how fast does it flow?

benchmark covered: benchmark sc.c.1.3.1: the students knows that the motion of an object can be described by its position, direction of motion, and speed. purpose: in this experiment, you will figure out the relationship between the amount of water in the bottle and how fast it flows from one bottle to the other. problem statement: how fast does water flow from one bottle to the other during a vortex? potential hypothesis(es): •if the liquids are spinning more quickly creating a big vortex, then the amount of ml/s will be more efficient. materials: • two clear soda bottles • tornado tube • stopwatch • water • chocolate milk • salt water • vegetable oil • measuring cup • funnel

procedures: 1. using the measuring cup, fill one of the bottles with 4 ounces of water. 2. connect the other bottle using the tornado tube to the bottle you were currently filling with water. 3. turn the connected bottles upside down, swirl them and put them on a flat surface with the empty bottle at the bottom. ask a partner to time how long it takes for the water to flow from the top bottle to the empty bottle at the bottom with a stopwatch. 4. practice step 3 several times to make sure that you and your partner can perform your jobs in the same way every time. if a vortex does not form when you swirl the bottles, try again with more swirling action. 5. the person with the stopwatch should stop the time when all of the water from the top bottle has traveled to the bottom bottle. 6. repeat the experiment several times using different amounts of water. 7. create a data table listing the amount of time in seconds that it took to empty the top bottle. several trials are recommended so that you can average the times to get more accurate reading. variables: • there were three variables in this experiment. they were the type of liquids used, the amount of water that was added to the bottles, and how fast was the flow of water per second. i was in control of the types of liquids used and the amount of water that was added. the flow of water per second was my dependent variable. results: • my hypothesis was correct, because in some areas of the experiment putting more amount of liquid in the bottles would increase and decrease depending how much were the bottles swirled to create an even larger vortex. conclusion: as i added more water the water flowed faster, in most occasions. gravity affects the water flowing from one tube to the other, because gravity is helping push the water down. gravity has more of an impact with more water, because during the experiment as i and some of my partners added more water we have seen proof that the amount of ml/s increased. water had the fastest flow of rate, because it doesn’t have any ingredient that makes it so dense. to ensure accurate results in this experiment i could of repeated the entire experiment again or taken notes.
