This is a set of four, one-page problems about the size of planets compared to earth. Learners may use ratios to compare planets within our solar system or those outside of our solar system with the earth. Options are presented so that students may... (View More) learn about the MESSENGER mission to Mercury through a NASA press release or by viewing a NASA eClips video [6 min.]. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.

This is a set of four, one-page problems about the distance craft travel on Mars. Learners will use the Pythagorean Theorem to determine distance between a series of hypothetical exploration sites within Gale Crater on Mars. Options are presented so... (View More) that students may learn about the Mars Science Laboratory (MSL) mission through a NASA press release or by viewing a NASA eClips video [6 min.]. This activity is part of the Space Math multi-media modules that integrate NASA press releases, NASA archival video, and mathematics problems targeted at specific math standards commonly encountered in middle school.

In this lesson students will investigate nitrogen dioxide levels in the atmosphere over a one-year period. The students will have to look at several regions from around the world to draw conclusions regarding NO2 amounts. From the plots, students... (View More) will have to brainstorm the reasons behind the variability in NO2 concentrations. Detailed procedures, materials, vocabulary linked to an online glossary, and teachers notes are provided. This lesson is from the MY NASA DATA project, which has created microsets from large scientific data sets, and wrapped them with tools, lesson plans, and supporting documentation so that a teacher, or anyone in the interested public, can use authentic NASA Earth system science data.

In this activity, learners draw a circle with a single focus, an ellipse with two foci close together, and an ellipse with two foci far apart, and compare the shapes. Learners then measure the Sun in four images each taken in a different season,... (View More) comparing the apparent size of the Sun in each image to determine when Earth is closest to the Sun. This is the second activity in the SDO Secondary Learning Unit. The activity is reprinted with permission from the Great Explorations in Math and Science (GEMS). (View Less)

In this problem set, learners will calculate the parts-per-thousand measure for different scenarios, including ocean salinity as depicted in the image included. Answer key is provided.

In this activity, learners write space weather reports using current data about the Sun and create a broadcast script to present the researched information to an audience. Several activities are related to this lesson, including "Understanding our... (View More) Sun", "Sharing New Knowledge", and “Making Your Space Weather Action Center" in the Space Weather teacher's guide. (View Less)

In this problem set, learners will analyze a graph of the reflectivity of soil and two kinds of vegetation to understand how scientists use these measures to identify different materials. Answer key is provided. This is part of Earth Math: A Brief... (View More) Mathematical Guide to Earth Science and Climate Change. (View Less)

In this problem set, learners will analyze a table of electrical consumption of appliances when not in use and consider the total consumption in kilowatt-hours (kWh), associated cost and their own consumption when appliances are in "instant-on" or... (View More) "stand-by" mode. Answer key is provided. This is part of Earth Math: A Brief Mathematical Guide to Earth Science and Climate Change. (View Less)

In this problem set, learners will compare before-and-after satellite images of Greece to answer questions related to biomass loss as a result of the 2007 fires. Answer key is provided.
