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 article discusses the differences between ozone in the stratosphere and troposphere, and how NASA is measuring ozone using a spectrometer on-board the Aura satellite. The article includes an activity: building a spectroscope using a DVD cover... (View More) and inexpensive materials. (View Less)
The front of this poster is a cartoon profile of the atmosphere, showing the "good and bad" roles of ozone in the stratosphere, high troposphere, mid-troposphere, and surface. On the back is an article for students, beginning with an explanation of... (View More) ozone's roles, and an introduction to spectroscopy. Also includes detailed instructions for building a classroom spectroscope using a CD or a DVD as a diffraction grating. See related resources to download a PDF file that is a pattern for making the spectroscope body out of construction paper. (View Less)
In this data analysis activity, students investigate the relationship between between surface temperature, tropospheric ozone, and air quality. Step-by-step instructions for use of the MY NASA DATA Live Access Server (LAS) guide students through... (View More) selecting a data set, importing the data into a spreadsheet, creating graphs, and analyzing data plots. The lesson provides detailed procedures, related links and sample graphs, follow-up questions, extensions, and teacher notes. Designed for student use, MY NASA DATA LAS samples micro datasets from large scientific data archives, and provides structured investigations engaging students in exploration of real data to answer real world questions.

This is a lesson where learners explore how the creation and destruction of ozone protects us from ultraviolet radiation (UV). Learners will kinesthetically model the depletion of ozone caused by chlorofluorocarbon (CFC) molecules; use ultraviolet... (View More) beads to "discover" ultraviolet radiation, and discuss the effects of ultraviolet radiation on humans; model and create a poster of how ozone is created and destroyed and how this process helps to protect us from ultraviolet radiation; and read about the ozone layer and model the depletion of ozone due to CFC molecules. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes, prerequisite concepts, common misconceptions, student journal and reading. This is the sixth lesson in the Astro-Venture Atmospheric Science Training Unit. The purpose of the unit is to increase students' awareness of and interest in astrobiology and the many career opportunities that utilize science, math and technology skills. The lessons are designed for educators to use in conjunction with the Astro-Venture multimedia modules. (View Less)
