Typically completed by 10-14 year olds, students work collaboratively on a five hour project or challenge in self-managed groups. During the project, they use a CREST Discovery passport to record and reflect on their work. Afterwards, students communicate their findings as a group presentation.
Each pack provides teaching guides, kit lists, example timetables and suggested starter activities to help you run your day. Find out more about CREST Discovery Awards.
What next? • If you have used this challenge to work towards a CREST Discovery Award you can enter your work into the Youth Global Challenges competition • Maybe you could choose the best design in your class, or ideas from several designs and use that to build a working hand washing device in your playground • Get involved in the movement to help ensure the Global Goals are met by joining the campaign www.globalgoals.org and looking at Global Goals 3 and 6.

2 Info Sheet: Material costs You will need to buy materials to make your hand washing model. Each modelling material represents a ‘real’ material you would use if you were building a hand washing device in Kenya. These can be divided into: • Locally sourced materials – these are available close to the school and in the village e.g. bamboo, plastic bottles, rope. You should aim to use as many locally sourced materials as possible as they are more sustainable • Imported materials – these will need to be transported from a town or city further away. Generally they cost more to produce and you have to pay for the transport into the village. As an important part of your design you will need to balance the cost of materials with their quality and their impact on the environment. Budget Your budget is 125 credits. Keep track of how much you are spending on your cost record sheet. Anything you use not listed on this sheet is free. Trading Once you have bought materials you can’t just give them back if you don’t use them…so think carefully before you buy! If you do have material that you don’t need you can trade with other groups.
