Salt is a mineral that is essential to all animal life, but is toxic to most land plants. Salt is found in the sea, in your blood and sweat and in solid form as rock salt away from the sea.
Salt is collected to use for making food either by mining a deposit of rock salt, or by evaporating salty water until only the salt is left behind.

A salute is a formal gesture of respect. Salutes are most often used by the military, but are also used by organisations like the Scouts.

Salvation Jane, also known as Patterson's curse or Viper's Bugloss, was a garden plant in Europe but once introduced to Australia it became one of the worst weeds in the country. It grows to about 60cm tall and has purple flowers. It is toxic and can kill some animals like sheep and horses if they eat too much of it.
Samoyeds are large, long-haired white dogs from Siberia. They were bred to herd reindeer, to pull sleds and to keep their owners warm at night. They are a very energetic breed and need lots of space and regular exercise or they will get bored and destructive. They are friendly dogs and don't make very good guard dogs. One of their interesting features is they don't have a 'doggy' smell and they don't shed much, so are classed as 'hypoallergenic'.
Sand is something that beaches are made of. Beach sand is made up of ground up rocks and fragments of shells. Beach sand can have quite large bits in it compared to garden dirt. Desert sand is just made from ground up rocks.
The colour of sand varies depending on what kind of rocks or shells went into making it.
