This is a Flash-based interactive tool kit. It allows users to watch real-time NASA satellite images of the Sun and Earth. A thumbnail viewer lets them explore and compare solar and terrestrial data from a variety of NASA missions and ground-based observatories. In addition, the viewer contains video interviews with scientists and other experts. Computer-generated visualizations and additional NASA ... Full description.

This collection of thirteen cards depicts Solar System objects such as planets, comets, asteroids, and the Sun. The front of each card displays a color image of a Solar System object; the back provides facts about the object. The Hubble Space Telescope card contains the directions for the game.

The science of astrobiology is concerned with the question of whether or not life exists on other planets. This educator's guide presents eight activities in which younger students investigate this question and explore topics related to the search for life beyond their own planet by using some of the same strategies that astrobiologists use. They will express their opinions on the existence of alien ... Full description.

This educator's guide consists of nine sequential activities for younger students, in which they acquire content knowledge and conduct investigations to compare and contrast Mars and Earth. They will begin by examining images of the two planets, learn about the instruments used to make them, and use the knowledge they have gained by examining images of Earth to begin analyzing images of Mars. The ... Full description.

This educator's guide features eight activities in which younger students use brainstorming, observations, and experiments to learn about the Sun. They will begin by learning that light is our means of studying the Sun, use spectroscopes to separate white light into its component colors, and learn that there are other forms of light outside the visible spectrum. Then the students will conduct experiments ... Full description.

Energy from the sun reaches the Earth and some is absorbed by the air, land, and water. Some of the energy is reflected back into space, meaning it does not heat the land, air, or water. In this lesson students will read a color plot of Earth's absorption of the sun's radiation. They will evaluate causes for difference in absorption rates at different points around the world and draw conclusions about ... Full description.

Snow and ice are both precipitation, that is, the processes that remove water from clouds. Clouds, regions of the atmosphere with high relative humidity, are made of droplets of water and perhaps bits of ice. Even though water is much denser than air, these droplets and ice crystals are small enough to be suspended by random upward air motion. When these droplets or crystals join together, gravity ...

In this lesson, students will play the role of a member of an International Team of Marine Biologists tasked with predicting and monitoring possible harmful algae blooms. They will evaluate changes in the ocean's chlorophyll counts from 1997-2007 using data sets from MyNASAData website, draw conclusions about how the chlorophyll-a levels in the ocean may effect its ecological characteristics and infer ...

Elementary GLOBE is designed to introduce students of grades K-4 to the study of Earth System Science (ESS). Elementary GLOBE forms an instructional unit comprised of five modules that address ESS and interrelated subjects including weather, hydrology, phenology, and soils. Each Elementary GLOBE module contains a science-based storybook and classroom learning activities. Five (5) books are included ... Full description.

A learning activity for the Scoop on Soils book in the Elementary GLOBE Series. Each student will make predictions about the properties of various soil samples. Then they will examine several types of soils and record their observations. Next, they will learn about soil profiles and horizons by both examining a soil sample in a jar and by creating a soil profile flip chart. The purpose of the activity ... Full description.
