Fourth graders at Harrison Lane, under the direction of Dayla Beauchamp, made "liquid sandwiches" as they explored density. Think of it as a science burrito! Water, corn oil, and dark Karo syrup were measured out equally into graduated cylinders. The students went through the scientific process asking themselves which liquid is the most dense to the least dense. A hypothesis was made, and the experiment conducted. What a surprise to see that the Karo syrup was indeed on the bottom of the cylinder, but water was in the middle! The corn oil was on top! Why was the water denser than corn oil? Conversations were flowing endlessly! What a way to get students talking!
