Throughout the course of the semester, TAs may be assigned various responsibilities regarding A/CL activities in Astro 1. Their primary responsibility will be to assist students in completing various A/CL projects, answering questions as necessary and guiding them in their understanding of the various projects. The TA may or may not be the one assigned to grade the projects (another TA may handle the project grading). The projects which fall under this category are:
One alternative to the night time observing project is the day time solar observing project. If a significant number of students are unable to attend the night time observing, it is possible to assign a TA to assist students with observations of the Sun, with the use of a sunspotter. An example assignment can be found below:
The Changing Night Sky - students study of how the stars appear to move across the sky over the course of
hours as well as months and the reasons why.
The Revolutions of the Moons of Jupiter - students measure the orbits of a number of moons of Jupiter in order to calculate Jupiterís mass as well as gain a better understanding of Keplerís third law.
The Hubble Redshift-Distance Relation - students simulate measuring the redshifts and apparent magnitudes of a number of galaxies in various clusters in order to determine Hubbleís law and use that as an indicator of the age of the Universe.
A number of projects may also be assigned to students which they will be asked to complete on their own, or in pairs or groups. While a TA will not be specifically assigned to assist students with these projects, the class assigned TA associated with each section may devote some office hours to assisting students. A separate TA will be assigned to handle the grading of semester projects for all sections of Astro 1. A list of semester projects is listed below:
