How Do You Make A Model Of A Volcano Explode?
An exploding model volcano creates a dramatic science project or home learning activity. The explosion, called a volcanic eruption, comes from pressurized gasses within the volcano. The build-up of gasses causes the volcano to erupt, spewing molten lava—rock so hot it becomes burning, moving liquid—to flow out of the volcano, along with ash, smoke and debris. The National Aeronautics and Space Administration (NASA) Earthwatch website provides photos from space of recent volcanic activity all over the earth. Add to the model volcano learning experience by using books and websites on volcanology, the study of volcanoes. Place layers of newspaper over the work surface to protect it from the volcano. Use scissors to cut the top off the bottle where it widens below the opening. Angle the cut so that one side of the remaining part of the bottle is an inch higher than the other. The University of Montana’s Montana Bureau of Mines and Geology website advises cutting the bottle at an angle
