In this month’s “Fun with Science” session at Bowen School Shibalidian, organized by the Royal Society of Chemistry Beijing Local Section and MCF with the help of volunteers from Beijing University of Chemical Technology and the Royal Society of Chemistry Beijing Office, the topic was food. We discussed why fruit and vegetables (being packed with vitamins—especially vitamin C—and fibre) are healthier than high fat/high sugar foods like biscuits and cakes—although the students did admit they enjoyed eating the latter as well! But how do we know how much vitamin C is present in different fruits and vegetables? Take tomatoes, sweet red peppers and apples: can you guess which contains the most vitamin C? In “Fun with Science” we didn’t have to guess—we used chemistry to find out!
