Rocks and minerals are all around us. Earth’s crust and part of its mantle are made of rock. Rocks are made of minerals and have different properties. The properties of rocks include color‚ texture‚ luster‚ and hardness. We use rocks and minerals in many different ways. The steel in our buildings is made with iron‚ which is a mineral. The clay and glass used in our pottery and dishes are made of a mixture of rocks and minerals. We even need minerals to stay healthy‚ and we get them from a variety

intrusive rocks harden slowly beneath the surface of the earth‚ and often form large mineral crystals within the rock. Granite is a good example of an intrusive rock.Porphyritic intrusive rocks have large crystals embedded in a matrix of smaller crystals. Pegmatite is the only porphyritic rock on the Science Olympiad list.Extrusive rocks harden quickly during a volcanic eruption and are usually smooth-grained. Basalt is the most common form of extrusive rock. |IgneousName |Classification|Description

in the rearrangement of molecules‚ but doesn’t affect their internal structures. When you make rock candy‚ you are creating a physical change. When sugar and water mix together‚ they are not forming a new substance‚ sugar dissolves‚ but it doesn’t disappear. So when you crystallize it‚ it still has the same chemical structure‚ the only thing that changed is the physical appearance. When we create the rock candy it will take about a week or more for it to fully form. While we do this project we hope

more crystals at a more rapid pace. The purpose of my experiment is to grow a large amount of crystals on a wooden skewer. Rock candy is a candy made with sugar that I chose to attempt to grow on a wooden skewer. This delicious candy is actually crystallized sugar that I grew from a sugar-water solution. In this science fair project I have learn how to grow my own rock candy and determine if you use different types of sugar‚ it will change the growth rate of your sugar crystals. When I added

Moon rocks Colwell 7 brought back from the Apollo age astronauts shows that at some point the moon did have a magnetic field as strong as the Earth’s at some point. From analyzing the way the rock formed‚ the scientists can determine how long the Moon had a magnetic field. From their research they have discovered that a magnetic field persisted for much
