I tried to stir the imagination and enthusiasms of students to take risks, to do what they were most afraid of doing, to widen their horizons of action.

Bronze is a metal alloy made from copper and tin. Copper makes up the larger amount, usually between 80 to 95%.

Metals are strong and are useful for making tools, buildings, bridges and other structures where strength is important.

Alkali metals such as sodium, potassium, rubidium, caesium and francium are extremely reactive elements, just putting them in water can result in an explosion! They are carefully stored in oil to prevent this happening.

While aluminum is the most common metal found in the Earth's crust, the most common metal found on Earth is iron, mostly because it makes up such a large part of the Earth's core.
