Here are some words about our current Mantle of the Expert work, which is with a class of year 4 students.

In this Mantle of the Expert unit the children are in role as a team of earth scientists who work in a fictional company called 'Geo Ready' (modelled on New Zealand’s real crown institute ‘GeoNet’).

Working in this role children will have jobs and tasks to complete that will lead to learning about:

a. New Zealand’s geological hazards: volcanos, earthquakes, and tsunami

b. Scientific equipment used to measure land movement/activity

c. How earth scientists at 'GeoNet' decide where to place their different monitoring systems. In making these decisions children will have to consider things such as types of land forms and rocks in an area, environmental factors such as weather, read maps, investigate history of land, look at old land records, and investigate land ownership and explore ways to seek permissions from land owners.

The work will involve inquiry research, writing in a range of genres including letter writing and report writing, reading a range of materials including lots of map-work covering a variety of keys and scales, and mathematical skills including measuring, and diagram/graph work.

We hope you enjoy sharing our learning journey and the discoveries we make! You can also read past learning journeys by selecting from 'Previous Mantle of the Expert Work at Muritai School', which is a tab on the right hand side of this blog page.

Today we spent the morning poring over topographical maps.  We learned how to read the key to look for different information such as mountains, trig points, native forest, gravel roads, cliffs, sandbanks and lots more!  We also learned about contour lines and how they show how steep the land is (when they are close together the land is steep).  We even discovered that some of the different maps we had joined up!

These two found the longest mountain name in New Zealand: Taumatawhakatangihangakoauauotamateapokaiwhenuakitenatahu

Finding maps that join together.

We then spent time working on a logo to go with our company name ‘GeoReady’ and our mission statement ‘When the earth goes crazy we are the experts’.  There was a creative buzz in the classroom as we worked on these and next week we will use our logos to make ID cards for our drama work.  Here are some of the logo designs that were created.

Then we had a visit from Sara Page who works at GeoNet.  It was a great visit.  She gave us a lot of information, showed us some real equipment, answered all our questions, and even brought us all GeoNet magnets and pens to take home!  She also gave us a quiz and five children won prizes, which were very cool little torchlights!  We found out that Sophia’s grandad is one of the managers at GeoNet.  Here is what some of us wrote about her visit:

Sara talking to us

On Friday 17th of May Sara came to visit us.  She works for GeoNet, which is part of GNS.  She’s a public information specialist. She gave all of room 7 a GeoNet magnet and GeoNet pen.  She let us have a turn shaking and feeling an old seismometer.  A seismometer measures how big an earthquake was.  Inside a seismometer there is a rotating drum and this penlike thing.  When there’s an earthquake the pen wobbles and draws lines on the drum.  Although the seismometer is small it is very heavy.  There were 303 earthquakes in Wellington last month!!!!

Holding a seismometer

Sara works for GNS, she works in GeoNet.  My Grandpa John knows Sara very well.  GeoNet studies tsunami, earthquakes, landslides, and volcanos.  Sara told us about some instruments like a seismometer.  

She told us that in April 2013 there were 303 earthquakes isn’t that amazing, and it was only in Wellington.  

Sam B:
I held a real seismometer.  A Seismometer connects to their computers and tells them how big the earthquake was.  It felt about 10kg.  

They hire divers to drill a hole underwater and place a sensory guage to connect with the computers for Tsunmai information.

We got to hold a seismometer it was quite heavy.

Today Sara from GeoNet came to talk about the earth.  We were very lucky to have her.  She gave prizes for questions if we got them right, the prize was a torch.  She answered all our questions.  She gave us pens and magnets and she told us how many days it takes to get to Raoul Island, it takes 3 days.  At GeoNet her job is to tell the public about the earth [and the work they do with geological hazards] and she gets to go around New Zealand every 2 months.   She told us that there were 303 earthquakes last month in Wellington.  Most people only thought there were only 2 or 3 and last year in Wellington there was 3232.  She brought in an old seismometer and she let us hold it and shake it.  Shaking it was fun!  The seismometer is a thing that measures every movement of the earth.  When the earth has an earthquake it will make a funny sound and it is made out a magnet and wire and stuff like that.

Sara told us that once people at GeoNet put up a whole lot of equipment near Mt Tongariro then it erupted and destroyed it. [...]  We received a GeoNet pen and a GeoNet magnet.  There was small quiz for the class of five questions and if you got the right answer you won a small torch.

They have monitors for landslides, earthquakes, tsunami, and volcanos.

She first talked about some of the people at her work and there were jobs.  The jobs were technicians, systems development, websites, earthquake specialists, public information specialists, scientists, volcano specialists and managers.

I might want to work for GeoNet.

Sara gave us lots of interesting information incluidng posters, maps, and booklets - Thanks Sara!
