Studies say 1 in 5 children drinks 10 cans of fizzy drinks a week
To some schools,  the machines are worth tlO.000 a year Not drinking enough water can affect concentration
They say too many fizzy drinks can affect your concentration and can also interrupt your sleep,  especially the ones with caffeine in.
Drinking water gradually throughout the day means the brain is rehydrated and that boosts the capacity to learn
Teachers at Mason Moor primary in Millbrook said they had already noticed
an improvement  in pupils'   concentration.
Head teacher Sue Nicholson  said:   "Children are beginning to appear quieter
and calmer and much better able to concentrate - skills which we hope will
have a marked effect on improving their education attainment."
Carbonated soft drinks
More than  5,560 million  litres of carbonated soft drinks are consumed every year in the UK.  Such drinks are crammed full  of sugars and acid that attack our teeth and may resTin dentaí

Fizzy drink sales  restricted
Fizzy drinks have been linked with childhood obesity The sale of fizzy drinks to school   pupils  has been limited  in another education authority in the united states. The Seattle Schools  Board,   in Washington  state,   has narrowly voted to extend a five-year drinks  contract with Coca Cola -  but has placed restrictions on sales to pupils.
Middle school  pupils will  not be allowed to buy carbonated soft drinks during school  hours.  And vending machines will  also have to offer healthy alternatives  -  such as water and fruit juices.
The decision in Seattle  represents a compromise between financial
pressures on schools to keep the drinks  contract - and the demands
of health campaigners to reduce the consumption of fizzy drinks.
There have been growing calls for an improved diet for young people
- and the sale or fizzy drinks  in  school   has  been particularly
criticised.
But the vending machines  have also raised  revenue for schools  - with
the coca Cola deal  in Seattle claimed to be worth hundreds of thousands of dollars  for school   funds.
