Third World Countries

1. Third World Countries By Emma, Lauren and Amy

2. Why some countries have no water: Some countries have no water because their government don’t have enough money to pay for new wells to be built. It was only when the water aid company donated sanitation money to help that they started to be able to build wells. About 6% of people out of every country disagreed with having help from outsiders.

3. What We Think We Can Do To Help Uk & other countries can raise money to help these countries to build a factory for water purification and working toilets with clean water in every house. This would then mean that less people would die from the deadly diseases due to the sanitation in the country.

5. What your money can buy ! • £3 could pay for a first aid bag and their weekly needed stuff e.g. Clothes, food, water and nappies • £5 could pay for a bag of cement to build a latrine slab in Ghana • £15 is enough to give one person a lasting supply of safe water, sanitation and hygiene education • £25 could pay for a mason to protect a spring in Uganda • £50 is enough for two days of hygiene education training in a village in Tanzania • £100 could pay a mason to build a hand-dug well in Nigeria • £150 could pay to train two community members to maintain their village water supplies in Ethiopia • £200 could buy a locally built rope pump in Mozambique • £385 could pay for a school sanitation block for 150 boys and girls in India

6. What you can do to help ! • You Can :- • Campaign • Donate money, phones or clothes • Raise Money • Gives so much money every month • Events • Volunteers

8. The Archimedean Screw. The Archimedes’ screw is a machine historically used for transferring water from a low-lying body of water into irrigation ditches. The machine consists of a screw inside a hollow pipe. The screw is turned (usually by manual labour or windmill). As the bottom end of the tube turns, it scoops a volume of water. This amount of water will spiral up in the spiral tube as the shaft turns, until it finally pours out the top of the tube and feeds the irrigation syms.

9. Continued… The contact surface between the screw and the pipe does not need to be perfectly water tight because of the relatively large amount of water being scooped at every turn with respect at the angular speed of the screw. Also, water leaking from the top section of the screw leaks down into the previous one and so on, so a sort of equilibrium is achieved while using this machine, thus inventing a decrease in efficiency. The screw does not need to turn inside the casing but, can be allowed to turn with it in one piece.

10. Tools they need to build wells and helpful solutions • Blacksmiths tools – especially anvils, leg vices, hand operated pillar drills • Carpentry tools – especially large carpenters’ vices, metal jack planes and tri-planes, drawknives • Engineering and Metalworking tools – especially HSS twist drills, metric taps & dies, hand operated bench grinders • Bicycle repair tools – especially spoke spanners • Shoe repair tools – especially complete sets of individual lasts • Auto mechanics’ tools – especially HD screw jacks, tyre pressure gauges, foot-pumps • Electrical repair tools – especially multi-meters, desoldering equipment • Arc Welders (240V)
