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...

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.
This activity is about viewing the planet Mars (and others) through a telescope. Learners will go outside on a clear evening to view the planets and other celestial bodies for themselves. Using sky charts and other resources, and possibly in... (View More) partnership with a local astronomical society or club, children and their families view Mars with binoculars and/or telescopes. The children who have participated in the other Explore: Life on Mars? activities may serve as docents at this public, community event, sharing what they have done and learned about what life is, the requirements for life, and the possibility for life on Mars now — or in the past! It is recommended that the viewing event be paired with the hands-on experiment within the Searching for Life activity if space and time allow. It also includes specific tips for effectively engaging girls in STEM. This is activity 8 in Explore: Life on Mars? that was developed specifically for use in libraries. (View Less)
NASA's Hurricane and Severe Storm Sentinel (HS3) mission uses NASA's Global Hawk Unmanned Aerial Vehicles (UAV) to study tropical storms and hurricanes. This nine-minute video describes the mission, reveals details about the Global Hawk aircraft,... (View More) and offers a glimpse inside the command centers of both the ground-based pilots and the scientists who analyze satellite images to assist in flight navigation. The video concludes with information about getting students involved directly from the classroom through computer monitoring of the Global Hawk's flight patterns and participating in live chats with the ground-based pilots.

This article explains the role of the tilt of Earth's axis on seasonal changes. An accompanying exploration dispels the commonly held misconception that distances between the sun and Earth are a factor. The article is targeted to children ages 10-12.
This two-sided poster presents images and information about ozone. The front features a series of color Earth images; each image reflects total ozone readings taken every October from 1979 to 2012. The poster back contains information about ozone... (View More) under the following headings: What is Ozone?, Chemistry of the Ozone Layer, Measuring Ozone in the Earth's Atmosphere, Timeline of Stratospheric Ozone Depletion and Observations, How the Ozone Hole Forms, and A World Avoided. In addition, the back contains two activities: Visualizing the Ozone Hole and a Color by Number worksheet. (View Less)
Using three images from the Wide-field Infrared Survey Explorer (WISE) mission, students measure and analyze infrared light from objects to identify Brown Dwarfs and Ultra-Luminous Infrared Galaxies (ULIRGs). The lesson includes a teacher’s guide,... (View More) student worksheet and PowerPoint presentation (which contains the three images to be analyzed). (View Less)
This is a set of three activities about how scientists study other worlds. Learners will explore and compare the features of Mars and Earth, discuss what the features suggest about the history of Mars, and create a model to help them understand how... (View More) scientists view other worlds. The activities help to show why scientists are interested in exploring Mars for evidence of past life, and address the question: "Why are we searching for life on Mars?" It also includes specific tips within each activity for effectively engaging girls in STEM. This is activity 4 in Explore: Life on Mars? that was developed specifically for use in libraries.

This activity focuses on the relationship between science of looking for life and the tools, on vehicles such as the Mars Rover, that make it possible. Learners will create their own models of a Mars rover. They determine what tools would be... (View More) necessary to help them better understand Mars (and something about life on Mars/its habitability). Then they work in teams to complete a design challenge where they incorporate these elements into their models, which must successfully complete a task. Teams may also work together to create a large-scale, lobby-sized version that may be put on display in the library to engage their community. The activity also includes specific tips for effectively engaging girls in STEM. This is activity 6 in Explore: Life on Mars? that was developed specifically for use in libraries. (View Less)
This article describes the multi-camera instrument (Multi-angle Imaging SpectroRadiometer or MISR) aboard the Terra Satellite; participants use information from the article to complete a crossword puzzle. A supplemental article entitled, "Clouds and... (View More) Earth" is included. The article is targeted to children ages 10-12. (View Less)
