We provide opportunities for young people to learn about technology's
role in tackling poverty. Introduce yourself: Name University Course your studying and any interesting project you worked on during/ outside your course What is EWB-UK? We are a group of students and professionals who use our skills as engineers to provide better resources and solve problems for people who need it the most. Point out to some of the pictures on the slide and mention that we work directly with communities around the world like Nepal, Kenya, Bangladesh etc. on a variety of projects like building wind turbines, wells, safe houses etc. Why are we here? We are here to introduce some of the challenges faced by communities around the world and the approach an engineer takes in devising an efficient solution.

From Science Concept Cartoons Set 2 – Millgate House Education
What do you think? Ask students to discuss the cartoon and decide which character they agree with and why. They may have their own ideas as well. Listen to groups carefully and take one or two ideas from around the class. Like the last slide the idea is to get the students quickly thinking about some of the issues. This is one of the new Concept Cartoons from Millgate House Education From Science Concept Cartoons Set 2 – Millgate House Education

Why did NASA send Mars Rover to find clues of water?
To know more check the source: Water signifies life Earth is the only planet we know that has water and without it life on Earth could not have evolved.
6
Where do you use water? Once the question is up you could either just have pupils shout out answers and reiterating them or use a white board / flip chart to list them down for all to see. Once the list is sufficiently long the next command will have the animations popping up with some of the most common uses of water. Once they have ascertained water is essential for so many activates then provide some basic information about water like: Why does water affect us all? - Water is everywhere. The Earth’s surface is 60% water. We’re made of 75% water. Crucial to survival: Can only live a day and a half without water. Recommended to drink 2-3 L per day (even food is mostly water). We need it for drinking, sanitation, washing, cooking, electricity generation, manufacturing. Our world’s ecosystem runs on it. Related to things like poverty, health, global warming...

Answer on the next slide:
If a person in the UK had to carry home all their water in 2 litre bottles, on average, how many would they need each day? Students write their answers on mini whiteboards as a “show me activity” if these are available. Answer on the next slide: 75 bottles If a half liter plastic drinking bottle is around you can lift it up before the class and show them that in a day over 300 bottles filled with water is used by a single person. Source: 4 bottles 20 bottles 75 bottles 90 bottles
8
On average a person in the UK uses
150 litres of water = 75 two-litre bottles
9
So how many do you think would an average person use in the USA?

386 litres of water = 193 two-litre bottles
13
So how many do you think an average person in Bangladesh would use?
Students write their answers on mini whiteboards as a “show me activity” if these are available. Answer on the next slide:
14
On average a person in Bangladesh uses
46 litres of water = 23 two-litre bottles

Over 1 billion people in the world DO NOT have access to clean water
On average women in Africa and Asia walk nearly 4 KMs to collect water Video: Embed code: <iframe width="560" height="315" src="// frameborder="0" allowfullscreen></iframe> Source for Over 2.2 million people die each year from a waterborne disease: Over 1.1 billion people DO NOT have access to water: On average women in Africa and Asia walk 3.75 kms to collect water Over 2 million people die each year from a waterborne disease
21
We all need water that is clean and safe to drink
We all need water that is clean and safe to drink. What makes water unsafe? The next couple of slides will look at what are the factors that make water unsafe and consequently what can be done to purify water.
22
What makes water unsafe?
Rubbish in the sea Oil leaks from ships Untreated sewage Dirt Use the question on the slide to get pupils involved in the discussion, if answers aren’t forthcoming then prompt based on general knowledge of the surrounding, the video they have just seen etc. Ask pupils to raise their hand if they have an answer, reiterate the answers given or start to list these on the white board or flip chart. If there are some unique ones mentioned asked for it to be explained and reiterate it to the group. Biohazard - medical waste or samples of a microorganism including virus, bacteria or toxin (from a biological source) that can affect human and animal health. Poisonous chemicals – arsenic, heavy metals, pesticides, mercury, lead, zinc, oil, copper, cadmium etc. CONTAMINANTS pesticides cadmium mercury copper lead oil zinc
23
How can we make water clean and safe?
Can solicit answers here if desired. Write the answers given by the class on the blackboard or on a flipchart if possible.
24
Remind pupils about the process of filtration and how it can purify water as seen on the slide. They will now be working in groups to make a filter which will be tested and presented before the class. -First hand out the ‘country fact sheets’ and ‘bill of quantities’ sheet to all groups. If possible write the group names (countries) on the black/ white board so they can see how other teams are doing. -Encourage teams to read the data on the information sheet. They must use their budget allocation to plan for materials to buy for building the filter and if possible use alternate sources or materials (that do not have to be brought from the shop but can be sourced naturally). Remind the class only 1 member of the group can come to the ‘shop’ to collect the materials. -Based on the desired list from each group hand out the material in plastic cups and ensure you keep a tally of their budget vs materials allocated -Walk around the class and guide those teams that are struggling specially with limited funds and design brief. -If a group finishes early allow them to test their filter and carry out multiple repetitions by filtering the same water, and observe it get clearer after each attempt. -If a group is struggling, try to have a volunteer help them out more than other groups, if a group is running out of resources than give them some more using a phrase such as ‘Kenya has received resources as aid from the UN’ and explain how this might happen in a real. Remember to give them warnings before finishing each stage. Below is a rough time estimate for the activity but feel free to tailor it to your requirements: 5 mins – Read country brief 10 mins – Plan filter design and request material from the shop 10 mins – Build the filter 10 mins – Present the design plan before the other groups and test the filter! Once completed: Spend a couple of minutes reviewing the workshop and particularly the teams which did not have much resource and highlight how they were able to complete the task with limited resources. If there have been incidence of teams helping each other out highlight this and encourage such practice. Build a filter!
25
Activity Every team should have a ‘Country Sheet’ and ‘Cost’ sheet.
Read the information for your country. Within your groups: Plan and design your filter Complete the ‘Cost sheet’ and nominate 1 member to buy goods from the shop Nominate 2 members to test and present the filter Remind pupils about the process of filtration and how it can purify water as seen on the slide. They will now be working in groups to make a filter which will be tested and presented before the class. -First hand out the ‘country fact sheets’ and ‘bill of quantities’ sheet to all groups.

‘Everyone has the right to access the technologies
The availability, supply and treatment of water is different around the world but by using our knowledge and skills we can ensure this vital resource is made available to all. On completing the activity request all the teams to leave their filters at the front on display with the country sign on them. Lead the discussion towards unequal distribution of resources and lack of skill to develop from available resources. If there were incidences of groups sharing resources highlight this fact and encourage this habit. If you noticed alternate/ innovative ways by which groups sourced resources then highlight that too. Relate all this in the context of Technology Justice and how it is important to use and share the skills and resources we have to help each other grow and develop. Example of Technology Justice as showcased by one of EWB-UK’s partner organisations in Kenya, MASABI: ‘Everyone has the right to access the technologies that are essential to life.’

I am an MDG child... https://www.youtube.com/watch?v=Sj6q0Apd_cs
Video: Embed code: <iframe width="560" height="315" src="// frameborder="0" allowfull screen></iframe> Based on the age group of the students alter the content and time you spend on this slide You could start the discussion by asking what they had learnt from the video: What is MDG? How many MDGs are there? Can you name some? Eradicate extreme hunger and poverty Achieve universal primary education Promote gender equality and empower women Reduce child mortality Improve maternal health Combat HIV/AIDs, malaria and other diseases Ensure environmental sustainability Develop a global partnership for development You list them on the board/ flip chart as they are being said and link how the workshop today can be linked to all the MDGs Eradicate extreme hunger and poverty – By using water sustainability e.g.. Rain water harvesting water can be made available for agriculture translating into food for the locals. Achieve universal primary education – Developing an efficient water supply system would give children an opportunity to attend school and save time spent on collecting water from distant locations. Safe water also translates into a healthy mind and body thus better attendance at school. Promote gender equality and empower women – Women and young girls will have more time to be involved in productive activities which they would otherwise spend collecting water. Reduce child mortality – better water and sanitation facilities directly translates to health children and mothers. Improve maternal health – better water and sanitation facilities directly translates to health children and mothers. Combat HIV/AIDs, malaria and other diseases – sanitised water supply reduces the risk of waterborne diseases hence lower mortality rate due to water borne diseases like diarrhoea. Ensure environmental sustainability – recycle, reuse and conserve water! Develop a global partnership for development – Organisations like EWB-UK partner with local organisations within vulnerable communities that develop healthy knowledge, skill and resource sharing partnerships.

You’ve seen how precious a resource water is no matter what country you live in, and the previous activity has given you an idea of just how challenging it can be to get clean, drinkable water. Clearly, it’s vital we don’t waste this precious resource. What are some basic things you can do to save water? Let the group come up with some ideas, either list them on the white/board or repeat them to the class. Once you have got some ideas, flick through the next couple of slides as most of them would have been mentioned. What can you do?
31
Turn off the tap while brushing your teeth
Use less water at home Use only what you need when making a cup of tea Turn off the tap while brushing your teeth Also, avoid power showers. It takes 80 litres of water for a bath, but only 30 litres - less than half as much - for an average shower. Take showers instead of baths Wash fruits and vegetables in a bowl of water
