Slide 3
Steps : 1 : We found Katys and Simones height 2: Next we found
Katys and Simones height of their shadow 3: Then we used Katys
height and put in the proportional equation with the height of the
monuments shadow and got the height of the monument itself 4: Last
we converted the centimeters into feet Fact : For this procedure
you needed the sun for its shadow.
Slide 4
1 : Katys Height - 165 cm Key to Conversions : Converted into
feet 5.4 ft. Cm - > ft. : divide by 30.48 2 : Simones Height 164
cm Converted into feet 5.3 ft. 3 : Katys Shadow Height 261 cm
Converted into feet 8.5 ft. 4 : Simones Shadow Height 276 cm
Converted into feet 9 ft.
Slide 5
Proportions set up : Monuments height : (x) Shadow 1 :
Monuments shadow height Students height (Simones/Katys): 5.3 ft. /
5.4 ft. Shadow 2 : Students shadow height(Simones/Katys):9 ft./8.5
ft. Simoness/Katys distance between steps : 64 cm/ 90cm Steps Taken
Simoness/Katys : 365 /351 Katys Trail : X / 5.4 ft.. = 1036 ft. /
8.5 ft. 8.5 ft. (X) = 5594 ft. 5594 ft. / 8.5 ft. = x X = 658 ft.
Simones Trail : X/5.3 ft.= 757 ft./ 9 ft. 9 ft. (x) = 4012 ft.
4012ft./9ft = x X= 446 ft Averaged : 658 ft. + 446 ft. =1104 1104/2
= 552 ft.
Slide 6
Steps : 1 : We had Simone get lined up with the monument ( Her
head to the top of the monument) 2 : We used a camera to see if her
head was lined up with the tip of the monument 3 : We found the
distance from Simones position to the monument and from Simone to
the camera 4 : Next we added the distances of Simone from the
camera and Simone to the monument and found the total 5 : And then
we took Simones height in the equation 6 : Lastly we did the
calculations and found the height of the monument
Slide 7
Cameras height : 79 cm - > 3 ft. 1 : Katys height : 165 cm -
> 5.4 ft. 2 : Distance to Katy : 250 cm - > 8 ft. 3 :
Distance to Monument : 165 ft. 1 : Simones height : 164 cm - >
5.3 ft. 2 : Distance to Simone : 250 cm - > 8ft. 3 : Distance to
Monument : 221 ft.
Slide 8
Total Distance : 150 x 78 = 1170 cm -> 380 ft. Simones
height : 164 cm - > 5.3 ft. Cameras height : 79 cm - > 3 ft.
X-3 ft. / 5.3ft. = 388 ft. / 8 X-3 / 2.3 = 388/8 8(x-3)=892
8x-24=892 +24 +24 ___________ 8x=916 ft. 916/8= 114.5 -> 115 ft.
X= 115 ft.
Slide 9
Difference : The difference between procedure A and B is that A
was based on the shadow and for procedure B it was based on the
camera. Similarity : The similarity was that both were ways to find
the height of something using different types of strategies. In my
opinion I think procedure A was a better strategy to use because it
was based on a shadow and since the sun was out it was easy to
measure it, also because it had less steps. Procedure B was
challenging because it depended on how you held the camera, if it
was on the ground or if you kneeled down and it had a height.
