The ground began to rumble and shake, and the people of Pompeii thought it was just another earthquake. Little did they know, that Mt. Vesuvius was about to explode. The smoke and ash went up into the sky, creating darkness in the middle of the day. A fountain of fire shot upward and the lightning storm began at the same time. Hot tennis balls of rock and ash began to fall from the sky, hitting homes and people. The ash just got deeper and deeper. The town was not only devastated, it was pretty much buried in the ashes. Soon, the rains began, the few people who escaped the town thought the rain would cool everything off. It did, but it also turned the ashes into concrete.
Mt. Vesuvius has been an active volcano since then. It has erupted 40 times since that fateful day. Who knows when it will decide to erupt again?
The book we chose was Volcanoes and Other Natural Disasters. We chose to use the chapter titled "Vesuvius Erupts". This book could be used in conjunction with 3rd grade Georgia Performance Standard S3E1. This standard covers the different types of rocks and minerals and characteristics of those rocks and minerals.
We would teach the lesson on rocks and discuss the 3 times of rocks found in the earth. These are sedimentary, metamorphic, and igneous rocks. Igneous rocks are called "fire rocks" and are formed underground when the heat of the earth's core melts them. They are then called magma and when they erupt from a volcano, they are called lava and as they cool off, they turn back into a solid form of igneous rock.
Because many children from this area, have no way to visualize a volcano, several books, pictures and other resources should be involved in the lesson. One creative resource or experiment that can be used is shown here. We have seen this video and done the experiment ourselves and got the same results as the first part of the video. Enjoy....
