PBL Model

My PBL Model 

 We had to make a model volcano as a part of our project. 

                                  how to make the art

1. Find something that looks a bit like a dome.
2.  Find a large surface that would be suitable for your volcano.   
3.   Begin to paper mache the volcano and the base (if you want to)
4. Wait for the paper mache to dry then begin to paint the volcano.
5. For the explosion I used crate paper to make the explosion 3D you can use paint if you want to.  

 Volcano Report

Introduction

This report is about what volcanoes are, what different types of volcanoes there are and what impact they have on us. Did you know that in 1816 mt tambora, Indonesia erupted and 92,000 people died. that was the most deadliest eruption ever recorded.  

                  What Are volcanoes?

                               How do they form?

Volcanoes/nga puia are formed when magma from the mantle gets to the surface, when it gets to the surface it erupts/ngutu as lava and the more the volcano erupts the bigger the volcano gets. Tectonic plates always move even though they look like they don't

                               How do they erupt?

Volcanoes erupt when 2 tectonic plates bump into each other.

Tectonic plates are the lines on some maps.

There is one going right through new zealand and if those 2 plates bump into each other an earthquake or a volcanic eruption/whakaheke will happen.

What impact do volcanoes have on the world we live in?

A volcanic eruption can cause many bad things but also some good things,

Volcanoes can cause destruction, pollution and serious harm.

They can help with farming,metals and rocks/stones

How do they help? (Positive)

The ash from a volcano/puia can help with the crops in a farm.

Sometimes after a volcano has erupted people have found metals inside.

Volcanoes/nga puia can make rocks that are quite helpful one of the helpful volcanic rocks is called pumice, pumice can smoothen your feet.

  The negative effects

A volcanic eruption/whakaheke can trigger earthquakes, floods, tsunamis and avalanches. These can be very destructive and can also harm you badly.

A volcano/puia can pollute the air with its toxic and also extremely hot ash. It could get into a lake and pollute it.  

How many different kinds of volcanoes are there?

There are 3 main kinds of volcanoes there are

shield volcanoes- are almost made of magma they resemble a warrior's shield lying on the ground.

Composite volcanoes- are made up of many layers/paparanga, hardened lava, pumice and volcanic ash.

Cinder cone volcanoes- are the simplest type of volcano they look like this.
