My Favourite Metal – Aluminium
Aluminium is the most common metal to be found in the earth’s crust (8.1%) but it is never found in its pure form. Scientists believe that this metal was known to man as early as 1787. Pure aluminum, a silvery-white metal, possesses many desirable characteristics. It is light, it is nonmagnetic and nonsparking, stands second among metals in the scale of malleability, and sixth in ductility.In its early days aluminium was too expensive to be used by everybody. It wasn’t until a few discoveries in the 1800s that made extraction of aluminium cheaper. As it became easy to extract aluminium from aluminium oxide and extract large amounts of it from bauxite, hence began an era of cheap aluminium.

Peer Reviews
Here's what a star student thought of this essay
Quality of writing
Spelling, grammar and punctuation appear fine. The pictures do not add to the essay as they are poor quality. The layout of the essay could be improved to be split into clear subheadings.
Level of analysis
The candidate starts with a few basic properties of the metal but does not explain the significance of the melting or boiling point figures. This would show deeper scientific understanding. The candidate explains the history behind the metal and current uses. This should have been presented in a more concise format as the writing appears waffly at the current time. The uses of the metal are presented as a monotonous list and what would have been a better way would be to explain why the metal is used in this instance.
Response to question
The response to the topic of aluminium is a basic one. It covers basic properties of the metal and the history and uses of the metal today. The essay is well rounded but lacks scientific depth beyond GCSE knowledge as it just appears as a bunch of facts that have been researched and bunched together. References are not included.
