As part of the requirements in Pre-Health Physics, students are to complete a Cross-curricular Project for the term. The objectives of the project are: a) to connect Physics with other courses in the program, such as Biology, Chemistry and Math, and b) to relate Physics to everyday phenomena with focus on the human body, the health sciences and/or health-care applications.
This project will address the following course learning outcomes (CLO) and essential employability skills (EES) found in your course outline.
Type in your answers in the space provided after each question. You are allowed to insert any images or photos to support or accompany your answers. Make sure that the image is clear to the viewer and of a reasonable size by cropping, reducing or enlarging it.
Cite references and provide links for all non-original resources used (i.e., things you did not create yourself) including text, images and videos. APA citations are recommended but not required. Also, acknowledge any specialists (doctors, nurses, professors, etc.) you may have interviewed to complete this project.
Mary is a student enrolled in the PHS program. She is her mid-20s and has a young son, Andrew. Mary takes Durham Transit bus 915 every morning to take her to school for her early 8 am class. From the campus bus loop, she listens to her favourite music on her phone and enjoys the beautiful sights of the campus while walking towards the building. She then rides the elevator to the 4th floor to get to her classroom.
1) What is Mary’s rate of walking if she covers 10.7 m in 3.0 s while walking from the parking lot to the building? Apply the rules on significant figures in reporting your answer.
2) Mary’s mass is found to be 55.0 kg. While walking, what is Mary’s linear momentum? How much mechanical kinetic energy does Mary have?
3) The 4th floor is 11.5 m above the ground. How much gravitational potential energy has Mary gained going to the 4th floor?
4) Will Mary have more potential energy, less potential energy, or the same potential energy, if she walked up the stairs instead of riding the elevator? Explain your answer.
5) List all forms of energy that Mary can observe starting from the bus loop, while walking towards the building, riding the elevator, and finally sitting in her classroom.
Mary is equally interested in the three science courses she’s taking in the PHS program, namely, Biology, Chemistry and Physics. While studying the respiratory and circulatory systems, Mary is also studying pressure and fluids. Help Mary explore and relate those lessons.
1) Define the following terms: density and pressure.
2) It is found that on the average 100 ̅ ml of blood weighs 106 g. What is the density of blood in kg/m3?
3) Mary went to the Wellness Centre to take her blood pressure. The blood pressure reading she got was 145/92. What do the two numbers 145 and 92 stand for? What unit of pressure does 145/92 have?
4) What ranges are considered to be normal, below normal and above normal blood pressure? Under what range is 145/92?
5) What usual advice are given to a person with such blood pressure reading?
Lately, Mary has been experiencing nausea and vomiting in the morning and other typical signs of pregnancy. Upon consultation with her obstetrician, an ultrasound was ordered to assess her pregnancy.
1) Is ultrasound a mechanical wave or an electromagnetic wave? Explain your answer.
2) What frequency range of sound is audible to humans? Express you answer in hertz, Hz.
3) Differentiate infrasound from ultrasound.
4) Aside from using ultrasound to assess Mary’s pregnancy, what are other medical uses of ultrasound? List at least 4 uses.
5) If the result of the ultrasound indicates that Mary is pregnant, what are the possible medical advice her obstetrician would give her?
Mary has been doing a lot of readings lately. However, she finds her vision to be a little blurry and has difficulty focusing on objects that are up close. She decided to go for an eye check up. After a thorough test, she was prescribed a pair of eyeglasses.
1) Eyeglasses are actually thin lenses mounted on frames. What are thin lenses?
2) What are the different types of thin lenses?
3) Define the following conditions related to eyesight: myopia, hyperopia and astigmatism.
4) What type of lenses should be used to correct each of the three conditions mentioned above?
5) From Mary’s description of her eye problem, which of the three conditions (myopia, hyperopia and astigmatism) is she most likely suffering from? What type of glasses do you think were prescribed to her?
It is recommended that every home in Ontario should be tested for radon, no matter where it is located. Aware of this, Mary recently hired a licensed radon professional to check her home for potential radon gas. Luckily, her house passed the test. No levels of radon were found.
1) What is radon? Describe its chemical properties.
2) What level of radon gas is considered to be dangerous for humans?
3) How can radon gas find its way into Mary’s home?
4) What are the known health effects for long exposure to radon?
5) In general, describe biological effects of exposure to various types of radiation.
BONUS QUESTION (OPTIONAL):
Describe any concept we study in PH Physics and relate it to health science or healthcare. In other words, describe a Physics concept and its application in health science or healthcare.
