Science Project- Volcanoe

 For the last couple of days, we have been working on making a valcano. We reasearched top 10 valcanoe's around the world, and chose Arenal Valcano.

The Arenal Valcano is a huge torrist attrction in Costa Rica, it is one of the most active valcanoe in Central America. Since a major eruption in 1968, that killed several people and threw bombs to 5km away. There has been near-continuous axtivity building a lava dome and showing mild explosive activity.

The valcanoe is 7,500 years old, it also doesnt just erupt lava, it also erupts, got gases, rocks, and ash.

aim: make a valcano that explodes.

method: 

Get a flat piece of cardboard. (Or flatten a box).

Get a 700ml bottle and place it in the middle of the cardboard.

Make glue (a little salt, water, flour).

Get a lot of newspaper and scrunch it up into balls.

Use your glue to stick the scrunched up paper onto the bottle. (Repeat this until you have a pyramid volcano shape)

Rip strips of newspaper and place them onto the scrunched newspaper with glue to smooth out the volcano's surface.

Paint your volcano and try to get a reference volcano to paint to.

Put 50ml of H2O2, a drop of food colouring, and a squirt of soap into the bottle of your volcano.

In a beaker put 30ml of water, 2 spat of potassium iodide, and dissolve it by mixing it together. 

Get outside and then put the beaker mixture into the volcano. WATCH IT ERUPT.

how valcanoe's are made:

A valcano form when one tectonic plate moves under another. usually a thin oceanic plate subducts or sometimes moves under a thicker continental, when enough magma builds up in a magma chamber, it makes it self move up the surface and errupts, often causing valcano erruptions.

Conclusion:

I wasnt there for it but i think that it turned out unique because everyone elses valcano erupted and the elephant toothpaste went upwards. but instead our one when in a snake kind of form and went side ways instead of upwards.
