After completing the experiment, I accept and support my hypothesis which was that 3 Mentos would create the tallest soda geyser. The average height of 1 Mento was 24.7 inches, 2 Mentos was 51.7 inches, and 3 Mentos created the tallest geyser averaging at 58.7 inches. It is clear that the 3 mento geyser is the tallest geyser due to the greater amount of Mentos. In this experiment there were many sources of error. The first one was that the experiment was being done on a uneven surfaces causing the geysers to shoot left or right instead of straight up causing the geysers to not reach their true height. Another error was that when dropping in the Mentos, they were not evenly spaced times causing different reactions and different heights. An additional

Some colas will explode higher or lower because of the amounts of caffeine, sodium, or sugar. Also how fast the mentos fall into the bottle can affect the height of the geysers. It has been proven that there is a difference
There are several sources of error to this experiment due to random and systematic errors. The only source of random error was the measurement that we took through the graduated cylinder which was only accurate to the nearest 1%. We took the largest error from this one percent, which was +/- 3. The largest relative error this yielded was only 3%, so this did not affect how precise this experiment was too much. We can still make this more precise by making the masses of the water larger. For example if we started the masses at 300mL and went up by 50mL, the largest error this would yield would be 2% due to the largest error being +/- 5. This would cause smaller errors in the amount of water.
The purpose of the lab was to mimic the way Mendeleev placed the elements on the periodic table. Mendeleev was a Russian chemist who produced the first orderly periodic table. Frist, the way the periodic table has been classed alongside the atomic sum and the elements with related properties. Second, the objectives are observeing the physical states of common elements, and the progression of the periodic table, lastly speculate by determining the unknown elements established on the observed progression. As a group we tried to find out where the unknown elements should be placed. Finnly, the information that was given to help us with our process was the state, density, hardness, conductivity, melting point, and color.
The diet coke and Mentos experiment has been a favorite of amateur scientists, but how does it work? There have been debates, and scientists have concluded that the diet coke and Mentos is a physical reaction, called nucleation. Nucleation sites are areas that have high surface with low volume. Such places can be your fingerprint, scratches on glass, specks of dust, or even Mentos candy (Eepy Bird). Mentos candies have a pitted surface that’s rough when looked at through a microscope, therefore creating a wonderful place for nucleation to occur. Water molecules like to be next to other water molecules, so if you drop something into the soda, like Mentos, it acts as a site for growth of bubbles. Mentos have a high
A rougher candy surface such as, Mentos, means there are more places for bubbles to grow, or more nucleation sites. (brilliant.org) Surfactants are compounds that lower the surface tension between two liquids. (brilliant.org) Dropping Mentos in Coke is an example of a surfactant. The eruptions happen due to nucleation where the Carbon Dioxide in the soda is drawn to the Mentos. (eepybird.com) The pressure of the bottle is trapping the CO2 inside. The CO2 in the soda reacts to the sugar on the Mentos.
Abstract: This experiment introduced the student to lab techniques and measurements. It started with measuring length. An example of this would be the length of a nickel, which is 2cm. The next part of the experiment was measuring temperature. I found that water boils around 95ºC at 6600ft. Ice also has a significant effect on the temperature of water from the tap. Ice dropped the temperature about 15ºC. Volumetric measurements were the basis of the 3rd part of the experiment. It was displayed during this experiment that a pipet holds about 4mL and that there are approximately 27 drops/mL from a short stem pipet. Part 4 introduced the student to measuring
Alka-seltzer Lab Report Statement of the Problem: The question of this lab was to find the optimum amount of Alka-Seltzer and water to achieve the highest launch possible. As Alka-Seltzer can dissolve in H2O and release CO2g (carbon dioxide gas), the gas is trapped inside the container and starts to gain pressure. This is the combination produces Sodium Bicarbonate which releases CO2g and other products. When the pressure in the container reaches maximum pressure, the lid will pop off releasing the gas and making it fly upwards.
When four paper clips were added to the cup, the water had not even begun to show signs of spilling. By the end of the experiment, the cup of water was able to hold 120 paperclips before the water ran over. As the 119th paperclip was added, we noticed a somewhat large “half bubble” on the surface of the cup. This ‘bubble’ was caused by 3 factors known
The volume of a small test tube and a thin-stemmed pipet were determined in this section of the lab. Water was poured into a small test tube until the water reached the very top edge of the test tube. The test tube was then emptied into a plastic 25 mL graduated cylinder and volume was measured and recorded into data table 3. A think-stemmed pipet was completely filled with water. Drops were carefully counted and emptied into the empty plastic 25 mL graduated cylinder until the water level reached 1 mL. The number of drops in 1 mL was recorded into data table 3. The thin-stemmed pipet had a total volume of 4 mL and that was also recorded into data table 3.
If we have waited a couple of more minutes for the carbonation, the balloons could of have been bigger and we would have had more accurate data. Some challenges we faced in our project was that some of the balloons popped while during the experiment and we figured out that they popped because of the amount of salt. We could have improved on the amount of salt that was poured into the soda. We should have added less salt to the balloon because that would have stopped the balloons from popping. The next step would have been to put less salt so the soda does not elevate to the top and fill up and pop the balloons.
“Those that touched the boiling cauldron will have countless burned fingertips. We shall sling it mightily against the wall and watch waves of truth release from the steam—and our souls will feel redemption. As for those who hope to cover their sin—the lid remains. Take it to breast and shield thy evil heart; for in time we shall know your part!”

In this experiment, The purpose of this experiment is to investigate the measurement of the actual volume contents of volumetric glassware. In the beginning of the experiment, the volumetric glassware should be clean and dry before used. The volumetric glassware, measuring cylinder and pipette should be handled with care and all the precautions were be taken during the experiment was held. This was to ensure to avoid any errors such as parallax error especially while reading water meniscus. This experiment must be repeated three times or more and take the average reading to get more
As previously stated, knowledge on this particular subject has been limited. Ever since Gause’s experiment, not many other scientists have attempted it until recently. As a class, the experiment was a way to observe competition and better interpret the results gathered
