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

333 Answer the following questions: Describe your procedures for taking the arm length measurement. Is there a standard for measuring arm length?
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
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
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. Fill in the following charts:
