Featured Silver project Featured Gold project Build a catamaran In this project, students will design and build a simple model catamaran. Students will then use their model to test the effectiveness of a range of different types of sail. Test the waters with the below extract: You should start this project with some research. Find out how sails ‘work’ – what are the aerodynamic principles of a sail? Detecting food fraud Your students will investigate how to use chemical analysis to detect food fraud. Get the flavour of this project with the extract below: Periodically, a new food scam hits the headlines… • 1985 - Several Austrian wine producers added ‘antifreeze’ to sweeten their wine • 2004 - Specially purified water turned out to be bottled tap water and contained a suspected carcinogen (cancer-causing chemical) • 2013 - DNA testing showed that several processed beef products contained horse meat Gather information on the main types of sail, including the more traditional types of sail. What are the advantages and disadvantages of each? Design and build a model catamaran for use on water if a suitable lake or pond is available. Now you’ve built your model, you should use it to test the effectiveness of different types of sails. Decide how you are going to make your tests as fair as possible.

Determine the concentration of several brands over a range of prices and compare their value for money. Are ‘value’ brands actually good value? You have undertaken the role of an analyst commissioned to test the products. Produce a report for your customer, detailing your evidence and conclusions. Remember, your evidence must stand up in court, so you need to make sure that you can answer any objections that may be raised and disprove any counter-arguments.
