  1. For each cup, put one straw in the hole. Put the larger diameter straw in the cup with the larger hole. Put the smaller diameter straw in the cup with the smaller hole. Make sure the hole is not squeezing the straw and narrowing it.
  
  2. Use play dough, clay, or silly putty to seal the hole inside the cup and around the straw so that water cannot leak out of the hole. Why do you not want water to leak out the holes? How might that change your experiment?
  If the water leaks out, the rate of water flowing will not be accurate.
  
  3. Make sure the straws are pointing down so that the water can flow out.
  
  4. Do you think the straws will have the same or different flow rates? Why?
  They will have different flow rates because the size of them is different.
  
  5. Put both cups in a pan or basin. Quickly fill both cups with water. Fill them to the same level. Either fill the cups at the same time, or fill the cup with the smaller diameter straw first. Watch carefully to see if water stops flowing from the two cups at the same or different times.
  
  6. If you have enough water, refill the cups and watch again. Do this several times to see if the results are always the same.
  
  7. Does water stop flowing out of the two cups at the same or different times? What does this tell you about the flow rate? Is the flow rate of a straw with a large diameter the same or different from the flow rate of a straw with a small diameter?
  Water stops flowing out at different times. It tells me that the flow rates of the water flowing out the two cups are different. The flow rate of the larger straw is higher than that of the smaller straw.
  
  8. Based on your experiment what do you think happens to the flow rate of blood during coronary heart disease? Hint: Remember that people with coronary heart disease have arteries with smaller diameters.
  When a person has coronary heart disease, his arteries, which transports oxygen-rich blood throughout the body, will be smaller. The blood will be transported in a slower rate, thus his heart rate will be higher than normal people.

  2. If the water leak out from the cup then the experiment is going to be hard for us to get the actual result of the experiment. Also it is going to be hard for us to do see weather or not, which tube will leak out the water more faster.
  4.I don't think the straws will have the different flow rate because the one with the larger whole has more space for the water to leak out because it has more spaces.
  7.The water stopped flowing at different times and this tells me that the rate of the water in the cup with larger tube makes the water leak out more faster than the smaller tube because it has more spaces.
  8. The blood will be hard to flow through a person's body which will lead to death.

  2) Because the water will leak faster and there is another hole.
  
  4) They will have different flow rates because the diameter of the straw is different so there will be different flow rates.
  
  7) More water was leaking from the straw with the larger diameter as compared to the small diameter straw.
  
  
  8) The blood flow will be slow.

  2. Use play dough, clay, or silly putty to seal the hole inside the cup and around the straw so that water cannot leak out of the hole. Why do you not want water to leak out the holes? How might that change your experiment?
  You don't want any water to leak out the holes because the blood only goes through blood vessel. Also if the water leak out the hole, the amount of water that's falling out will not be accurate.
  
  4. Do you think the straws will have the same or different flow rates? Why?
  Yes because the size of the straws are different.
  
  
  7. Does water stop flowing out of the two cups at the same or different times? What does this tell you about the flow rate? Is the flow rate of a straw with a large diameter the same or different from the flow rate of a straw with a small diameter?
  The water stops flowing out of the two cups at different times. This tells me about the flow rate that the bigger straw will release water much faster than the smaller one, because it has a bigger space for the water to flow through.

  1. Why do you not want the water to leak out of the holes? How might that change your experiment?
  That changes the experiment by decreasing the percentage of accuracy not letting the person who conducted the experiment able to get accurate measurements.
  
  2. Do you think the straws will have the same or different flow rates? Why?
  Yes, I think that they will flow at different rates because they have different sizes so they will have different amounts of liquid that is able to flow through them.
  
  3. Does water stop flowing out of the two cups at the same or different times? What does this tell you about the flow rate? Is the flow rate of a straw with a large diameter the same or different from the flow rate of a straw with a small diameter?
  Since they are different sizes, they stop at different times. This tells me that they also have different flow rates as well. The straw with the larger diameter can disseminate larger amounts of liquid that the straw with the shorter diameter.
  
  4. Based on your experiment, what do you think happens to the flow rate of blood during coronary heart disease?
  Therefore, from this experiment you could conclude that if you have shorter vessel diameters, the less blood that can go through. This can eventually result in heart attacks and other detrimental states.

  2. You don't want water to come out of the holes because it could change the flow of the water. You want the speed of the water fall to be different from each other without any fault. This could affect the accuracy of your experiment.
  
  4. The straws will have a different flow rate because the size is different for each straw. The one with a bigger hole will have more liquid flowing at one time, while the smaller one will have less liquid.
  
  7. Water stops flowing out of the cup at different times. The one with the larger straw lost liquid faster and the smaller one lost liquid slower. The flow rate will be different even though there is a different amount of liquid.
  
  8. People with coronary heart diseases will have a slower flow of blood compared to those without diseases. Blood flows slower, making all the other organs move slower.

  2.Use play dough, clay, or silly putty to seal the hole inside the cup and around the straw so that water cannot leak out of the hole. Why do you not want water to leak out the holes? How might that change your experiment?
  
  Because like if the water is not blocked then the test will not be right and also the answers will not come out currectly.
  
  4. Do you think the straws will have the same or different flow rates? Why?
  
  Yes I do think that straws will have the same flow rates because if it is different then you can't carry out the experiment.
  
  7. Does water stop flowing out of the two cups at the same or different times? What does this tell you about the flow rate? Is the flow rate of a straw with a large diameter the same or different from the flow rate of a straw with a small diameter?
  
  The diameter is different because the tube's size is different.

  2. If they are leaking' there would be large difference when it is block the hole.
  
  4.nope, because the flow rate will get different by the size of the straw, such as Vein and other things.
  
  7.There is large difference between the large size and small size, large size can flow the blood faster and more, but the narrow straw flow the blood slower.
