A volcano in my notebook!!! project for second grade

A volcano is a mountain topped with vents, holes, and craters. When the volcano erupts, lava, ash, cinders, dust, and hot gas can pour out the top. Magma (when it's deep in the ground) or lava (when it reaches the earth's surface) is very hot, liquid rock. When the lava cools down, it turns into hard rock. Ash is a gray powder that results from material being burned in the volcano. Ash can be carried in the air for many mile

~ Volcano Terminology ~
Magma Chamber, Crater, Vent, Cone, Bomb, Pyroclastic Flow, Ash Cloud
Acid Rain, Cinders, Lahar, Landslide, Sill, Dike, Dome, Tephra, Lava Flow
~ Types of Volcanoes ~

~ 4 TYPES OF VOLCANOES ~
(FYI: There are approximately 600 active volcanoes on Earth today.)
1. Hot Spot Caldera Volcanoes:
(the most violent and explosive eruption style)

Answer: Olympus Mons (on planet Mars)

3. Cinder Cone Volcanoes:
(the most abundant volcano in the world, and least deadly & destrucive volcano)
Cinder Cone volcano Ejecta includes:
Bombs, Blocks, Cinders, Clinkers, Glass (obsidian), Pumice and Ash
Obsidian (black volcanic glass) and Pumice (only rock that floats on water)
Cinder Cones...
Cinder Cone volcanoes look a little like ice cream cones.
Mmm...cinder cones and lava cake.
What is your favorite flavor of cinder cone?

4. Composite (Strato) Volcanoes:
(the most violent and deadly mountain style volcano, has all eruption hazards)
Above and Below: Composite Stratovolcanoes with Glaciers
Composite Stratovolcanoes erupt with both lava and ash.
Types of Volcanic Eruptions:

Lavaboarding anyone?
Notice the difference between the Aa and Pahoehoe lava below:
Aa lava is viscous, jagged and chunky and moves very sloooowly.

 B.-Use the links below to solve the problem or complete an activity:
 
1.-My Favorite Volcano. Pick a volcano to explore. Visit sites like Volcano World and Earth's Active Volcanoes to learn as much as you can about your volcano. Mark the location of the volcano on the map and attach a picture from the Internet. Describe the interesting characteristics of this volcano. Compare and contrast two different volcanoes.
 

 
2.-Create a Volcano Model
Okay, the baking soda volcano is the kitchen equivalent of a volcano, not a real one. It's cool all the same! The baking soda volcano is also non-toxic, which adds to its appeal.
Difficulty: Average
Time Required: 30 minutes

Here's How:

  1. First make the 'cone' of the baking soda volcano. Mix 6 cups flour, 2 cups salt, 4 tablespoons cooking oil, and 2 cups of water. The resulting mixture should be smooth and firm (more water may be added if needed).
  2. Stand the soda bottle in the baking pan and mold the dough around it into a volcano shape. Don't cover the hole or drop dough into it.
  3. Fill the bottle most of the way full with warm water and a bit of red food color (can be done before sculpting if you don't take so long that the water gets cold).
  4. Add 6 drops of detergent to the bottle contents. The detergent helps trap the bubbles produced by the reaction so you get better lava.
  5. Add 2 tablespoons baking soda to the liquid.
  6. Slowly pour vinegar into the bottle. Watch out - eruption time!

Tips:

  1. The cool red lava is the result of a chemical reaction between the baking soda and vinegar.
  2. In this reaction, carbon dioxide gas is produced, which is also present in real volcanoes.
  3. As the carbon dioxide gas is produced, pressure builds up inside the plastic bottle, until the gas bubbles (thanks to the detergent) out of the 'volcano'.
  4. Adding a bit of food coloring will result in red-orange lava! Orange seems to work the best. Add some red, yellow, and even purple, for a bright display.
  5. If you need more detailed instructions or information about the chemical reactions involved in the volcano, I also have a step-by-step tutorial and a video tutorial.

What You Need

  • 6 cups flour
  • 2 cups salt
  • 4 tablespoons cooking oil
  • warm water
  • plastic soda bottle
  • dishwashing detergent
  • food coloring
  • vinegar
  • baking dish or other pan
  • 2 T baking soda
