This iOS app for iPhone, iPad and iTouch, allows families and educators to investigate and learn about the Sun at home, at school, or anywhere. It provides 13 free, easy to use, hands-on activities, plus live images of the Sun from NASA's SDO... (View More) satellite, videos of the Sun, and more. Each activity includes material lists, step-by-step instructions, and detailed explanations. Some of the activities and media pieces are also available on the project website. The activity materials are widely available and inexpensive. (View Less)
This Science On a Sphere (SOS) module is designed to help the public better understand the story of water on Mars and how we're learning more about it. It portrays the mystery of what happened to the water on Mars in the context of a detective... (View More) story. NASA's MAVEN mission (Mars Atmosphere and Volatile EvolutoN) will help solve this mystery by studying the Martian atmosphere, how it has changed over time, and how it interacts with the Sun and the solar wind. The module also delves into Mars exploration, featuring past, present, and future Mars missions, and includes an activity comparing images of water-related features on Earth and Mars. It will help people understand that a planet's climate can change over time and how learning more about Mars helps us learn more about Earth and other planets as well. Resources included are: script, SOS playlist and datasets, background and tips for the docent or facilitator, and image comparisons of water-related features on Earth and Mars. (View Less)
This guide provides instructions on how to make color pictures using images downloaded from the WISE archive. An overview of what digital images and FITS files are is followed by a discussion on the basic process of how gray scale images are... (View More) adjusted, assigned color, and added together to create a color picture. Five different image processing programs are provided to the users, along with the pros and cons of each program, and links for installing and using each one. There is also a review of the various image artifacts that may be found in WISE images. (View Less)

In this self-guided lesson, students read and learn about the history of Earth imaging and the Landsat satellite. They develop interpretation skills as they play a game that involves inferring the subjects of various Landsat images.
This is an activity about the shape of the Earth’s orbit. Learners will first use elements of the orbit of Earth and Pluto and an apparatus using string, a pencil, and pushpins to accurately draw an ellipse, showing the nearly circular shape of... (View More) the orbits of Earth and Pluto. They then measure real images of the Sun in each season, determining the apparent size of the Sun to see if it changes throughout the year. By determining the apparent size of each Sun image and by seeing the shape of Earth's orbit, learners will confront the misconception that seasons are caused by changing distance of the Earth from the Sun. Finally, learners reflect on the results of the Sun-Earth Survey, which is Activity 2 in this set. This is Activity 4 in the Great Explorations in Math and Science (GEMS) guide titled Real Reasons for Seasons: Sun-Earth Connections. The resource guide is available for purchase from the Lawrence Hall of Science. This activity recommends use of an overhead projector. (View Less)
