Abstract	The opportunities for outreach activities for professionals and academics in food science are extensive, as too are the range of participants' experience levels and platforms for delivery. Here, we present a set of activities that are readily adaptable for a range of students (ages 10 to 18) in multiple platforms (demonstration table and hands-on workshop). Our activity, collectively called "The Science of a Sundae," has three units, one for each of the three parts of a sundae: the caramel sauce, the cherry, and the ice cream. In each unit we use these familiar food items to illustrate how colligative properties (or, simply, "solutions" for younger students) impact the chemical, microbiological, and sensorial properties of food. We have used these activities to present to over 1000 students and their parents/chaperones. Grade levels of student participants have ranged from 5th grade through high school, and these activities have been presented in the form of a demonstration table at science events as well as a set of three 45-minute workshops in a classroom setting. Educational impact of these activities was evaluated with 7th grade students (n = 77) who participated in the 3-phase workshop. On average, students who took the posttest (after participation in the workshop) scored 36% higher than students who took the pretest (prior to participation in the workshop). These results and instructor observations suggest the merit of this lesson and its adaptability among ages and platforms. (As Provided).
