INTRODUCTION Few things excite the imagination as much as a volcanic eruption‚ one of nature’s magnificent spectacles‚ which can result in devastating consequences. The very word “volcano” brings to mind thunderous explosions‚ rivers of fiery orange lava‚ and images of smoking destruction. The actual capacity for destruction is not overrated -- volcanic eruptions are one of the most devastating of all geologic hazards. There are about 700 potentially dangerous volcanoes in the world‚ and about 50

answer the question‚ “Can a material form a new substance when exposed under a given condition?” Climbing Colors To extract the hidden colors that makes up the main colors of various felt-tipped markers. Cup of Lava To demonstrate the effects of salt on oil by creating a "lava lamp" in a cup. Dissolving in Liquids To explore the extent to which different solids will dissolve in water at a given temperature and compare the results. Dissolving Solutes To find out how solutes behave when mixed

assisted in the making of this hypothesis was the recalling of the fact that objects with lower temperatures (such as air or water) become denser. Two experiments that I found to be quite similar to this one were the Density Column and the Bubbling Lava Lamp. The Density Column measures the density of seven different liquids by layering them on top of each other. By doing this experiment‚ one is able to find out which liquid is the most dense; with the order ascending

and when it spews out it is called lava." Mrs.Crystal exclaimed‚ "Yes! That is correct! It flows down‚ burning everything in its path. Over a week or so‚ it cools down and hardens‚ because on the surface of Earth‚ it is much cooler than the inside of the Earth‚ which is over 1000 degrees! It turns so hard it becomes a kind of rock.... Jess.. what is it?" Jess said‚ "An.... igneous rock?" "Fantastic!" The igneous rock is basically a lump of cooled‚ hardened lava."

the towel‚ here are some things you may not yet have tried: Use mulch: Mulch can be organic‚ such as bark or simply allowing grass clippings to stay on your lawn instead of bagging them after you mow. Or it can also be inorganic‚ such as plastic or lava rocks. Mulching is obviously the opposite of aerating your lawn. This form of residential weed control can keep weed seeds from reaching the dirt or it can keep pre-exiting seeds from sprouting. Since mulching will also kill the grass underneath it

Make a Big Dry Ice Bubble We will need a large bowl or a cup with a lip around the top‚ water‚ A strip of material or cloth‚ Soapy mixture for making bubbles (water and some dishwashing liquid should do the trick) and Dry ice (Be careful with dry ice as it can cause skin damage if not used safely. Adults should handle dry ice with gloves and avoid directly breathing in the vapor). Place your dry ice in a cup and add some water (it should start looking like a spooky cauldron). Soak

bruising or bleeding events. Blood viscosity‚ like most things in medicine‚ has a happy medium. Volcanologists have a big interest in viscosity‚ too. The viscosity of molten rock or magma determines how easily a volcano will erupt‚ and what shape the lava flows and resulting mountains will take on. The researcher would observe that knowing the time it took to travel through the column of a liquid‚ the height of the column‚ the density of the sphere‚ and the density of the liquid‚ the researcher can
