Lab 1 Report
Name: Maria Rizzo Naula
The purpose of this lab was to introduce astronomy, show how to measure how far a star in the
sky is when we are standing on top of the earth and knowing the coordinates that are around
us. Also learned to measure central peaks in craters and lunar elevations.
Inclinometers are very helpful on determining the latitude of certain constellations that can be
visible at night. In our case, since we are located on the northern hemisphere, we must find
Polaris first and then site it with the scale which will show your latitude. Inclinometers are
useful because can help determine the angle of elevation of a star. This is used by engineers
when they are installing solar panels on top of a house so they can take the energy from it. This
is not only for stars, but it can also help find satellites and other objects on the sky.
On the second video, to measure the rocket’s highest point, students will be standing on
opposite sides of where the rocket is launched, and they will be using an inclinometer to
measure it. This video shows how to make an altitude tracker at home. Since there are different
locations the students are standing there will be different measurements and an average should
be obtained.
To get the shadow length of each crater I measured with the millimeter ruler from the
terminator to the start of the crater then to find the converted distance I divided the value by
3.54 and finally to get the actual distance multiplied by the vertical diameter which is 17.04. to
find the feature height the formula h= sc/r was used, and this gave the answer if the height of
crater arzachel was higher or lower than the one from mount Everest, which is lower.

I looked up the results, but I could not find any. The height of the Everest is higher than the
crater arzachel. The shadow length of the crater Walter is more than Arzachel because it is more
far away from the terminator line which is the line that divides night and day. In conclusion the
height of the crater walter is higher than arzachel and even almost doubles the height of mount
Everest.
