I learned that muscles are important to human and if there is even 1 mistake or been wrong with that system you can get bad illnesses. Also I learned that bones are important to make the muscles develop.

My favorite and most interesting fact I have learned about the circulatory system is the nephron system (according to the site above) because this system is really small that you can't even see and this has the important role in your body with millions of filtering structure so this made me really interesting by the most in the circulatory system.

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.

this strand in the rubric means that after the experiment you need to know the patterns of the reactivities of the metals (1~5) and it means to that you need to evaluate on rather the data is reliable or not according to the scientific reasoning.

Heart rate is basically about the amount of heart beat in your body and pulse rate is the rate from your pulse and doctors uses this a lot to check your health.

When you exercise the resting heart rate become the active heart rate and it keep increases by time and the organs and the respiratory systems starts to be tired and use more energy and you will be thirsty or hungry in the end.

The most important product is lungs because lungs are the last process of the respiration systems and this is the part who gets the fresh air and and clean the waste and carbon if people don't have lungs then people can't consume fresh air and can't clean the air to the fresh air and the carbon will remain. Also people can't even breath if there are no lungs so that is the reason why lungs are important for people to breath as products.

Breathing is the thing people needs to do in every day life and this is just making the air go through your respiration system and the respiration system are the organ you need to actually make the human or animal to breath properly and make the body have fresh air and let the wastes and carbon out of the body.
