Comparing the amounts of land and water on Earth's surface leads students to discover why it is called the water planet. Students examine photos of Earth taken from space, analyze the results of a globe toss game and compare ocean sizes using pieces...

The URL opens to the investigation directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. The teacher's guide will begin with a two-page module overview and a list of all standards addressed. This is Investigation one of four found in the Grades K-4 Module 2 of Mission Geography. The Mission Geography curriculum integrates data and images from NASA missions with the National Geography Standards. Each of the four investigations in Module 2, while related, can be done independently. (View Less)

Multiple activities illustrate the concept of changes in bodies of water over time. Emphasis is placed on the use of remote sensing to monitor changes in water bodies that are due to climate change, erosion, drought, human intervention and natural... (View More) events. Using clay and water, students evaluate the impact of rising water levels on different coastlines and on coastal cities. Students also analyze satellite images showing three examples of changes caused by water: the melting of the Greenland ice sheet, the flooding in the Midwestern region of the United States and the drought effect on Africa's Lake Chad. The URL opens to the investigation directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. This is Investigation 4 of four found in the Grades K-4 Module 2 of Mission Geography.

This math problem demonstrates the concept of geometric progression, through an example of a million dollar contract between an employee and an employer. Application of the concept of geometric progression to social cause activism is addressed. This...

This resource explains how to estimate the global consequence of a person's actions to quantify what it is to "think globally." To lend meaning to the result, it introduces "order-of-magnitude" thinking. Three examples, on the global impact of a... (View More) short drive, a little water and an hour of light, are described.

Scientists use estimates as a check on more precise measurements; estimation is an easy way to quantify early hypotheses that can be tested or checked later in formal analysis. This article describes a number of examples of the use of estimating the... (View More) answers.

In the state of Maryland, a local politician once claimed that sea level is rising because there are too many people putting boats on the open ocean. Could that result in a significant sea level rise, perhaps even destroy low-lying nations such as... (View More) Bangladesh?
