The biggest event on Watershed Landcare's calendar is over for another year. The Green Day environmental expo for year five and six students from schools across our region was held at Mudgee Showground last Thursday. The theme of this year's Green Day was GoMAD - go make a difference - and the event coincided with Threatened Species Day and Outdoor Education Day. Other workshops focused on the themes of reducing waste, water and energy consumption with presenters from Central Tablelands Local Land Services, Mid-Western Regional Council, Red Hill Environmental Education Centre, NetWaste, Niche Environment and Heritage, Barnson Pty Ltd, Royal Agricultural Society, Crave Natural and Rosby Sculptures in the Garden. Our keynote speaker, Ruben Meerman, delighted students and teachers alike with his spectacular science demonstrations. With the aid of liquid nitrogen, lasers and ordinary household items like food colouring and balloons, Ruben demonstrated simple scientific concepts like evaporation and condensation which helped to illustrate more complex ideas like water circulation in the atmosphere and how it affects climate. Watershed Landcare would like to acknowledge the support of Mid-Western Regional Council, Office of Environment and Heritage, Central Tablelands Local Land Services, Peabody Energy, Moolarben Coal, Red Hill Environmental Education Centre and Niche Environment and Heritage. Event is supported by Watershed Landcare and is a part of the NSW Government’s Local Landcare Coordinators Initiative.
