The Most Dangerous Volcano July 1 2010

I enioyed making our volcano erupt by using vinegar and baking soda.My group did really well at making our volcano scene. I like learning about how pressure makes a volcano erupt. Next time my group could do better by woking together.

Volcano Report

A volcano is an opening in the earth's crust, through which lava, ash and gases flow. The word volcano comes from the Roman god of fire - Vulcan.

A volcano erupts when the pressure inside the earth builds up and needs to escape. Molten rock, in the mantle, heats up. The magma chamber fills up, then the magma pushes up the vent and out of the crater.

There are three main types of the volcano. One is a cinder cone another a shield or a composite. The most dangerous one is composite volcano because it erupts violently with lava and ash. A volcano can be active,dormant (sleeping) or extinct.

A volcanic eruption can be both destructive and beneficial. Falling ash is dangerous to aeroplanes, can cover buildings and make it hard to breathe. Lava flows and lahars destroy everthing in their paths. However, sometimes eruptions can creature new fertile land.

Ash,lava and gas from deep inside the earth can be very destructive and dangerous during a volcano eruption. However if we are careful we can enjoy the benfits of new land and fertile soil.

The Erupting Volcano - May 5 2010

Eleva wrote this paragraph about an erupting volcano. She has been learning about different kinds of sentences in a paragraph. Can you tell which sentences are complex in her story?

Pressure - April 22 2010

On Monday afternoon we blew up balloons to learn about pressure with Room 14. Next I huffed and puffed to blow up my balloons. After lunch time we stood up and let the balloons fly around. Sometimes lava comes from the ground. It is hot and magma heats up in a volcano.
