In pairs discuss which of the following pictures show inventions. Does any of them show discoveries?
A amphibious car
An amphibious car (2003)
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”
Stephenson’s “Rocket” (1781-1848)
George Stephenson was one of the first men to design engines for the railways which were new at that time. One of the first tracks to be laid was between Stockton and Darlington. Stephenson was one of the first railway engineers and in 1825 he drove the first train along the line. In 1829 came his triumph.
DNA
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.

You need to make a house but you only have fishing nets and many plastic bottles. How can you solve it? (Be sure the walls are solid enough.)
Group work: Group work: how to be a survivor?how to be a survivor?
Suppose you were on a sea journey and
