Lake Surprise at Mt Eccles National Park
Hawkesdale is right in the middle of a geologically significant area, recognised by UNESCO as a Global Geopark, for it’s volcanoes, caves, tumuli, sink holes and lava flows. This week you are required to complete two of the following tasks:
- Take a photo of a geologically significant feature near your home – it could be basalt (bluestone), scoria, a rock wall or sandstone building. Upload the photo to Flickr, with the CC license and tag it #kanawinka; #rocks #pics4schools #earth and #geology. See if you can identify whether it is an igneous, sedimentary or metamorphic rock.
- Use CC photos on Flickr to create a Voicethread about the different types of rocks and the rock cycle. or you can add your voice to the one I have uploaded here. Make sure you speak clearly and describe how each of the rock types are formed.
- Imagine you lived in the Kanawinka area 40,000 years ago, when the volcanoes were active. Write a short story (at least 400 words) about what life was like for you – your family, food, shelter and activities – when one of our volcanoes erupted (Mt Eccles, Tower Hill or Mt Rouse). Check out the images at the Budj Bim Tours site to see rock huts, fish and eel traps and the wetlands.
- Design a reptile area (20 metres square) for our threatened species of striped legless lizards, corangamite water skinks and other snakes and lizards. What features do they need to survive? Bruce Mirtschin (from Hopkins Moyne Landcare Group and HADDAC) will assist us to construct this area at the Hawkesdale Common, opposite Apex Park. Design interpretative signs about the different reptiles for visitors to the area. You will find more information about the species of lizards that live in Victoria at the Museum Victoria site.
- Create a 60-second science video for the competition that explains clearly a science concept – how igneous rocks are formed, how slow cooling produces larger crystals, the different types of volcanoes, how fossils are formed, what weathering and erosion does to a landscape etc. Videos must be uploaded by November 7th to qualify for the competition (great prizes!).
Year 8 Assessment tasks:
You may choose one of the following tasks:
- Test on Friday 29th October (Revision questions on pages 142 and 143 must be completed)
- Make your own My Studiyo Quiz (at least 15 questions with images) and embed it in your blog.
- Create a Voicethread or Photostory about the types of rocks and rock cycle
- Film an entry for the 60 second science video about types of rocks and the rock cycle; how fossils are formed; tectonic plates and continental drift; how life began on earth or another relevant topic (see me before you start your storyboard).
To celebrate Earth Science week I have compiled a list of my top ten sites for learning about volcanoes:
- Volcano Live web cam List of links to 23 web cam sites at volcanoes around the world.
- How Volcanoes Work, sponsored by NASA
- Virtual Volcano Explorer from Discovery Channel
- Forces of Nature from National Geographic
- Interactive Volcanoes
- Volcano Project by Oregon State University
- Volcanoes On-line – an Oracle ThinQuest project – by students for students
- Global Volcanism Program by the Smithsonian Institute
- This Dynamic Planet by USGS – Science for a Changing World
- Volcanoes for Kids – images, different types, how they form and erupt.
Maybe you know of another great site to learn about volcanoes? Just add it to the comment section below.
Today we had an exciting opportunity to link up with Ng Young C. Y., a Hong Kong national who is a driving force behind the establishment of the Hong Kong Geopark. He is an expeerienced presenter, member of and advisor to numerous committees and boards of management for conservation of geologically significant areas. Young had lots of information about the difficulties establishing a geopark in a metropoliton area, wonderful images of the park and it’s significant features and ways they market the geopark using appropriately named dishes of food (such as the tempura prawn volcano!).
Students learnt about the igneous rocks that we passed around, drew a labelled cross-section of a volcano and were able to ask questions about the geology of the park. We also look forward to tomorrow’s presentation by Ian Lewis about caves, sink holes, fossils, volcanoes and bats. Ian is an ex-teacher, geologist and member of the Kanawinka Global Geopark committee. He was born on the side of a volcano, loves caves and diving and will be sharing lots of his photos and knowledge about all things volcanic!
On Friday I will be attending the “21st Century Learners in Rural Communities” seminar in Melbourne, so you will have some work to go on with. Go to the Interactives Rock Cycle site and work through the activities:
- Types of Rocks
- How Rocks Change and
- Rock Cycle Diagram
- Test Your Skills (15 Questions)
When you have completed the test, take a screen shot of your results or save the assessment result page that comes up at the end and send it to me at my gmail address. I am still waiting for the Google doc worksheet (“Plates of the Earth”) from all except four students. This needs to be sent to my email too.
If you finish the test questions, go to FUSE and copy the Learning Resource Package ID number into the Search box: WMCL9X
These are the Kanawinka Global Geopark resources for you to explore. Try “Rock Back in Time“; “Down to Earth – Paleotraveller” and “Shaping the Land“. If computers and/or the internet is unavailable you will complete work from the textbook – read “Weathering and Erosion” and answer the review questions.
You could also go to the Volcano Web Cam site and check out some volcanoes in real time. Choose ten different volcano cams and find their location on a map of the world. Create your own Volcano Google map, showing the longitude and latitude of each site. Which of these are in the “Pacific Ring of Fire“?
The Tramline Virtual Volcano Field Trip helps you to answer the following questions:
- How are volcanoes formed?
- How can they create islands?
- What kind of destruction can they cause?
- How do volcanoes affect our environment?
- Where in the earth can you find active volcanoes?
- Are there volcanoes on other planets?
- What are the different types of volcanoes?

Jules Verne wrote a novel called “Journey to the Centre of the Earth”, about an expedition starting inside a volcano in Iceland. Although the novel was fiction, scientists have been digging bore holes into the earth for decades, trying to discover what lies beneath the earth’s crust. The deepest mines only go down about 4km, but scientists in Russia drilled a research hole to over 12km deep on the Kola peninsula. After 26 years of drilling, the temperature reached 180C and the project was abandoned. Scientists have estimated that the earth has a radius of 6370km and the temperature reaches about 7000C.

Yesterday the Warrnambool Standard reported that, after more than two years, UNESCO has declared an area of land from Colac to South Australia as Australia’s first Geopark. The volcanic features of the area, including Tower Hill, Mt. Eccles, Lake Condah and Camperdown’s crater lakes will be marketed as Kanawinka Geopark, which may increase tourism in the area. Geoparks are one step down from World heritage listing and are awarded to regions of geological significance which incorporate human economic development.
