Labs​ ​that​ ​are​ ​judged​ ​to​ ​be​ ​plagiarized​ ​will​ ​receive​ ​no​ ​credit. Part​ ​1—Height​ ​:​ ​Weight​ ​Ratio a. Fill​ ​in​ ​the​ ​following​ ​chart: Height​ ​(in​ ​cm) Weight​ ​(in​ ​kg)   ​165.10      ​73.93556 centimeters Kilograms​ ​(kg) b. Height​ ​÷​ ​Weight​ ​(​Actual) Height​ ​÷​ ​Weight​ ​(​Expected)      2.23303​ ​cm/kg 4​ ​cm/kg Answer​ ​the​ ​following​ ​questions: Is​ ​height​ ​in​ ​centimeters​ ​equal​ ​to​ ​four​ ​times​ ​weight​ ​in​ ​kilograms?​ ​Did​ ​you​ ​support​ ​or​ ​refute​ ​the​ ​hypothesis? No,​ ​my​ ​weight​ ​which​ ​was​ ​73.93556​ ​(kg)​ ​and​ ​when​ ​multiplied​ ​by​ ​4​ ​equalled​ ​295.74224​ ​which​ ​was​ ​nowhere​ ​equal​ ​to​ ​what my​ ​height​ ​in​ ​centimeters​ ​is​ ​which​ ​is​ ​165.10.​ ​My​ ​hypothesis​ ​was​ ​that​ ​multiplying​ ​by​ ​4​ ​would​ ​put​ ​the​ ​weight​ ​result​ ​so​ ​high that​ ​it​ ​would​ ​not​ ​be​ ​equal​ ​which​ ​resulted​ ​to​ ​be​ ​correct. Part​ ​2—Arm​ ​Length​ ​:​ ​Relationship​ ​of​ ​Height​ ​to​ ​Arm​ ​Length a. Fill​ ​in​ ​the​ ​following​ ​chart: Height (cm) You:165. 10 Someon e else;190. 50 b.

Why​ ​is​ ​it​ ​important,​ ​in​ ​scientific​ ​terms,​ ​to​ ​have​ ​measurements​ ​like​ ​these​ ​standardized?      I​ ​just​ ​measured​ ​from​ ​my​ ​shoulder​ ​to​ ​my​ ​elbow​ ​then​ ​my​ ​elbow​ ​to​ ​my​ ​wrist​ ​letting​ ​my​ ​arm​ ​bend.​ ​There​ ​are​ ​several different​ ​ways​ ​arms​ ​are​ ​measured​ ​the​ ​standard​ ​way​ ​is​ ​to​ ​spread​ ​your​ ​arms​ ​out.​ ​This​ ​information​ ​teaches​ ​science​ ​about the​ ​human​ ​body. Did​ ​you​ ​support​ ​or​ ​refute​ ​the​ ​hypothesis​ ​that​ ​the​ ​relationship​ ​of​ ​arm​ ​length​ ​to​ ​height​ ​is​ ​arm​ ​length​ ​is​ ​.4​ ​(​ ​+​ ​or​ ​,05)​ ​times​ ​height​ ​in​ ​centimeters?​ ​ ​Do​ ​you​ ​think​ ​any​ ​of​ ​your​ ​online​ ​classmates​ ​found​ ​the​ ​alternate​ ​result?​ ​Why​ ​or why​ ​not?      I​ ​figured​ ​the​ ​outcome​ ​would​ ​be​ ​smaller​ ​than​ ​the​ ​expected.​ ​I​ ​believe​ ​everyone​ ​had​ ​unique​ ​results​ ​even​ ​at​ ​different heights​ ​because​ ​measuring​ ​arms​ ​from​ ​home​ ​might​ ​will​ ​result​ ​in​ ​so​ ​many​ ​different​ ​numbers. Part​ ​3—Hand​ ​Temperature What​ ​factors​ ​do​ ​you​ ​think​ ​might​ ​affect​ ​a​ ​person’s​ ​hand​ ​temperature?      Blood​ ​flow​ ​affects​ ​body​ ​or​ ​hand​ ​temperature,​ ​and​ ​so​ ​movement​ ​and​ ​outside(clothing)​ ​or​ ​environmental(weather) influences​ ​play​ ​a​ ​role. What​ ​is​ ​your​ ​hypothesis​ ​about​ ​hand​ ​temperature?      Hand​ ​temperature​ ​can​ ​change​ ​depending​ ​on​ ​things​ ​like​ ​temperature,​ ​movement,​ ​and​ ​our​ ​body​ ​dynamics. Answer​ ​the​ ​following​ ​questions: 1.​ ​Lead​ ​melts​ ​at​ ​620ºF.​ ​Would​ ​a​ ​furnace​ ​that​ ​heats​ ​to​ ​200ºC​ ​melt​ ​the​ ​lead?​ ​Why​ ​or​ ​Why​ ​not?      When​ ​you​ ​convert​ ​200c​ ​to​ ​f​ ​it​ ​is​ ​392c​ ​which​ ​means​ ​the​ ​furnace​ ​would​ ​not​ ​melt​ ​the​ ​lead​ ​at​ ​that​ ​heat​ ​because​ ​it​ ​is​ ​much​ ​to low.. 2​.​ ​Your​ ​instructor​ ​loves​ ​ice​ ​cream!​ ​Would​ ​he​ ​rather​ ​have​ ​1​ ​kg​​ ​of​ ​Rocky​ ​Road​ ​of​ ​10,000​ ​mg​?​ ​Express​ ​both in​ ​grams.      10,000​ ​mg​ ​converted​ ​to​ ​gram​ ​is​ ​10​ ​while,​ ​1​ ​kg​ ​is​ ​1000​ ​grams.​ ​So​ ​my​ ​instructor​ ​would​ ​rather​ ​have​ ​1kg. 3.​ ​ ​How​ ​does​ ​a​ ​hypothesis​ ​differ​ ​from​ ​a​ ​theory?​ ​How​ ​does​ ​a​ ​theory​ ​in​ ​common​ ​culture​ ​differ​ ​from​ ​a​ ​theory in​ ​science? A​ ​hypothesis​ ​is​ ​a​ ​guess​ ​and​ ​a​ ​theory​ ​is​ ​backed​ ​with​ ​evidence.       4.​ ​What​ ​makes​ ​a​ ​good​ ​hypothesis?      When​ ​you're​ ​showing​ ​that​ ​you​ ​have​ ​prior​ ​knowledge​ ​it​ ​makes​ ​for​ ​a​ ​good​ ​hypothesis​ ​while​ ​also​ ​making​ ​sure​ ​to​ ​use​ ​some research​ ​and​ ​guess​ ​an​ ​outcome​ ​that​ ​is​ ​reasonable​ ​and​ ​interesting.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
