STANDARDS Grade 5 TOPIC BACKGROUND Earth Sciences 5. (b,c) The solar system A solar eclipse occurs when the Moon passes between Earth and the Sun in such a way includes the planet Earth, that the Sun is either partially or totally hidden from view. This type of phenomenon can the Moon, the Sun, eight only happen during the new Moon phase of the Moon cycle, when the Sun and Moon are other planets and their satellites, and smaller in conjunction when seen from Earth. objects such as asteroids and comets; the path of a Our Moon’s shadow has two distinct parts: the penumbra and the umbra. The penumbra planet around the Sun is is the faint outer shadow, where a portion of reflected light from the Sun is still visible. due to the gravitational When the Moon’s not-so-dark penumbral shadow hits a region of Earth, a partial solar attraction between the Sun eclipse occurs because the Sun’s light is still partially visible. The darkest part of the and the planet. Moon’s shadow is called the umbra. This is the innermost part of the shadow, the place where sunlight is completely concealed. When the umbral shadow strikes our planet, a Grade 6 total eclipse occurs because the light of the Sun is completely blocked from view. Energy in the Earth System Between two and five solar eclipses occur each year, but not all of them are total 4. (a) The Sun is the major eclipses. In fact, a total eclipse typically occurs only once every one or two years. Other source of energy for types of solar eclipses are partial, annular and hybrid. Annular eclipses are partial phenomena on Earth’s surface. eclipses that occur when the Moon is in a specific orbital phase. An annular eclipse looks almost like a total eclipse, except that there’s a visible ring of fiery sunlight surrounding Grade 8 the dark Moon. If an eclipse occurs while the Moon is in orbit near Earth, it appears as a Earth in the Solar System total eclipse because the Moon looks larger than the Sun from Earth. But if an eclipse (Earth Sciences) occurs when the Moon is in the far side of its orbit, the Moon looks smaller than the Sun 4. (d) Stars are the source and its umbral shadow won’t be long enough to completely block the Sun from view, thus of light for all bright objects creating an annular eclipse. in outer space. Hybrid eclipses are rare treats for eclipse enthusiasts. They’re a blend of both annular Grades 9-12 and total eclipses. Depending on where you are in the world when you watch a hybrid Earth’s Place in the eclipse, you’ll see either a total or annular eclipse, since hybrids flip-flop between the two Universe in following their orbital path.

    THE MOON CYCLE 101:​ ​WHAT DOES THE MOON MEAN FOR US? In astrology, the moon represents our ​inner world (feelings + desires)​, whereas the sun represents our ​outer world (how we ‘show up’ in the world)​. The moon phases mirror our emotional / energetic phases -​ our energy begins to build at the start of a cycle, then reaches a peak at the full moon. After that, it wanes again like diminishing moon, until the cycle ends. We can align our actions with the moon cycle to make our manifesting easier. One full lunar cycle around the earth is 29.5 days.

  • Hawaiian Moon Phases
    Hawaiian Moon Phases Do you know the Hawaiian Moon Phase Song? In Hawaiʻi, we have names for each of the moon’s phases. And here is a song you can sing to learn the 30 Moon phase names in a Hawaiian. Use your Moon Phase Dial to stay on point! Mele: Nā Pō Mahina Song: Hawaiian Moon Phases Kamaliʻi ‘ike ‘ole i ka helu pō “Children who do not know how to count the nights” Muku nei, Muku ka malama “Muku is here, Muku the dark moon” Hilo nei, kau ka Hoaka “Hilo, followed by Hoaka” ‘Ehā kū, ‘Ehā ‘ole “Four kū, four ‘ole” Huna, Mohalu, Hua, Akua “Huna, Mohalu, Hua, Akua” Hoku, Mahealani “Hoku, Mahealani” Kulu! “Kulu!” ʻEkolu lāʻau, ʻekolu ‘ole, ʻekolu kāloa “Three Lāʻau, three ‘ole, three kāloa” Kāne, Lono, Mauli, pau! “Kane, Lono, Mauli, finished!” What is a moon phase? And why is the Moon going through different phases? Well, the moon does NOT give off any light. We see the moon because the Sun’s light is reflecting off of the Moon. The “phase” of the Moon is how much of the Moon appears to us. Take a look at this gif that shows each of the phases of the Moon in a month. GIF of Moon going through itʻs Moon Phases https://www.ilibrarian.net/moon_phase_movie.gif Why do we see the phases of the moon? Well, the moon isnʻt changing shape, it is how we see the moon while it is orbiting the Earth. Around once a month, the phases of the Moon make one complete cycle.

  • Moon Magick ©
    Moon magick © This report looks at some magickal activities that can be done with the moon, apposite really (at the time of writing) in view of the full super blood moon and forthcoming lunar eclipse. It is likely that one could write a book on this topic, but here I’ve looked at the different moon phases and some practical magick during those times. Naming the moon First things first though – let’s start by considering the different adjectives applied to the lunar months during the year – well, not all of them, but some of the more common ones given to the full moon in each month. In the end, I decided on a table, but the sources range from First Nation tribes to Gardnerian Wicca and from Celtic to agricultural. Month Moon names January Hunger, wolf, cold February Snow, quickening March Worm, sap, storm, chaste April Pink, rain, wind, egg, seed, crow May Flower, milk, hare June Rose, strawberry, sun, honey, lover’s July Deer, blessing, hay, thunder, mead August Sturgeon, fish, corn, grain, wort, barley September Corn, fruit, harvest October Hunter’s, harvest, blood, falling leaf November Beaver, mourning, frost December Cold, oak, long night Moon timings are important too. That’s why this report is split into the four main moon phases or quarters and your spells need to be aligned with the appropriate moon phase. Each complete cycle of the moon lasts 28 days and there are four phases of roughly 7-8 days apiece. Within the 28-day period, there are several distinct stages, ie: ➢ New moon.

  • How the Moon's Phases Occur
    This shows how the Sun’s rays reflect a different portion of the Moon back to a viewer on Earth. When the Moon is between the Earth and the Sun, it is a new Moon. About 7 days later, or about ¼ the way through its full period, only half the Moon appears lighted (this is sometimes called a first quarter Moon…NOT because of how much appears lighted but because of what fraction of its cycle has passed since the new Moon. Half way through the Lunar (about 14 days after new) cycle, the Moon is full (also called a second quarter Moon…NOT because you see any “quarters of the Moon but because the Moon is through 2 quarters of its cycle). The Lunar cycle, or time it takes for the Moon to return to the phase in which it began (new Moon to new Moon or full to full) is 29.5 days. Since the number of days in a month does not match this 29.5 day cycle, the day a full Moon falls on is constantly shifting. Some students might find a shortcoming of this illustration. It is the position of the Sun. This illustration works for the first 2 quarters of the cycle…~14.75 days, but if one looks at the illustration, how can the Sun light up the waning gibbous Moon if it is shining from the right and the left side of the Moon appears lighted? This is because the Sun is shifting in its position in relation to the Moon and the illustration fails.

  • Is the Rabbinical Molad/Lunar Conjunction New Moon?
    Is the Rabbinical Molad/Lunar Conjunction New Moon? Shalom. It is the duty of Man to serve the Alohym of Ysrayl by keeping his commandments (Ecclesiastes 12:13). In (gen 1:14) we learn that Both the Sun & moon were given the authority to be for Signs and govern Days, Years & Moedim. Thus ALL of Alohym’s holy Moedim is to be governed by the observation of Sun & Moon. In this topic we will cover New Moon and in retrospect its reckoning of Conjunction (Molad). We will use several witnesses to confirm the legitimacy of this reckoning type and also show its history which will in turn prove its legitimacy. Modern Reckoning of New Moon The modern understanding of New Moon is astronomically calculated and defined as ‘Lunar Conjunction’, which is when the moon is in its dark phase and is blocked from the suns light by the earth; however this was not always how New Moon was reckoned. The ancient Israelites regarded New Moon by its first appearance or sliver of light. Wikipedia Quotes: “In astronomy, new moon is the first phase of the Moon, when it lies closest to the Sun in the sky as seen from the Earth. More precisely, it is the instant when the Moon and the Sun have the same elliptical longitude. The Moon is not normally visible at this time except when it is seen in silhouette during a solar eclipse. See the article on phases of the Moon for further details. The original meaning of the phrase new moon was the first visible crescent of the Moon, after conjunction with the Sun.

    Astronomy and time Astronomical observations led to the development of the modern calendar The day is based on the Earth's rotation The year is based on the Earth's orbit The month is based on the Moon©s orbit Note ©based on©, not ©equal to©! None of these quantities are exactly constant, so astronomers use the average or mean day and leap years to keep the calendar and time consistent Leap Years The Earth orbits the Sun in 365.2425 days. Therefore, the calendar year of 365 days drifts by 0.2425 days each year. With an extra day every four years, the drift is reduced to -0.0075 days per year, or -0.75 days per century. Century years are not leap years, unless they are also divisible by 400 (so 2000 was a leap year). By missing three leap days every four centuries, the 0.75 days per century drift is corrected. The tiny remaining drift will not need correcting for millennia yet. Leap Years ± a historical digression The current leap year rules form the basis of the Gregorian Calendar. This replaced the earlier Julian Calendar, in which every fourth year was a leap year. The Julian calendar slowly drifted relative to the seasons. On the adoption of the Gregorian Calender in Britain in 1752, the large drift accumulated over 1500 years was corrected by skipping straight from Wednesday 2 September to Thursday 14 September.

  • Athena's Birth on the Night of the Dark Moon
    Journal of Hellenic Studies 137 (2017) 175–183 doi:10.1017/S0075426917000131 © The Society for the Promotion of Hellenic Studies 2017 ATHENA’S BIRTH ON THE NIGHT OF THE DARK MOON CATALIN ANGHELINA The Ohio State University/University of Bucharest* Abstract: The exact days on which the Panathenaia was celebrated are not altogether clear, with the exception of Hekatombaion 28 (I 28), the day of the great πομπή honouring Athena. In two ancient scholia it is said that Athena’s birthday was celebrated on this main day of the festival. This information has often been deemed false, owing to the existence of other, conflicting testimony according to which Athena’s birthday was celebrated on the third of each month, a fact seemingly in accord with her epithet of Tritogeneia. The association between I 28 and Athena’s birthday has been seen as the result of the confusion generated by I 28 being the third day from the end of the month (τρίτη ἀπιόντος). I argue that the information contained in the scholia is not the result of confusion. Athena’s birthday was indeed celebrated on the main day of the Panathenaia. This date was set in stone by Pheidias on the Parthenon’s east pediment. Keywords: Athena’s birthday, dark moon, Parthenon sculptures, Parthenon east pediment, Selene The festival of the Panathenaia was the most important religious celebration in ancient Athens.As is well known, it occurred in two forms: a regular annual festival, the Lesser Panathenaia, and, every four years, a more grand and spectacular celebration, the Great Panathenaia.1 It is not alto- gether clear which were the exact days of the festival.
