Science Fair Project About Coke And Mentos Reaction

Though many people will think there is a lot of bad in soda, technically it’s just carbonated water, which is basically “gas that’s called carbon dioxide that has been dissolved under high pressure” (sciencebuddies.org). When one opens a can of soda pop the carbon dioxide in it is released out causing the bubbles in the drink, and the best part for this project is that one can choose their own way to do it, yes they may have to follow what the recipe calls for but they can choose their favorite flavors and their own color for it like if they wanted to they could make a bacon flavored pop but it might not taste the best but the point would be that it would be their own idea.

The Mentos and soda react due to nucleation. When the carbon dioxide from the soda mixes with the Mentos, the carbon dioxide is squeezed into liquid it’s looking for a way out. It’s trying to hook on to it can and those things are nucleation sites. Since the Mentos are coated with A TON of sugar that is also contains tons and tons of nucleation sites which causes pressure to build up and BAM It explodes.

Is A+C a chemical reaction? Yes, because of serval chemical changes happening to the solution before and after. I came to this conclusion by using three pieces of evidence. The three pieces of evidence were a ph imbalance, a dramatic density rise, and a change in electroconductivity.

Margaret Milcoff, a student of Mill Creek Middle School, participated in an activity called the science fair. Her topic was “Does temperature affect the growth of basil plants?” Margaret has a rich desire to absorb all of the facts of the future, so she did this particular science fair experiment to find out if simple plants, such as basil, would be able to survive the deadly affects of global warming. Margaret used the scientific method through her trials of the science fair. So without further a due here is Margaret’s very successful and meticulous science fair journey.

the effects of various gases on water, to experiment if different gases would change the pH of liquid solutions. To carry out the investigation, three gases, nitrogen, oxygen, and carbon dioxide, were dissolved into 100 mL of distilled water each. While the gases were being added to the water, there were fast-paced bubbles speeding around because the gas was present in the bubbles. Once the liquid was saturated, it was, then, measured for any changes in pH. If the pH was at 7, the pH was neutral. If the pH was higher than 7, it was alkaline. Finally, if the pH was lower than 7, it was acidic. The independent variable was the type of gas and the dependent variable was

It’s mostly due to a process called nucleation, where the carbon dioxide in the soda is attracted to the Mentos (they are awfully cute). That creates so much pressure that the soda goes flying. We then built nozzles that make the opening smaller and that makes the geysers go even

The purpose of my science fair project is to show that kids are more than just their labels. At the beginning of my project I did research on labels and how they affect students at school and at home. Later on I made a 2 test which one was visual and the other was read out loud. I tested on as much people as I could. After a couple of weeks I analyzed my data and divided what into groups. I did the same tests on every person no matter age or grade.The results I got were very impressive students that were looked as the “bad kids” or “not smart” kids, got the best grades on the test versus the kids that are seen as the smart ones got lower scores. These results show that students are more than the labels given there's is more to us than what

The second main factor that increases efficacy is temperature. Andrew D. Raynes’ main result is that the temperature of the soda does change the effect on the height of a Mentos geyser. When pertaining to heat, it produces a large amount of energy to create a higher geyser (Raynes). Temperature and pressure are two main contributors that affect the levels of carbonation in soda. Carbon dioxide remains in the solution in a sealed bottle because of the force of pressure keeping it in. The lower the temperature, the less amount of pressure is in the container

It was finally Friday, August 28, and I was eager to go to school. Friday, was the day our classroom got to do the Diet Coke Mentos Project. For this project we needed the following: two liters diet coke, mentos, tubes, thermometer, a beautiful sunny day, a bunch of excited fourth grader and an awesome teacher, who let us do this cool project. We were so happy to do this project we could not wait until that moment.

I chose to do my Scientific Method experiment on a topic of something bothersome in my household, ants. Lately, I’ve had an ant problem in my kitchen, despite how impeccably clean its kept. I have kids, a small Chihuahua, and didn’t want to use anything with chemicals, therefore, I wanted to find a safer and natural method to repelling the ants.

You have probably seen the coke and Mentos experiments on the internet and wondered “what causes for the explosion to happen?” You might think that Mentos has something in it that might cause the explosion, but it actually has a lot of sugar on it, with a very rough surface (microscopically). Because of this It give a Mentos plenty of nucleation sites, which means, that the bubbles, or carbonation, has something to attach. Though one might think the explosion from a Mentos dropped into a soda is a chemical reaction but it is actually a physical reaction meaning that all the elements are all there.

Coca Cola is a drink that everyone adores, but the well-known truth is that it can certainly damage your health. There are numerous experiments with Coca Cola that can be found on Youtube and leave people shocked.

The costing technique followed by the Coca-cola Company is Process Costing which is one of the forms of Absorption Costing.

The Coca-Cola Company is the world's largest beverage company, refreshing consumers with more than 500 sparkling and still brands.

According to The Coca-Cola Company's 2005 Annual Report, the firm sells beverage products in more than 200 countries. The report further states that of the more than 50 billion beverage servings of all types consumed worldwide, daily, beverages bearing the trademarks owned by or licensed to Coca-Cola account for approximately 1.5 billion (the latest figure in 2010 shows that now they serve 1.6 billion drinks every day. Of these, beverages bearing the trademark "Coca-Cola" or "Coke" accounted for approximately 78% of the company's total gallon sales.
