an organism's water management. A poster presentation concludes the module.

15. Ultraviolet Radiation: From Sun to Skin (2000-2001 SyRIS Module)
Suzanne Kelly (Scottsdale)
This module presents central concepts of radiation: its origins, characteristics, and interaction with the earth's atmosphere and living organisms. The laboratory component includes experiments to measure light intensity with application of the Inverse Square Law and to examine the effects of ultraviolet light on cultures of pigmented yeast that have been covered with and without sunscreen.

16. Water Purification (2000-2001 SyRIS Module)
Ann Scarbrough (South Mountain)
This module introduces geological, physical, and chemical concepts for separating contaminating materials and substances in water. It uses the method of inquiry at the introductory, fundamental, or preparatory level and is intended for non-science majors in introductory science courses.
