This activity demonstrates optical properties of water: that different constituents in water affect the transmission, absorption, and scattering of different colors in the visible light spectrum. Inexpensive, off-the-shelf components are used to... (View More) build a light sensor and source, creating a simple spectrophotometer that can measure light absorption. In the second part of this activity, principles of ocean color remote sensing are applied to measure reflectance. Using components that are clearly visible allows students to configure them in different ways. Playing with the instrument design gives students a practical understanding of spectrophotometers, in-water optics, and remote sensing. As an extension of this concept, students are encouraged to think about how ocean color is used to estimate the concentration of chlorophyll to infer phytoplankton abundance, colored dissolved organic matter, and suspended sediments.

This short (11:29 minutes) video features NASA scientists answering a set of student-designed questions related to NASA’s Global Precipitation Measurement satellite mission. The set of twelve questions were generated after students viewed... (View More) animations of GPM data; the questions centered on satellite operations, satellite data, and precipitation patterns and impacts. (View Less)

Emphasizing the synergies between science and engineering, these video clips highlight the research of professional ocean scientists and engineers in various disciplines. The clips are accompanied by additional relevant content including images,... (View More) data visualizations, graphs, animations, and other information. Content has been organized into more than a dozen thematic areas such as Solving Old Problems with New Technology and Small Scale Observations and Large Scale Ideas. All content has been aligned with science and engineering practices from the Next Generation Science Standards, including "asking questions and solving problems" and "planning and carrying out investigations," providing applicable resources for teachers who want to provide role models of effective practice for their students.

This set of three videos illustrates how math is used in satellite data analysis. NASA climate scientist Claire Parkinson explains how the Arctic and Antarctic sea ice covers are measured from satellite data and how math is used to determine trends... (View More) in the data. In the first video, she leads viewers from satellite data collection through obtaining a time series of monthly Arctic and Antarctic average sea ice extents for November 1978-December 2012. In the second video, she begins with the time series from the first video, removes the seasonal cycle by calculating yearly averages, and proceeds to calculate the slopes of the lines to get trends in the data, revealing decreasing sea ice coverage in the Arctic and increasing sea ice coverage in the Antarctic. In the third video, she uses a more advanced technique to remove the seasonal cycle and shows that the trends are close to the same, whichever method is used. She emphasizes the power of math and that the techniques shown for satellite sea ice data can also be applied to a wide range of data sets. Note: See Related & Supplemental Resources for the maps and data files (1978-2015) that will allow you to do the calculations shown in the video. These also include data for different regions of the Arctic and Antarctic, enabling learners to do additional calculations beyond those shown in the videos. (View Less)

Air traffic (and therefore airplane contrails) was halted nationwide for nearly three days following September 11, 2001. Students will investigate whether that stoppage resulted in any changes to cloud cover, temperature and/or radiation. Using the... (View More) MY NASA DATA Live Access Server (LAS), students gather satellite data on each of the three atmospheric parameters around that time frame. Working in teams, they read, compare and discuss two accompanying articles, then use the data from the LAS to create a PowerPoint presentation contending whether it was the lack of contrails or simply natural weather patterns at the time that was responsible for the increase in the range of temperatures. This lesson uses student- and citizen science-friendly microsets of authentic NASA Earth system science data from the MY NASA DATA project. It includes detailed procedures, analysis questions, teacher notes, related links, background information, lesson extensions, and a list of related AP Environmental Science topics. (View Less)

This activity examines the relationship between carbon dioxide levels in the atmosphere and chlorophyll-a measurements in a watershed. Students analyze and compare two Excel plots-one showing carbon dioxide data values from the Keeling Curve and the... (View More) other showing satellite data of chlorophyll-a concentrations. This lesson uses student- and citizen science-friendly microsets of authentic NASA Earth system science data from the MY NASA DATA project. It includes detailed procedures, analysis questions, teacher notes, related links, background information, lesson extensions, and a list of related AP Environmental Science topics. (View Less)

Using the 5E instructional model, students discover the value of using color maps to visualize data. The activity requires students to create a color map of the ozone hole from Dobson data values derived from the Aura satellite. Students then... (View More) interpret that map and compare and evaluate different color scales. Note that this is the Spanish version of Exploring Color Maps: Using Stratospheric Ozone Data. (View Less)
