Lap - Lab Report ExampleExplanation of Procedure A meter stick was mounted at slightly greater than eye level, level to the ground. A plumb bob bob, actually a string with a nut tied to the end, hung at head level on the dot 0.5 meters from the meter stick. This served as an observation post with easily converted and consistent measures. As the moon full rose past the horizon, two index cards were butted to either edge of the moon and the indicated length was recorded. This affair was repeated later. Data and Calculations The chart results time d (cm) D (cm) conversion ? 710 50 0.5 205265 2053 1010 50 0.5 205265 2053 Where d=50 cm as set by the experiment. D= the measure between the cards ?=the angle size of it of the moon in arc seconds calculated as =(D/d) x 205265 The diameter of the moon is calculated as D= (205265 x 2053)/ 380000km d=3800 km The angular size of the moon by calculation is 2053 arc seconds The estimated diameter of the moon is 3800 km The angular size of the moon is consistent throughout a one night period however, the distance to the moon varies everywhere time, so over years, the angular size changes Conclusions and Analysis The method used produces a good resemblance of the diameter of the moon.
