A simple density demonstration involving coke and diet coke. After they answer question 1, I place the Coke into the water and it sinks you may want to test beforehand if you are using tap water and some cans can be off so will actually float instead of sink. For part 2, the change in temperature was determined using the LabQuest instrument. This is a copy of from one of my students.

Record the volume of the water in the cup. From the results of the experiment, there was a slight difference between the densities of Coke and Diet Coke. In other words, the mass of the can must be somewhat less than 1. This will help lower the random error between the measurements. The dissolved salt raises the density of the water ref. Thus it is just possible that a cold can of Coke regular would sink but a warm one might float. I make sure to have them refer back to the demonstration and the density column that I showed them at the end of the demonstration.

Woodworking is a skill, that may take a while to perfect the craft especially if you're attempting to work it out all on your own. Although both cans contain the same amount of liquid, one floats Diet Coke® and the other sinks Coca-Cola Classic®. Within this section students learn about the idea of density and how less dense substances float in more dense substances. To dissolve all the salt, you need to stir the water rather vigorously, for which you can use the large stirring rod. Attempt not to cut corners when it regards the plans. In this experiment, there were several objectives. The can of Diet Coke shown above has a mass of about 370 g, as does a second spare can.

Diet Coke is so named because it is an artificially sweetened, low calorie beverage, on average containing less than one calorie per 8 fl. The coke immediately sinks in the tank of water, while the diet coke bobs up and down and finally comes to a rest at the top of water. Your kidneys signal your brain to release an anti-diuretic hormone when it needs to conserve water. As a final check for understanding I have students perform 5 homework questions. Try to compare the results by using different types of soda cans. The student with the Coke sees that there are 39grams of sugar in a can of Coke. First, this lab was designed to determine the difference, if any, between the densities of Coke and Diet Coke.

Turns out that they are hidden in a sense within the molecular organization of the solution; the solvent allows the water molecules to pack together a little bit better than for the case of pure water. I tested room temperature cans in hot, room temperature, and cold water, and every single time, the Pepsi sank and the Diet Pepsi floated. So even if it is the same amount of liquid, Regular Coke is denser, therefore heavier, and will sink to the bottom of the bucket while a Diet Coke will float.

Goizueta had witnessed a remarkable set of accomplishments during the 1980's. Although both will stain your teeth. A lot of spare woodworking plans can be found on the internet. You may also scan through some woodworking plans to find a notion of different sorts of plans. If the temperature of Coke or Diet Coke changed, but mass and pressure remained the same for each measurements, the density would not change because density is independent of temperature. Sugar slows down the absorption of the alcohol, giving you a steady, controllable buzz.

A humorous note: After one class session that included this demonstration, I found the Diet Coke floating in caramel-colored water, and the empty Coke can beside the tank. Place the object in the cup and fill it with water. Put both cans into a large container of water to observe the behavior of each in water. The woodworking plans which can be found in magazines are largely accurate and simple to follow and you will probably get fantastic effects, in the event you patiently apply each step as explained. From the procedures in this experiment, I learned how to calculate significant figures.

A student had asked if pouring the regular Coke into the water might raise the can of Diet Coke above where it had been floating. Thus, it is possible — even likely — to find cans of regular Coke that are the same density as water or less, and that float as a result. I also learned the importance of reading the protocol and writing down all important information thoroughly in the lab manual prior to lab. S has become an increasing concern of many Americans. This is where that comes from. For the first question students predict what will happen when I place the Coke in the water.

Also, the mass of the can may vary somewhat the ones I measured were somewhere between 12 and 13 g , and it is also possible that the overall size of the can could vary slightly. Which type of Coke is floating? I then tried all the cans in the 12-pack, and I found that about half of them sank, and half of them floated. Based on these data, the precision of my three measurements was fairly low. Coke and Pepsi have since been competing to rein the global market in consumer beverages.
