The purpose of this activity is to learn how contour maps can be made by hand. Students plot data from GLOBE schools on a map with latitude and longitude lines and draw contours based on the values plotted. A suggested extension and how to use this activity as an assessment is included. Full description.

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 have students learn to use the hydrology instruments and collect the hydrology data accurately. In the classroom, students practice using the instruments or kits for protocols, exploring the range of measurements and sources of variation and error. Full description.

The purpose of this resource is to define a soil characterization site. The following factors are defined: location, latitude, longitude, elevation, aspect (the direction of the steepest slope across an exposed soil site) and landscape position and slope (describes the contours of the land at the soil characterization site). Full description.

This resource provides guidance on site selection for the GLOBE Atmosphere data collection protocols. Instructions for building an instrument shelter, a snowboard, an ozone measurement station, and a wind direction instrument are included. Full description.

The purpose of this resource is to investigate the idea that every dynamic system has energy and matter in different forms. Full description.

The purpose of this resource is to investigate the center pixel of a homogeneous land Cover Site in order to understand that individual land areas are part of a larger land system. Full description.

The National Atmospheric Deposition Program monitors wet atmospheric deposition (chemical constituents deposited from the atmosphere via rain, sleet and snow) at over 220 National Trends Network sites throughout the United States. This site contains a long-term, high-quality database of atmospheric deposition for research support in the areas of acid rain, air quality, water quality, agricultural ... Full description.

This module provides three activities that explore the potential impact of climate variability and change on Earth's most abundant resource, water. Although each activity is designed to tap specific skills and knowledge to yield scientific results, the broader intent is to stimulate thought about the long-term impacts of a warmer planet. Through participation in these activities, students will observe ... Full description.

The GREEN program provides ideas and information related to creating a watershed-based educational project and is geared toward taking action to protect watersheds. There are exercises and action steps for various aspects of watershed management including monitoring, analysis, research, policy issues and background information. The site allows groups to enter their watershed monitoring or action project ... Full description.
