What do weather balloons and satellites do? Students investigate how weather balloons are tracked by radio after release into the upper atmosphere. They report on what information is collected and how it is used to construct weather maps. Students investigate how weather satellites record and send photographic images of Earth to state weather bureaus. Satellite images show cloud cover and measure wind speeds. A useful site to explore satellite images is the Commonwealth Bureau of Meteorology: Students work individually or in small teams to make a rain gauge out of a measuring cylinder in a beaker with a funnel on top. Place in an open position in the school grounds and record rainfall over several days. Students record their observations in a journal. Students create a story about someone caught in a natural disaster. Students demonstrate their understanding of the relationship between: movements in the Earth's crust and mantle changes within the atmosphere natural disasters. Application activities Effects wheel Students draw several concentric circles. They select a particular natural phenomenon such as flooding and place its name in the centre. They divide each successive circle into double the number of segments as is in the previous circle. In the segments of each circle students list the flow-on effects from effects in the previous circle. Further resources The following resources contain sections that may be useful when designing learning experiences: Digilearn* Exploring Earth's structure: Earth probe -- Students drill to the centre of the Earth. Students measure the temperature and pressure
