In 1969, an explosive shower of meteorites fell outside the town of Murchison in country Victoria. Containing organic material as well as space dust grains older than the solar system, the Murchison Meteorite has become one of the most studied meteorites and a treasure trove for science. Hear about an eye-witness account of its fall to Earth and see samples of the meteorite in the National Mineral and Fossil Collection at Geoscience Australia.

Geoscience Australia produces a range of educational resources (ga.gov.au/education), including webinars on various geoscientific topics for school children. These webinars are designed to be used for classroom or home learning. They are standalone products that do not require preparation or follow-up by teachers, although this is encouraged. The webinar 'Australia's Seafloor: What's on it, who cares and how do we map it' is designed for upper primary students (Years 4-6). It is delivered by marine scientist Rachel Przeslawski and introduces the techniques and uses of seabed mapping, with a focus on Australia, as well as some of the fascinating marine animals found on the seafloor. Length: 23 minutes.
