The primary and secondary sectors
One of the main reasons people move is to find work. The economy and its jobs are divided into three sectors: primary, secondary and tertiary.
Workers take raw materials from natural resources: farmers, shepherds, fishermen and miners. Most of these jobs are in rural and coastal areas. In Spain, only about 5% of jobs are in this sector.
Workers transform raw materials into manufactured products. Most of the work is done by factory workers in factories, with big machines, but some is done by craft workers in workshops, with small tools.
From raw material to product
You need cardboard (6 × 14 cm), four bottle tops, two wooden kebab sticks, two straws, a balloon, tape and an elastic band. Tape two pieces of straw under the cardboard and push the sticks through them to make the axles. Make a hole in the centre of each bottle top and push them on as wheels. Put a straw into the balloon and close it with the elastic band, then tape the straw on top of the car. Blow up the balloon, let it go… and see whose car is the fastest! Making cars is a very important secondary sector industry in Spain.
