The purpose of this resource is to introduce students to the concept that sometimes there is no one "right" answer to a question or measurement. Students learn to be careful when searching for a right answer to questions such as 'What time is it?' by comparing multiple measurements of the time of day. Students gain an intuitive understanding of the characteristics of imperfect measurements. Using ... Full description.

The purpose of this resource is to learn about latitude and longitude while developing math skills. Students begin by asking the simple question: 'Where Am I?' Then they learn about the magnetic Earth and the use of compasses and angles. Students also learn about the difference between relative and absolute locations. Throughout this activity, students practice using a variety of math skills. Full description.

The atmosphere is a mixture of gases including nitrogen, oxygen, carbon dioxide and other trace gases. Additionally, the atmosphere contains small, suspended liquid and particle matter called aerosols. Aerosols come from various sources, both natural and anthropogenic (man-made). Aerosols are important to study and monitor because they have direct and indirect effects on regional weather and global ... Full description.

Using the Internet as a resource to locate and graph scientific data, students will explore the seasonal changes in precipitation for the Costa Rican Region. They will generate and analyze satellite data for precipitation to identify the two seasons of Costa Rica and relate their importance to the travel industry. Full description.

One of the strongest observed ENSO events of the century began to unfold in 1997. Fortunately, an extensive network of satellite and ocean buoy instruments was prepared to monitor and record the historical event. In this lesson, students will collect data from the MY NASA DATA Live Access Server to understand how scientists detect the onset of El Nino conditions and the reversal to La Nina conditions ...
