Metal is made up of a chemical element that is made up of single atoms that are lined up in a pattern in a crystal structure (atoms that repeat itself many times to line up in a pattern.) Some metals are called metal ore. Meaning it is a metal mixed with a different mineral or rock, the other part is an element. An element is the “materials” of matter. Metal is useful to man because it can be molded more easily than stone, and it is a good conductor of heat and electricity. There are many kinds of metal, copper, aluminum, iron, and steel. But the two kinds of metal I am going to use for this project is copper and aluminum. Copper is one of the most widely used metal except iron. One of the greatest abilities of copper is that it can form many alloys. Alloy is to combine two metals for it to be annealed. Anneal or annealing means to make it stronger. Aluminum was discovered by Charles Hall, aluminum is also one of the most widely used. Aluminum is known for its strength and lightweight. Metals have two types, non-ferrous metal and ferrous metal. Non- ferrous means that it does not contain iron, and of course, ferrous metals are compound metals that contain iron. A compound metal is two or more elements that is combined together. Two non-ferrous metals are copper and aluminum, and two ferrous metals are iron and steel. Strength is how much weight the material can hold, and toughness is the ability to absorb pressure until it cannot get anymore. Some…
Why are metals useful?
metals are good conductors of heat and electricity
most non-metallic elements are poor conductors of heat and electricity
There is a range of metals, lots of different uses, and where they are found?
Where do we get metals (iron, zinc, copper, lead, gold, silver) from, what are they used for?
make a comparison of the properties of non-metals and metals and to explain what makes metals useful eg consider the properties - heat/electricity conduction, melting/boiling…
Wood, Metal and Plastics
There are three main types of timber: hardwoods, softwoods and manufactured boards. Here are a few examples:
Properties and colour
Metals can either be ferrous or non-ferrous:
★ Ferrous metals contain iron and small amounts of other metals. Almost all ferrous metals
are magnetic. But one major disadvantage of many ferrous metals is that they rust and
therefore protective coats…

GARRETT METAL DETECTORS!
Congratulations on the purchase of your new Garrett AT
Pro™ metal detector. This enhanced metal detector has
been specifically designed for use in more challenging
environments such as mineralized grounds and iron-cluttered
relic and coin hunting areas.
The AT Pro includes Garrett's exclusive Target ID technology
and patented discrimination features. Two indicator scales
allow you to see the detector’s discrimination setting (Lower

Metals in Soils
Soils are formed from the decomposition of parent material (bedrock and organic material) over time. Naturally, soils are composed of different elements, particles, and components that are held together in a matrix. Soil properties vary according to the formation processes, protolith(parent material), and local climate in which they were formed. By their composition, soils have a natural background level of these elements that can be compounded by several…
reactions between metals and their salts
Introduction: Some metals are more reactive than others. In this experiment, a strip of metal is added to the solution of another metal’s salt. If the metal is more reactive than the metal whose ion is in the solution, this metal displaces the less reactive metal ion from the solution. This process is repeated with all the metals and all the metal salt solutions. Collecting this data will determine the order of reactivity of the metals.
Aim: To determine…

Alloy: An alloy is a mixture or metallic solid solution composed of two or more elements. Alloying a metal is done by combining it with one or more other metals or non-metals that often enhance its properties. For example, steel is stronger than iron, its primary element. The physical properties, such as density, reactivity. The term alloy is used to describe a mixture of atoms in which the primary constituent is a metal. The primary metal is called the base…
Overview of Basic Metal
Compared with precious metal, basic metals are common metals that can be found in plentiful supply. Copper, zinc, aluminum, steel, tin and lead are examples of some of the more popular types of basic metals. The performance of basic metals is an excellent way to watch economic activity around the world, because these are the actual inputs used in manufacturing, construction and production. Companies cannot build their products or expand their facilities without relying on…
