Aim To determine whether orange juice has more electrolytes than well-known sport drinks Background Information In my experiment, I am testing the conductance of different drinks. This relates to the amount of electrolytes they have within them. The drinks that I am testing are Maximus, PowerAde, Orange Juice, distilled water and Tap water. I choose these drinks because there has been much discussion whether sports drinks actually affect the performance of a normal person, relating to the amount of electrolytes in the substance. The body loses electrolytes during exercise through sweat, these sports drinks are meant to replace these lost electrolytes to allow the person doing the exercise to perform at their best. Electrolytes are charged …show more content…

I would predict that distilled water would get next to nothing in conductivity due to it being completely pure water. Pure water as absolutely nothing in it other than H20. This means that distilled water would note have any minerals or chemicals that may be able to conduct electricity unlike tap water, which does have these minerals and chemicals. Tap water obtains minerals to safe from diseases and bad infections to other people, this is a necessary action for other people`s safety. Hypothesis My hypothesis for this experiment was that the sports drinks would be the substance with more electrolytes, in particular the Maximus sports drink as other people who have conducted experiments of sports drink have found Maximus to have more electrolytes to other sport drink brands such as PowerAde Equipment The main/ essential things are: • Digital multimeter/ ammeter • Alligator clip leads • Copper wire, bare, 24-gauge (1.5 meters) • 9 V …show more content…

Using the scissors, cut a 5cm piece of a straw and wrap two separate lines of copper wire around the piece of straw at both ends, make sure that there is at least 5cm remaining of the copper wire after it is wrapped around the straw (like in the image to the right) 2. Begin to construct the circuit: Constructing the Circuit: 1. Gather the multimeter, wires, alligator clips, copper straw (above), 9V battery and 9V battery clip 2. Connect the 9V battery to the 9V battery clip and connect the negative wire of the battery clip to a wire, then connect this wire to the copper straw using the alligator clips on the end of the wire 3. Attach the other alligator clip to the other side of the copper straw which will the connect back to the input of the multimeter through a wire 4. Finish off the circuit by connecting the output of the multimeter to the positive of the battery clip (if this is completely correctly, it should look like the image

  • Caffeine Free Soda Experiment

    1522 Words  | 4 Pages

    Per the hypothesis, most of the results in the lab are in accordance with the expected results. It was expected that the subjects drinking caffeine, diet caffeine free soda, and 16 ml/Kg of water would have a higher rate of production than the control group drinking 7.5 ml/Kg of water due to less water being reabsorbed. Results showed an increase in rate of production, most notably in subjects drinking diet caffeine free soda but seemed to decrease towards the end. For the rest of the subjects, the data shows a gradual rise over time with every subject (besides caffeine free) having a higher rate of production than the control group. The subjects drinking caffeine free soda were the only ones to record a lower rate of production than the control group. This could be due to an increase in glucose reabsorption causing water to follow back into the blood stream. The lack of caffeine does not hinder ADH secretion, which will cause an increased permeability to water in the collecting

  • Ad Analysis Of Gatorade

    1176 Words  | 3 Pages

    For more than 50 years, Gatorade, America’s premier sports beverage has proven that their product is vital when it comes to hydration because it effectively replaces the fluids and electrolytes lost through sweat and replenishes the large amounts of carbohydrates that players’ bodies use for energy. Since the dawn of the media age, Gatorade has been on the forefront of promoting their product through advertisements, the main linkage between business and consumers in any field or market. One of the main reasons the company has retained this respectable dominance for the entirety of the twenty-first century is their ability to attract and retain their audience through their popular commercials. These virtual ads from Gatorade almost always feature

    The data for my experiment showed that as time went by the heart rate increase followed by a major decrease known as a crash. A crash occurs when your heart rate increases so fast all at once that when the caffeine’s effect wares off the heart rate drops rapidly. Energy Drinks are known to give you energy, but part of the agreement that comes with consuming these types of drinks is being ready for the consequence. Some consequences are more severe than others. My hypothesis was proven to be correct. Your heart rate does increase over time due to the amount of caffeine the energy drink

  • The Process Of Building A Trebuchet

    1107 Words  | 3 Pages

    The simple steps were laying out your prototype and seeing where the items go. You must then build your trebuchet how instructed. You can use rubber bands to reinforce the corners to build a triangle. After you make one triangle use the measurements to construct an equilateral triangle. Then use three dowels and six rubber bands to create a base that connects the two triangles. On each side connect one craft stick to support the dowles. Use a rubber band to connect the wooden skewer along the dowel until it is four inches off the end of the dowel. Unfold a paper clip until it is straight and use tape and attach to the end of the long arm and make sure one inch is of the wire expands past the dowel and slightly bend upwards. Then use the straw and cut two three inch segments and place on the ends of the skewer. Then rest the skewer in the cradle of the apex of the triangle. Place a piece of cardboard on top of the dowels to create a platform. Cut the corners off of the mesh fabric and cut your string into two ten inch segments. Tie an end of the string to the throwing arm of the trebuchet one inch from the end of the string. Take a resealable bag and gather your counterweight(s) and hook a paper clip through each arm of the binder clip and thread the end of each paper clip through the holes in the plastic bag. Clip the counterweight(s) to the throwing

  • Comparison of the Densities of Coke and Diet Coke

    684 Words  | 2 Pages

    Regarding the densities of Coke and Diet Coke, I believed that the density of coke would be greater than the density of Diet Coke. Because the content of Coke contains more sugar than Diet Coke, it would contain more mass and since density is mass dependent, Coke would be denser than Diet Coke. From the results of the experiment, there was a slight difference between the densities of Coke and Diet Coke. The measurements obtained from the pipette and the graduated cylinder demonstrated that Coke is denser than Diet Coke while Diet Coke was shown to be denser than Coke using the burette. With the pipette, the average density of Coke is 1.02 and the average density of Diet Coke is 0.99. With the graduated cylinder, the average density is 0.976968 and the average density of Diet Coke is 0.95. With the burette, the average density of Coke is 0.99 and the average density of Diet Coke is 1.0. Among the three instruments, the most precise was the graduated cylinder and the most accurate was the volumetric pipette. Since density is defined as mass/volume, changing the volume of Coke or Diet Coke would have changed.

  • Does Gatorade Enhance Athletic Performance

    ...ble in a Gatorade bottle but these are the most important ones. The most chemistry that is present in sports drinks and in this case, Gatorade, is seen through the electrolytes. In a nutshell electrolytes are substances that are soluble in water and after being completely dissolved, they give ions. Our body consists of Cation and Anion electrolytes which are nutritionally referred to as Macrominerals. As stated before the balance level of electrolytes is every crucial for the human body, and if imbalanced the person can have serious and life threatening issues. But the only way to restore our electrolytes level is by consuming these sports drinks, so this is the main reason as for why even though the sports drinks have some negative aspects to them they are one of the cheapest and easiest ways a person can get the required electrolytes for their body.

  • Critique of an article from the Journal of Applied Physiology

    1108 Words  | 3 Pages

    In 2002, a group of Australian researchers published a paper entitled the "Effect of different protocols of caffeine intake on metabolism and endurance performance". Caffeine use during sporting events has become much more popular and has widely studied. The purpose of the research was to examine the work increasing (ergogenic) effects of differing regiments of caffeine on metabolism and performance while simulating the typical nutritional preparation an athlete would do for a race. The study also sought to examine the effect of timing of caffeine intake, comparing results when caffeine was given before an event (precaf) to results from caffeine given during an event (durcaf). In addition, the researchers wanted to understand the practice of endurance athletes drinking defizzed Coca-Cola towards the end of a race. It was widely observed that many triathletes and marathoners feel they derive a boost from consuming Coca-Cola in the final stages of an event as a replacement to sports drinks.

  • Gatorade vs. Water

    1525 Words  | 4 Pages

    Early summer, about forty-eight years ago in 1965, University of Florida assistant football coach, Dwayne Douglas, sat down and wondered why so many of his players were suffering from heat strokes and heat related illnesses during games or practice. So, he went to the university physicians and asked them to determine why this was happening. Not long after it was discovered that two key factors were causing the Florida Gator players to suffer from these conditions: the fluids and electrolytes the players were losing during the events were not being put back into the body, and the massive amounts of carbohydrates the players' bodies used for energy were not being replenished. So, he decided to create Gatorade. There are plenty of Gurus out there who will sit and tell you that water is natural and it’s the best thing you could ever put into your body, but let’s get real I’ll take scientifically proven research over someone’s “word” any day.

    Overall I think I carried out the experiment in a precise way and I took my time trying to make all my measurements as accurate as possible so that my data is reliable. Next time I will do more tests instead of just 3 so I have more results and so I could get a more accurate average. I will also do the experiment with more fruit juices to see if there are other fruits with a higher content of vitamin C. I will do an experiment to see if there is a difference in Vitamin C levels between fresh juice and store bought juice. I can also test different brands of juice to see if they have different levels of vitamin C.

  • Citrus Juice Lab Report

    The freshly squeezed citrus juices of Lemon,lime and orange were analysed through titration over the period of 2 weeks. Initially the lime juice was found to be slightly more acidic than the other juices followed by lemon juice and then orange juice since it is known that usually lime is more acidic than lemon and orange. It was hypothesised that the acidity of each juice will increase or decrease after the period of two weeks depending upon the sugar content of that citrus fruit that the juice is extracted from. The acidity of the juice with the highest sugar level will gradually increase over the period of time since sugar contribute to the the fermentation of the citrus juice to lactic acid. The hypothesis was shown to be correct;however
