What do barley fried rice and chamomile tea have in common? They are healthier meal options that Dunearn Secondary School students (foreground) designed for the elderly.

The students designed the meal based on the nutritional levels of different types of food.

They emerged as champions yesterday in the health and food analytics category of the Shell Science, Technology, Engineering and Mathematics (Stem) Youth Innovation Challenge. Minister of State for Education Janil Puthucheary (centre) was guest of honour at the event.

The challenge saw some 580 students apply their Stem skills to create products and solve problems according to the five themes of the competition, which was organised by Science Centre Singapore's Stem Inc and sponsored by Shell. Students from 48 secondary schools took part, with 15 teams taking home top prizes.
