Myth (brief description) THE GALLON CHALLENGE Our myth is to see if a person can drink a gallon of milk in an hour or less.

Research (write down the words and defintions you were responsible for finding as well as the questions and answers) Acid is any compound that reacts with a base to form a salt. A base is a chemical that has more protons than electrons (on the pH scale). PH is decribing if something is a base, an acid, or a nutural. The pH in milk is around 7 (6.4-7.6). The pH in your stamach is between 1.5 and 2 which is very acidic.The pH of stomach acid is 1.5-2. There is a pH scale, 0 on the scale is on the acid side, 14 is a base (if you have too much of acid or too base, it is very harmful) and 7 is neutral. When an acid and a base come in contact with each other, they become a salt. A chemical reactionis a precess that leads to the transportation of one set of chemical substances to another.A product is a substance that is formed as a result to a chemical reaction. The average human stomach can hold up to 32 ounces.

Water is a pure liquid and milk is a suspension in water.If you mix water and acid it boils and if it gets on you it could leave a burn.The unsaturated fat of milk turns into saturated when it's mixed with milk.Stomach acid takes foods and sorts them out to where they need to go. It also prevents viruses, fungi, and bacteria from coming into the body and hurting you. (HIC)The milk will turn into a solid (or it curdles) which makes you not want to drink more because a solid takes more room then a liquid. A reaction is something that will react to something else. The reason they say people can't drink a gallon of milk in a hour is because you don't have enough lactase in your body to break down the lactose in the milk which causes you to throw up and because the typical stomach can't even hold a gallon. It matters on what percent of milk it is because it matters on the amount of lactoce in the milk and the amount of fat and sugar. If you have lactose free milk then you are less likely to throw up. then also with the least amount of fat in the milk you are able to hold more in your stomach.

**__ Small Scale Procedure __**

Can an average person hold a gallon of liquid?

Dependant variable: Can their stomach hold a gallon of liquid?

Independent variable: The size of the person drinking the water.

Constant: The type of liquid, the temperature of the liquid, and the amount of liquid.

Hypothesis: We think that all three testers will be able to drink a gallon of milk in one hour because water does not have lactose so we think their stomachs can hold it. Supplies: 3 testers, 3 gallons of cold tap water, 3 cups, 1 timer, 3 vomit stations, and 1 tape measure.


 * 1) Gather supplies.
 * 2) Station the 3 testers around a table.
 * 3) Set one gallon of cold tap water, one cup, and one vomit station for each person around the table.
 * 4) Measure and record each person’s height and abdomen around the belly button.
 * 5) Set timer for one hour
 * 6) Start the timer and have the testers begin.
 * 7) Check in on each tester at 15 min., 30 min., 45 min., and 1 hour. Ask them questions and record their answers. Observe their actions.
 * 8) Have them stop when the timer goes off.
 * 9) Measure the remaining water and record the amount.
 * 10) Question the testers and record their answers.
 * 11) Clean up.

// __If they vomit or use the restroom their experiment is over .__ //

__**SMALL SCALE TEST CONCLUSION:**__ We learned that the average human stomach of a person our age CANNOT hold one gallon of water.

During our experiment, we had three testers. Each had the same amount of water (one gallon) to start with, but none of them finished it. One of the three testers vomited with four cups left. Another tester had to use the bathroom with 11 cups left. The last tester was able to make it to the end, but they still had seven cups of water left. It is not possible for the human stomach to hold one gallon of water.

We believe that our stomachs could not hold the water because the average ADULT human stomach can only hold four cups at a time before digesting it. Considering that, it has to be nearly impossible to do so with an adolescent's stomach because it is not as large.

How much milk can the three tester hold in their stomachs. DEPENDENT VARIABLE: How much can their stomachs hold? INDEPENDENT VARIABLE: The size of the person/tester. CONSTANT VARIABLE(S): The type of liquid, the amount of liquid, the liquid temperature. HYPOTHESIS: We don't think that the testers can hold a gallon of 1% milk, because the average adult stomach can only hold 4 cups and they couldn't even hold a gallon of water. SUPPLIES: 3 testers, 3 gallons of milk, 3 cups, timer, vomit stations (3 trash cans), measuring tape.
 * __LARGE SCALE TEST PROCEDURE__**

10. Clean up the experiment. **__ Large Scale Conclusion __** A person cannot drink a gallon of milk in a hour or less. The experiment had 3 testers and the same amount of milk for each tester (one gallon) we sat them around 2 tables, and had them drink a gallon of milk for 1 hour. One tester peed after 5 2/3 cups of milk. Another peed after drinking 5 1/3 cups of milk. Another made it to the end of the hour but only drank 2 cups. An average adult stomach can only hold four cups at a time until digesting it, so we don’t think we would be able to hold that much milk either.
 * 1) Gather your supplies.
 * 2) Station the 3 testers around three different tables (sitting or standing).
 * 3) Set out 1 gallon of milk, 1 cup, and 1 vomit station out in front of each tester.
 * 4) Measure and record each person's height and the distance around their abdomen (roughly over their belly button) and record the measurements.
 * 5) Set the timer for 1 hour.
 * 6) Start the timer and have the testers begin.
 * 7) Check in on each tester at the 15, 30, and 45 minute mark. Ask them questions about their situation in the experiment and record their answers. Observe their actions and record as well.
 * 8) Have them stop when the timer goes off.
 * 9) Measure the remaining liquid in each of the testers' containers/cups/cartons.
 * If a tester vomits, uses the bathroom, or wastes any of the milk, THEY ARE DISQUALIFIED and their information will be left as is.**

Our myth was to see if a person can hold a gallon of milk in an hour or less, and we found out that this myth was confirmed. A person can not hold a gallon of milk in their stomach because you can only hold 4 cups of milk in your stomach before digesting it. A gallon is **__four times__** that amount so your stomach can not hold that much. Also, the lactase in your stomach mixes with the lactose from the milk making you feel like you need to throw up.
