Iron

Iron is a chemical element with the symbol Fe and atomic number 26. It is a metal that is commonly found in the Earth's crust and has been used by humans for thousands of years.

Properties of Iron

Physical Properties: Iron is a silver-white, lustrous metal that is malleable, ductile, and has high tensile strength.
Chemical Properties: Iron is reactive and readily forms oxides, such as rust, when exposed to air and moisture.
Magnetic Properties: Iron is ferromagnetic, which means it is attracted to magnets and can be magnetized.

Uses of Iron

Iron is used in a wide range of applications, including:

Construction and engineering (e.g., in the production of steel)
Manufacturing of machinery, tools, and vehicles
Production of household items, such as cookware and cutlery
Medical treatments (e.g., in the form of iron supplements for treating anemia)

The resources above cover the following skills:

LIFE SCIENCE

Ecosystems: Interactions, Energy, and Dynamics

Obtain information from literature and other media to illustrate that there are many different kinds of living things and that they exist in different places on land and in water (e.g., woodland, tundra, desert, rainforest, ocean, river).

EARTH AND SPACE SCIENCE

Earth’s Systems

Make observations from media to obtain information about Earth’s events that happen over a short period of time (e.g., tornados, volcanic explosions, earthquakes) or over a time period longer than one can observe (e.g., erosion of rocks, melting of glaciers).

Collect and evaluate data to identify water found on Earth and determine whether it is a solid or a liquid (e.g., glaciers as solid forms of water; oceans, lakes, rivers, streams as liquid forms of water).
