I liked film-making, but the most difficult thing was the editing. I found it tormentingly difficult.

Tree resin which has been fossilized is known as amber, it sometimes contains plant material or small animals that were trapped inside.

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.

Gold is shiny and doesn't corrode, this means it is a great metal for making jewelry.
