Most other liquids exhibit densities between 0. Elmhurst College: What Is Density? Pouring ml of Coke into the liter tank diluted it by a factor of 45, so any change it made to the density of the water would have been minuscule. We work through my density science tabbed booklet and explore the investigation together. Diet Coke contains an artificial sweetener: aspartame. In regular soft drinks, there is more sugar packed into the same space as a diet. This results in one can floating and the other sinking and science teachers everywhere having a trick to go along with their often questionably accurate anecdotes.
Repeat the experiment with a can of diet soda. Does it sink or float? Ask the students how this compares with their predictions. Both the Diet Coke and Coke cans contain 12 fluid oz. Account icon Bouyant? icon in the shape of a person’s head and diet. What To Do Show the students the two cans of cola. If the soda volume of more weighs soda slightly more than the can more, then if we bouyant? the can in the tank of water, diet floats. Aspartame exhibits a perceived sweetness of times that of sugar. You can check that post out here. Complete key to listings.
Many science teachers perform a demonstration in which they immerse sealed cans of Coke and Diet Coke in a tank of water. The can of Coke immediately sinks, while the can of Diet Coke floats. Some instructors have adapted this demonstration as an experiment to teach students the principles of density and buoyancy. The experiments allow students to conduct measurements so that they can devise a scientific explanation for the observed behavior. Density represents the relationship between a substance’s mass and the amount of space it occupies, i. Pure water exhibits a density of 1. Most other liquids exhibit densities between 0. Coca Cola consists mostly of water. But it also contains 39 g of sugars, primarily in the form of high-fructose corn syrup, or HFCS. The HFCS used by Coca-Cola and most other soft drink manufacturers exhibits a relative sweetness of compared to the baseline sweetness of exhibited by sucrose, or table sugar. This relative scale reflects perceived sweetness, which means that HFCS literally tastes 1.
