Context In this lesson, students learn more about the patterns of stars in the night sky by engaging in an interactive activity called Star Search as well as a hands-on activity where they explore the night sky. These activities help emphasize that stars appear to move during the night, but really the earth is rotating and we are moving. As the earth makes its annual journey around the sun, different star patterns are seen in the night sky. The Motivation uses a tool that shows what the night sky looks like on any given date and is used to show that, from month to month, the constellations have a different location in the sky. Then, in the Development, students should do the Star Search activity, which delves a bit deeper into specific constellations and the stories behind them. It introduces constellations in the night sky and the concept that the locations of these constellations are different depending on the season. Finally, students make a sky map which will guide and inspire them to do their own star gazing. The hands-on activities are an introduction to star gazing.

The Mythology of the Constellations Most ancient cultures saw pictures in the stars of the night sky. The earliest known efforts to catalogue the stars date to cuneiform texts and artifacts dating back roughly years. These remnants, found in the valley of the Euphrates River, suggest that the ancients observing the heavens saw the lion, the bull, and the scorpion in the stars. The constellations as we know them today are undoubtedly very different from those first few–our night sky is a compendium of images from a number of different societies, both ancient and modern.
By far, though, we owe the greatest debt to the mythology of the ancient Greeks and Romans. The earliest references to the mythological significance of the Greek constellations may be found in the works of Homer, which probably date to the 7th century B. In the Iliad, for instance, Homer describes the creation of Achilleus’s shield by the craftsman god Hephaistos: On it he made the earth, and sky, and sea, the weariless sun and the moon waxing full, and all the constellations that crown the heavens, Pleiades and Hyades, the mighty Orion and the Bear, which men also call by the name of Wain:
Welcome to Your Sky , the interactive planetarium of the Web. You can produce maps in the forms described below for any time and date, viewpoint, and observing location. If you enter the orbital elements of an asteroid or comet, Your Sky will compute its current position and plot it on the map. Each map is accompanied by an ephemeris for the Sun, Moon, planets, and any tracked asteroid or comet.
A control panel permits customisation of which objects are plotted, limiting magnitudes, colour scheme, image size, and other parameters; each control is linked to its description in the help file.

Yet, one thing stands out, so central to our understanding of space. What are Stars Made of? The thing that makes up stars is truly out of this world. Plasma is a clump of atoms whose electrons have been taken from them. This makes it kind of like a gas. What else is made of plasma, for reference? On Earth, we find it naturally in lightning. The simplest are neon signs. These signs energize electrons on neon atoms, pulling them away to form plasma!
Why is plasma so rare? Plasma is the most common state of matter in the universe. But, it only exists in extreme heat. How do Stars Form? Our discussion of plasma raises another question.
It was named after Hercules, the Roman version of the Greek hero Heracles. Heracles, in turn, was often associated with the Sumerian hero Gilgamesh, and the constellation itself has a long history, dating back to Sumerian times. Hercules is the fifth largest constellation in the sky, but has no first magnitude stars. In mythology, the constellation Hercules is usually associated with the penultimate labour of Heracles, which involved killing the dragon Ladon, who guarded the garden of the Hesperides.
The dragon is represented by the constellation Draco.
Sumerian Gudea Cylinder A ( BC) has clear mention of many star groups or signs. Mesopotamian tablets dating about B.C. record both star names and the observations of planetary movements.
So, are we doing astrology here? A reasonable question with a short answer. Astrology holds that stars exert forces on men. Astrology is a… form of divination based on the theory that the movement of the celestial bodies—the stars, the planets, the sun and the moon—influence human affairs and determine the course of events. But it prohibits worship of what we see above or even holding such things in too high regard. For example, we read in the Book of Job, Chapter Still, the Bible does make a surprising number of references to signs in the heavens.
Both Old and New Testaments assume that what happens up there matters. If we are interested in following the counsel of the Bible, we must hold a distinction in mind. Astrology assumes that stars are causes of earthly events. The Bible assumes that they can be messages about earthly events. It may be useful to think of this as a thermometer distinction.
