Food additives in chemistry lessons Authors Ivana Mladenovic Jasminka Korolija Ljuba Mandic Igor Matijasevic Dragan Marinkovic Abstract Food additives are common food components and they should be studied in chemistry classes. This paper describes a lab lesson for high school seniors (17-18 years old). They tested some physical and chemical properties of four unknown additives. Using the test results the students had to figure out which four of the ten additives from a list given had been tested. The students worked in small groups. All four correct additives were chosen by 26 % of students (groups), three correct additives by 29 % and two correct additives by 45 % of students.
