8 9705/33/O/N/16 © UCLES 2016 10 Many families enjoy camping holidays. When camping in remote areas, personal washing facilities may be limited. You are to design a portable washing facility that could be used on a camping holiday. The product must be: • easy to assemble; • able to be used by children and adults. 11 Many schools support charities through fundraising events or collecting donations. You are to design a collection box to be situated at the entrance of the school that will enable staff, students and visitors to donate coins. The collection box must: • give an electronic and/or mechanical response when a coin is donated; • securely contain donations which are collected at the end of each school day.
