Identify the colors on the radar. Investigate doppler radar. Materials and Management globe, aluminum foil, string 6 in., large pieces of different colored const. In this activity, students will build their own satellites, collect important imformation about weather, crops, the size of the polar ice caps, the eruption of volcanoes, the amount of water vapor in the air, and the temperature of the oceans. They will also locate distress signals from downed aircraft.
Weather satellites are spacecraft which collect and relay weather information to Earth.
Before the first weather satellite was launched in 1960, forecasters could not reliably track weather across the oceans that cover most of the earth. There are two types of weather satellites. Polar orbiting satellites circle the earth from pole to pole, competing one orbit every 100 minutes. These satellites orbit at an altitude of about 500 miles above the earth's surface and provide coverage of the entire earth four times per day. The second type of weather satellite is the geostationary.
