This ChemMatters article provides a history of the study of ozone, a description of an experimental simulation called "The World Avoided," a brief introduction to the chemistry of ozone, an explanation of how ozone is measured, and the difference... (View More) between "good" ozone in the stratosphere vs "bad" ozone in the troposhere. ChemMatters is an educational magazine published by the American Chemical Society. (View Less)
This ChemMatters article provides a brief background on smog, then examines the causes of it, efforts to reduce it, and methods used to measure it. ChemMatters is an educational magazine for high school students.
This problem-based learning module places learners in the role of researchers analyzing carbon monoxide's environmental impact. Both vehicle emissions and biomass burning are cited as events producing carbon monoxide that impact the environment.... (View More) Instructions for accessing NASA data from four different sources are provided along with suggested resources and investigations for classroom use. 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.

In this activity, users examine satellite images from NASA's Total Ozone Mapping Spectrometer (TOMS) that show how much ozone is in the atmosphere over the Southern Hemisphere. They interpret the images to identify ozone thinning that develops over... (View More) this region each summer, and compare its size from year to year. Using freely-available image analysis software, ImageJ, users quantify the area of the Antarctic ozone hole each October from 1996 to 2004. Finally, they bring their measurements into a spreadsheet program and create a graph to document changes in the size of the ozone hole. This chapter is part of the Earth Exploration Toolbook, which provides teachers and/or students with direct practice for using scientific tools to analyze Earth science data. Students should begin on the Case Study page. (View Less)
This activity is about the role of plants as carbon sinks. Using atom signs made of construction paper, a blanket and other materials, learners will visualize the role of plants in storing carbon and discuss what may lead to its release. This the... (View More) second of three activities in "The Carbon Cycle and its Role in Climate Change," which is part of Climate Change, Wildlife and Wildlands: A Toolkit for Formal and Informal Educators. (View Less)
This activity is about how fossil fuels release carbon. Learners will use toys, sand and other materials to simulate a city, considering the formation of fossil fuels and how burning these releases carbon and produces warming. As part of the... (View More) discussion, they will review the respiration equation. They will then create a mural illustrating the path of the carbon from dead forest, to fossil fuel, to mine, to power plants, to homes and cars, and finally to the air. This the third of three activities in "The Carbon Cycle and its Role in Climate Change," which is part of Climate Change, Wildlife and Wildlands: A Toolkit for Formal and Informal Educators.

In this problem-based learning activity, learners investigate impact of sulfur dioxide on the environment. Sulfur dioxide comes from both human activities and natural sources. Burning coal and other fossil fuels is the largest source of sulfur... (View More) dioxide from human activities. Students have a choice of analyzing the impact of volcanoes’ emissions of sulfur dioxide on the environment; they can also investigate the idea of injecting sulfates into the atmosphere to counteract global warming. Instructions to access NASA data are provided along with 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.

This activity is about the carbon cycle. Using construction paper and signs, learners will simulate chemical bonds and the energy exchanges that take place during the carbon cycle. They will then respond to questions about the processes of... (View More) photosynthesis and respiration. This the first of three activities in "The Carbon Cycle and its Role in Climate Change," which is part of Climate Change, Wildlife and Wildlands: A Toolkit for Formal and Informal Educators.

In this problem set, learners will answer a series of questions about the complex molecule, Propanal. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change.
In this activity, students devise ways to demonstrate that energy can change from one form to another in accord with the law of conservation of energy. Small appliances, toys, marbles, vinegar and baking soda, simple electrical supplies available... (View More) from a hardware store, and thermometers are needed to complete this activity. A student worksheet and an assessment rubric are included with the resource. The investigation supports material presented in chapter 1, "What is energy?” in the textbook Energy flow, part of Global System 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.
