A discovery=An invention
an amphibious car
This is the first car that can travel safely on water and on land.When moving on water,the wheels of the car turn sideways and move into the body.The underneath of the car is strong enough to sail as a boat.It is a prototype and is not yet being produced for sale.This is an interesting modern invention.
Stephenson's "Rocket"
George Stephenson was one of the first men to design engines for the railways which were new at that time.It was a great invention.
The structure of DNA
This was a discovery of Francis Crick and James Watson and published in 1953.These two scientists were the first to show that our genes consist of two spirals of DNA(called the double-helix).This work led directly to the human genome project in 2003,which discovered the Structure of DNA.
Work out the rules that will help you decide what a discovery is and what an invention is.
A discovery is (finding out something already existing in nature but not yet known).
An invention is (something that was created by human beings not existing before.)
