By the end of today's lesson, I will be able to: (1) explain how solar and lunar eclipse occur (2) define: heliocentric and geocentric solar system, solar and lunar eclipse, umbra, and penumbra
Heliocentric Solar System النظام الشمسي شمسي Helio = sun centric = center Heliocentric This means ‘the Sun at the center’ هذا يعني "الشمس في وسط
Geocentric Solar System Geo = earth centric = center Geocentric This means ‘the Earth at the center’ هذا يعني "الأرض في وسط
Solar eclipse كسوف الشمس A solar eclipse happens when the Moon passes between the Sun and the Earth يحدث كسوف للشمس عندما يمر القمر بين الشمس والأرض
Lunar eclipse خسوف القمر A lunar eclipse happens when the Moon passes into the shadow of the the Earth يحدث خسوف القمر عندما يمر القمر في ظل الأرض
Solar Eclipse كسوف الشمس During a solar eclipse the Moon passes in front of the Sun. The moon casts two types of shadows: خلال الكسوف الشمسي يمر القمر أمام الشمس. القمر يلقي نوعين من الظلال : – Umbra and Penuambra
Lunar Eclipse خسوف القمر During a lunar eclipse the Moon passes into the Earth’s shadow. The Earth casts two types of shadows: أثناء خسوف القمر القمر يمر في ظل الأرض. الأرض يلقي نوعين من الظلال : – Umbra and Penuambra
Understanding The Earth is in orbit around the Sun. The Moon is in orbit around the Earth. Sometimes the Sun, Moon and Earth lie on a straight line. Light travels in straight lines so when the Moon, the Earth, and the Sun line-up, an eclipse happens.
