Our Level 2 Volcanoes textbook contains information on volcanoes found around the world. It includes sixteen lessons on volcanoes. Lessons include Types of Volcanoes, Types of Eruptions, Pyroclastic Flows, Ring of Fire, Mount Saint Helens and Notorious Volcanoes.  Each lesson contains 3-4 pages of written material about volcanoes, a quiz and a kids science activity.

Myrna Martin introduces each lesson in the textbook on a video that can be purchased with our packages and courses. Myrna covers not only the main points in the lesson she also includes extra information on the topic that is not contained in the written material.

The kids science activities are fun and easy to do. Science activities include Mount Saint Helens Flip Book, Notorious Eruptions, Fantasy Island, Seafloor Magnetism, and Frothy Eruptions.

Information on Volcanoes

More information on volcanoes that you may not know. All volcanoes are mountains of fire because they erupt hot molten lava from a vent. Composite volcanoes (stratovolcanoes) form in subduction zones on the continental side of the subduction zone. The great shield volcanoes of the Hawaiian Islands formed over a persistent hot spot in the middle of the Pacific Plate.

Iceland Volcanoes

Iceland volcanoes formed as the North American Plate and the Eurasian Plate are moving apart. Iceland not only sits about two separating crustal plates but it also sits atop a persistent hot spot in the middle of the Atlantic Ocean. The Iceland volcanoes are fed by both the separating plates and the persistent hot spot. The volcanoes frequently erupt because of the magma (molten rock) beneath the island.

A short history of volcanic eruption on Iceland.

Pacific Ring of Fire Volcanoes

The Pacific Ring of Fire volcanoes surround the Pacific Plate forming a horseshoe shaped area that is 25,000 miles long. It is home to 75% of The Pacific Ring of Fire has 75% of the world’s active and dormant volcanoes. Subduction zones have formed a horseshoe shaped ring around the Pacific Ocean. The subduction zones formed as the Pacific Plate is being over ridden by other tectonic plates. This means the Pacific Ocean is getting smaller as the Atlantic Ocean is increasing in size due to the spreading ridge down the center of the Atlantic Ocean.

Great Stratovolcanoes Surround the Pacific Ocean

The volcanoes form in subduction zones where the older and colder Pacific Plate and other smaller plates are being overridden by continental and some younger oceanic plates. Great stratovolcanoes have formed on the continental side of these subduction zones. Mt. Pinatubo, Mt. St. Helens and Mt. Wrangell are examples of volcanoes made of andesite that surround the Pacific Ocean.

Volcano vent

The vent of a volcano forms when magma (molten rock) first reaches the Earth's surface and erupts as a lava flow or tephra. The magma chamber is the place where molten rock collects before an eruption. When sufficient gases in the magma chamber collect in the molten rock it begins moving upward until it reaches the volcano's vent.

Curtains of Fire

The vent of a volcano continues to be at the summit of most volcanoes as they increase in size. Shield volcanoes often have vents on the flanks of the volcanoes when fissures form on their sides. These vents often are long and create "curtains of fire" when the volcanoes erupts along a fissure shooting molten rock into the air.

Mount Saint Helens Eruptions

Mount Saint Helens erupted on May 18, 1980 with an explosive eruption and a landslide they slid into Spirit Lake beneath the volcano. The eruption occurred on a beautiful spring day while many people were taking pictures of the mountain.

Native Americans living in the area were aware of the past history of eruptions on the mountain. Sailors on British ships in the 1850s observed the mountain erupting and recorded it in their logs.

The eruption was covered by television and newspaper. People sat and watched the massive eruption all day on their televisions. People also read about the eruption and the devastation that followed the eruption in newspaper.  It was the first time that a volcanic eruption of this magnitude was covered by television cameras.

All of our science materials have been used by homeschooling families throughout the United States since 1998.


Recommended by AFMS Junior Chair

Ring of Fire Science materials were recommended by Jim Brace-Thompson of the American Federation of Mineralogical Societies.  He found our materials contain a wealth of information for the junior members of the society. He wrote that our books are beautifully designed and illustrated with easy-to-follow instructions for kids.
