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:

  1. Types of Rocks
  2. How Rocks Change and
  3. Rock Cycle Diagram
  4. 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:

  1. How are volcanoes formed?
  2. How can they create islands?
  3. What kind of destruction can they cause?
  4. How do volcanoes affect our environment?
  5. Where in the earth can you find active volcanoes?
  6. Are there volcanoes on other planets?
  7. What are the different types of volcanoes?

Our Solar System

This week we celebrated the Winter Solistice, the “shortest day of the year”, when the earth’s axial tilt is farthest away from the sun. In the southern hemisphere, this is June 20th or 21st, when the sun rises later and sets earlier than any other day of the year.Check out “Astronomy Connections” for an interactive explanation of the seasons.

Next term, Year 6 and 7 students will be starting a unit of work on our solar system.  This 6 minute YouTube video from the Hayden Planetarium and American Museum includes every satellite, moon, planet, star and galaxy in the Known Universe. Anyone with an iPod Touch can install the following applications to help them to learn about our Solar System (Thanks Jenny Ashby for your comment!)

  • 8Planets – animations, information and quiz about our solar system
  • Planets by Q continium – A 3D guide to the solar system for aspiring astronomers.
  • Grand Tour 3D – Space travel on a budget
  • planetFacts – size and distance scale and dictionary
  • NASA app including images, videos, information about launches, when you can sight, orbit trackers and countdown clocks.
  • Stars by Nelix displaying 88 constellations – does not use network.
  • Star Walk ($2.99) 5 stars astronomy guide
  • Space Images by NASA – You can rate, email and save images.
  • Star map ($11.99) Planetarium in your hand with 350,000 stars!
  • ABC TV has a free vodcast “Voyage to the Planets” that you can download or subscribe to.
  • Don’t forget Stellarium on your netbooks
  • Celestia (space simulation) is another free (Open Source) download for Windows, Linux, and Mac OS X.

Students will have a choice of activities including:

  • Write a postcard “Back to Earth” about the conditions on one of the planets around our sun.
  • Write a brochure for tourists about space travel.
  • Use “Voicethread” , “Powerpoint” or “Photostory” to describe our solar system to aliens from ‘outer space’.
  • A 60-second science video advertising one of the planets as a tourist destination
  • Create a digital story about the planet you would most like to visit and how you would survive there.
  • Use “Blabberise” to record an alien invader’s report back to his home planet about the Earth’s solar system.

This week and next week we welcome Kelly Tolsher, student teacher from Ballarat University, into our classroom. Kelly will be taking year 7 and year 8 science classes as part of her third year teacher training. She will be starting a unit on Earth Science with each class. You can access the following Digilearn activities at school:

Shaping the Land

Tectonic Boundaries

Journey to the Centre of the Earth

The following links are internet resources that are accessible both in and outside school:

Down To Earth – Download four rich earth science interactive educational resources including “Undercover”, “Rock Back in Time”, “Paleotraveller” and “Metals Matter”.

A problem-based learning activity – Hands On Oil Exploration.

Evolving Planet – Take a tour through time – visualize millions of years of evolution in just a few clicks!

Forces of Nature (Tornadoes, volcanoes, earthquakes and hurricanes) interactive site to build your own volcano.

Volcano Explorer – Explore a virtual volcano.

Extreme Science – Eathquakes, volcanoes and more.

Dynamic Earth – Interactives to show the structure of the earth, plate tectonics and continental drift.

National Geographic has excellent photo galleries about plate tectonics.

What is the deepest hole in the earth?

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.
