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 purpose of this resource is to determine the latitude, longitdue, and elevation of your school and of all your GLOBE sites. The GPS receiver will be used to determine the latitude, longitude and elevation of your school or of your GLOBE sites. Full description.

The purpose of this resource is to select 15 km x 15 km Land Cover Sample Sites. Full description.

The purpose of the resource is to produce a land cover type map from hard copies of Landsat satellite images. Full description.

The purpose of the resource is to determine the major land cover type at a Land Cover Sample Site. Full description.

In this activity, polystyrene spheres and strong magnets are used to represent the Sun and Earth, and their distinct magnetic fields. Participants construct and use a "field detector" to predict where the magnetic fields are, and "field bits" to form loops and trace the invisible magnetic fields of the Sun and Earth. The activity is designed to be used in an informal public outreach setting. It can ... Full description.

The purpose of this activity is to observe the type and cover of clouds including contrails. Students observe which of ten types of clouds and how many of three types of contrails are visible and how much of the sky is covered by clouds (other than contrails) and how much is covered by contrails. Intended outcomes are that students learn how to make estimates from observations and how to categorize ... Full description.

The GLOBE Cave Protocol Field Guide utilizes existing GLOBE protocols to explore an extreme environment. Caves provide an opportunity to utilize GLOBE protocols to investigate underground environments and compare them to surface environments. Outside the cave, students record elevation, MUC, latitude and longitude, air temperature, relative humidity and air pressure. Inside the cave, students record ... Full description.

The purpose of this activity is to measure the aerosol optical thickness of the atmosphere (how much of the sun's light is scattered or absorbed by particles suspended in the air). Students point a GLOBE sun photometer at the sun and record the largest voltage reading they obtain on a digital voltmeter connected to the photometer. Students observe sky conditions near the sun, perform the Cloud, Optional ... Full description.

The purpose of this activity is to explore the connections between cloud type, cloud cover, and weather and stimulate student interest in taking cloud type observations. Students observe cloud type and coverage and weather conditions over a five-day period and correlate these observations. Students make and test predictions using these observations. The intended outcome is that students learn to draw ... Full description.
