Comets

(View Complete Item Description)

Comets played an important role in the revolution of astronomy and cosmology that occurred between 1500 and 1700. In the earlier Aristotelian geocentric cosmological scheme, the universe was divided into two regions with very different characteristics. The heavens, which reached from the sphere of the Moon to that of the fixed stars, were perfect and unchanging; motion there was exclusively circular. Below the Moon was the world of corruption and change. The Earth was the center of the universe, the natural place of all heavy bodies (bodies in which the element earth predominated). Around it were arranged in successive spherical shells the elements of water, air, and fire. The sphere of fire reached up to the sphere of the Moon, the first heavenly sphere. Although there are references in Aristotle that some of the imperfection of the sublunary region may have rubbed off on the Moon, basically the divide between the heavenly and sublunary regions was absolute.

Gravity and Orbits

(View Complete Item Description)

Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it!

Astronomy Star Project

(View Complete Item Description)

This is a project I assign my students in an introductory, non-science major astronomy class. Each student is assigned one of the 25 brightest stars in the sky and they are asked to research and apply concepts they have been learning in the class to their particular star. I leave it up to them to decide the format of their final project - most do PowerPoint but some have done videos or podcasts. One student actually landed a part time job at a radio station after they heard her recording her star project! Many students tell me this is a highlight of the course!

Using PhotoVoice in the Classroom

(View Complete Item Description)

This PhotoVoice assignment is what I use in my astronomy class to get students to prepare for the final exam. They need to find a photograph illustrating a concept covered in the course and then explain it in a paragraph. They post these on the discussion board so others in the class can read and comment as desired.

Lunar Observation Project

(View Complete Item Description)

The month-long lunar observation project I have all students in my AST 1002 Descriptive Astronomy class complete. I helps them understand the phases of the Moon, the relationship between lunar phases and tides, and just gets them outside looking up! Many students say this is the best part of the course.
