Density Differences

Our 6th graders designed their own experiments in order to determine which was more dense: a can full of Pepsi or a can full of Diet Pepsi. Each team of students was given a can of each soda, and a bucket filled with water. They had to work collaboratively in order to decide their procedures of their experiment on how to answer the question of "Which is more dense Pepsi or Diet Pepsi?". Once they determined which was more dense the students developed hypotheses on the reasons why,  which led to a debate on artificial sweeteners and high fructose corn syrup.
