Volcano project - Sam and Liam

Our task in science is about researching and creating a volcano and blog about the steps. The questions and tasks we have to do are...

Our volcano research:
  1. Where is it? Western United States
  2. What is its name? Yellowstone Caldera (also known as Yellowstone Supervolcano
  3. Is it extinct? No
  4. Dormant or Active? Yes  
  5. What type of volcano is it? The Yellowstone Supervolcano is a Caldera type meaning the volcano its self have collapsed inwards into itself due to lack of magma, making it a large volcanic crater. 
  6. How are these types formed (Include diagram)? caldera is a volcanic feature formed by the collapse of a volcano into itself, making it a large, special form of volcanic crater. A caldera collapse is usually triggered by the emptying of the magma chamber beneath the volcano, as the result of a large volcanic eruption.

-(Yellowstone Supervolcano)

Next steps are to plan our model,
What are we going to make it out of? We will be making the outside of the volcano with flour and water.
How will you make it erupt? 
What landscape will you paint it on? A red rock enviroment 
Who will bring what materials? Liam will bring the bottle for the main structure of the volcano.
And the final step.........................................BUILDING TIME 

Update:
So far we have constructed our volcano though we didnt get the time to paint but the next step is to make them erupt!
Here is a photo of our caldera volcano.

Science - Pumice

What is Pumice? A light and porous volcanic rock formed when gas-rich froth of glassy lava solidifies rapidly.

How does  it form from  volcanoes? When lava cools quickly in water the gas bubbles get trapped as the lava soldifies.

What are its properties? Composition- Very thin translucent bubble walls/ Density- Very light weight due to air bubbles/ Buoyancy- Since they are light weight they will usually float in water/ Abrasivity- They are abrasive which is why they are so good at removing dry skin off feet/ Color- Commonly pale in color ranging from white, cream, blue or grey to green, brown and black.

How is it similar to hokey pokey? When out of heat they both cool rapidly and harden very fast trapping air bubbles in the process.
