In this activity, students analyze a 2011 article by physicist Dr. Richard Muller addressing the climate change skeptic's claim that the scientific data used to support global warming is poor or unreliable. He headed a two-year study where his... (View More) research team examined sources of data independently of climate scientists, and concluded that despite the imperfections in the available data sets, scientists have managed to avoid bias in data collection and correction. A student worksheet provides questions to guide the investigation. This activity is supported by a textbook chapter, What is Global Warming?, part of the unit, Climate Change, in Global Systems Science (GSS), an interdisciplinary course for high school students that emphasizes how scientists from a wide variety of fields work together to understand significant problems of global impact.

This article describes an approach designed to decrease math anxiety and teach students about the use of mathematical symbols simplifying radicals. A deck of cards is used in a demonstration, and a problem set using real life examples to master the... (View More) use of radicals is included. This resource is from PUMAS - Practical Uses of Math and Science - a collection of brief examples created by scientists and engineers showing how math and science topics taught in K-12 classes have real world applications.
