Active learning ideas
Food labels and additives are the primary tools for consumer communication. This topic teaches students how to navigate the complex information found on food packaging, from ingredient lists to nutritional information panels (NIP). They also learn about the functional roles of additives, such as emulsifiers, stabilizers, preservatives, and colorings, and the regulations governing their use in Singapore.
Activity 01
Groups are given various food packages and must find specific information: the 'use-by' date, hidden sugars, and the function of three listed additives (e.g., E-numbers). They present their findings to the class.
What information is legally required on a food label in Singapore?
Activity 02
Students discuss whether 'natural' additives are always safer than 'synthetic' ones. They share examples, such as beet juice versus artificial red dye, and discuss the pros and cons of each.
Why are preservatives and colourings added to food?
Activity 03
Students 'create' a new healthy snack and must design a label that complies with Singapore's food regulations, including an accurate NIP and a clear ingredient list in descending order of weight.
How can consumers make informed choices using nutritional panels?
A few notes on teaching this unit
Watch Out for These Misconceptions
Ingredients are listed in any order on a label.
Students often don't realize the order matters. Using a 'label sort' activity helps them understand that ingredients are listed from highest to lowest weight, which is key to identifying the main components of a food.
All 'E-numbers' are dangerous chemicals.
There is a common fear of E-numbers. Through a collaborative investigation, students can discover that even common substances like Vitamin C (E300) or Turmeric (E100) have E-numbers, helping to demystify food science.
Methods used in this brief
