In this problem-based learning unit, learners examine the causes and impacts of dust transported through the atmosphere. An estimated two billion tons of dust is emitted by the Earth annually. Scientists are becoming increasingly interested in the role dust plays in climate change. Students are asked to conduct an Earth system analysis of dust's impact on weather and climate. Links to NASA remote-sensing data is provided along with detailed instructions, and additional resources and activities. This module was developed to be used in the Earth System Science Education Alliance (ESSEA) courses for middle and high school teachers and is also available to teachers to adapt for general classroom use.
