Penshurst Volcano Discovery Centre and Mt Rouse

Mt_Rouse#3

Today we visited the Penshurst Volcano Discovery Centre to learn about our local volcanic history and the formation of our landscape. After completing a worksheet at the Discovery Centre we went up Mt Rouse to this quarry site, which clearly shows the two eruptions – a scoria layer on the bottom and a basalt lava flow on the top (with soil and vegetation above that layer). We learnt about Maar volcanoes, formed when magma erupts into a water table and massive amounts of steam are produced, blowing material out of the crater. Tower Hill is an example of a Maar volcano. Mt Rouse is a scoria cone, produced when lots of gases shoot material into the air, where it cools and falls into a cone shape. Mt Eccles is a fissure volcano, formed when lava escapes from a split in the earth’s crust.

Year 8 students finished their Earth Science Assessment tasks today. Kirsten’s My Studiyo Rock Quiz  and Maddy’s My Studiyo Rocks! are great examples of student-created, online tasks. Georgia produced an excellent video using Photostory that is available at TeacherTube.

After walking down Mt Rouse we had a BBQ lunch and planted about 1,000 trees at Green’s Lane, Hawkesdale. One of my students asked “Why are we planting trees?”

  • To reduce erosion – the tree roots hold the soil together
  • To provide habitat for insects, birds, reptiles, mammals and other organisms
  • To provide shade and shelter for stock
  • Trees use carbon dioxide to produce oxygen and store carbon
  • Trees add value to farms
  • Trees reduce salinity by lowering the water table
  • Trees reduce evaporation from the creek and keep the water cooler
  • Aesthetic reasons – they look nice!

Please leave a comment below telling me two things you learnt at the Volcano Discovery Centre and what you enjoyed most about the day.
