Time
Solar time: established by the rotation of the earth in regards to the sun.Daylight saving time: Based on the length of daylight hours. During the winter (towards the end), an hour is "lost". This occurs at 2am on the second Sunday in March. During the fall, an hour is "gained". This occurs on the first Sunday in November at 2am.
Standard time: times for different locations on the earth (time zones). Here are the standard times for North America:

Refractor vs. Reflector Telescopes
A refractor telescope uses glass lenses while reflector telescopes uses mirrors to magnify objects at a distance. Telescopes can help students observe and make predictions about celestial objects.
Observing Celestial Objects with the Naked Eye and with a Small Telescope
For a couple nights during the semester, I have watched the stars with my sister using a Star Wheel. Below is document for the Star Wheel used.

A small telescope can also be made at home to view celestial objects if a small telescope is too expensive to buy. The link below is instructions for how to make a small telescope at home.

Planisphere
Planispheres can help identify the relative location of objects in the sky for a certain day and time. A star wheel can be used to help identify the location. Below are the notes (quizzes Planisphere 1 and 2) during my Physics 205 Astronomy class.

An activity was performed with children during a Science Night for elementary students. This activity helped students view constellations in creative ways. Students were able to plot points given to make out a constellation. Students then identified the constellation using a star map (a star wheel can also be used). Students were also able to look through canisters (with constellations) to identify constellations. It was a great experience, students were excited when they found the constellation they plotted or viewed through the canister on the star map. It was a hands-on activity that students could perform by themselves or with help from others. If I were to modify this activity, I would use an more simplified star map and use easier constellations for the canisters. Below are the documents used for the activity. However, the activity was modified. The labels on the plot (titles of the constellations) were whited out so students could identify them on the star map. The canisters were also not labeled so students could use the star map to identify the constellations.
