How did you get to school today? How would you get to hospital if you were ill? How do your parents get to work? If you went on holiday, how might you travel? What’s the strangest way you’ve ever travelled?

Transport disasters We don’t tend to even notice transport infrastructure until it goes wrong!
What makes a successful transport system? You need.. Reliability A path A vehicle Skilled operators Safety Maintenance
NOW IT’S YOUR TURN Let’s look at a flight What vehicles are involved? The path? The skilled people? Maintenance? Safety? Reliability?
Why do we travel? To get to jobs or school To get to healthcare To trade For enjoyment, and communication A LACK OF TRANSPORT INFRASTRUCTURE IS ONE OF THE CAUSES OF POVERTY
What if there wasn’t all this? How far do you have to walk to school? In Mexico, it can take over 5 hours! Who lives near a tarmac road? 1.2 billion people don’t! Whose family has a car? There’s only 1 car for every 2 thousand people in Africa!
What if there wasn’t all this? Who has access to water at home? In rural Africa, many women have to walk more than 5 miles for water!! The average weight of a water container is 10kg! =
If there wasn’t all this, what would you do? LET’S PLAY A GAME!
If there wasn’t all this, what would you do?
WHAT CAN ENGINEERS DO? How can engineering improve lives?
Engineers can use their skills to make things better But they should use appropriatetechnology Uh oh!
Bharpak, Nepal Getting crops to a market is slow and difficult in the mountains It can take over 6 hours on foot!!
Bharpak, Nepal Engineers have designed a GRAVITY ROPEWAY to make the journey easier…
Bharpak, Nepal The journey now takes 10 minutes!! And the villagers can sell more, fresher crops = + + + + The whole village is prospering!!
Kibera slum, Nairobi Kibera is the largest slum in Africa Half the residents are under 15 Most live on £1 or £2 a day Yuk!
Kibera slum, Nairobi Children would have to cross this to get to school!
Kibera slum, Nairobi This is where we need engineers!
Kibera slum, Nairobi Good balance! The final bridge!!
LET’S PLAY ANOTHER GAME! You’re going to build a bridge..
Bridge building There are several types of bridges
Truss bridges Why are they strong?
Truss bridges Triangles are seen in lots of structures:
Your task.. You are engineers who must build a bridge in Nicaragua In the rainy season the river is impossible to pass
Your task… Build a truss bridge to cross a 20cm gap The bridge must support # kg
Is the winning bridge… The one that held the most Or that held the closest to # kg ?
If we get transport we get everything else: a community centre, water, employment, post office, telephone.. A community without roads does not have a way out
What can you do..? Maybe one day you could be an engineer? Tell your parents and friends about what you learnt Ask us questions!!
