When New England was hit by Tropical Storm Irene in 2011, there was not a satellite monitoring tropical storms that far north; the Tropical Rainfall Measuring Mission (TRMM) was operating in a band between the 35-degree latitudes. The Global... (View More) Precipitation Measurement (GPM) mission will change that. GPM will build upon TRMM's capacity by examining a larger swath of Earth with instruments that are more advanced and more sensitive. This video introduces the GPM satellite, its instruments and their capabilities. (View Less)
This article describes the work being done by scientists to determine the origin of water found in Earth's oceans. A supplemental exploration of the Herschel Space Observatory is included. The article is targeted to children ages 10-12.
This video provides a glimpse into the snowfall research planned as part of the Global Precipitation Measurement (GPM) mission. GPM Deputy Project Scientist, Gail Skofronick-Jackson, reveals the capabilities of the satellite's new sensors, which,... (View More) through increased sensitivity, will help to overcome the challenges associated with measuring snowfall from space. (View Less)
This is a make-it-yourself planisphere designed to show where Kepler is pointing. Learners can use it to locate exoplanets around stars in the night sky. It comes with two wheels: one with coordinate grid for plotting additional exoplanet stars and... (View More) one without grid that is easier to read; and two holders for varying latitudes (one for 30°-50° and one for 50°-70°). The product is updated approximately annually to incorporate improvements and any newly discovered planets orbiting naked eye stars. (View Less)
This is an activity about image resolution. Learners will recreate a solar image taken by the Solar Dynamics Observatory (SDO) using various sizes of building bricks, and discuss how their recreations relate to image resolution. Learners will also... (View More) compare SDO images to solar images from older spacecraft to see how improved technology helps scientists learn more about the Sun. (View Less)
This activity is about planetary rovers. Learners will simulate the challenges in communications that engineers face when driving a rover on Mars. They will particpate as part of a rover team to design and execute a series of commands that will... (View More) guide a rover made of people through an obstacle course simulating the Martian surface. Students will learn the limitations of operating a planetary rover and problem solving solutions by using this simulation. The lesson models the engineering design process using the 5E instructional model and includes teacher notes, vocabulary, student journal and reading. (View Less)
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 online lab exercise focuses on the causes, characteristics and effects of the glacial-interglacial cycle. The sixth in a 10-part lab series on weather and climate, this lab exercise is designed for first and second year college geoscience... (View More) students (majors and non-majors) as well as pre-service STEM teachers. (View Less)
This interactive visualization illustrates changes in Earth's climate. Manipulate a sliding timeline to view the impacts on our planet of four climate related variables: sea ice, sea levels, carbon emissions, and average global temperatures.
