OBJECTS IN THE SKY Amy Howland EDUC 470 March 2016 THIRD GRADE SCIENCE CONTENT STANDARDS: EARTH SCIENCE 4. Objects in the sky move in regular and predictable patterns. As a basis for understanding this concept: B. Students know the way in which the Moon’s appearance changes during the four-week lunar cycle. D. Students know that Earth is one of several planets that orbit the Sun and that the Moon orbits Earth. E. Students know the position of the Sun in the sky changes during the course of the day and from season to season THE LUNAR CYCLE • The moon continually orbits around the earth. This orbit takes 4 weeks to complete. • Orbit means the curved path of a celestial object or spacecraft around a star, planet, or moon, especially a periodic elliptical revolution • During the 4 weeks, the moon goes through phases- the sunlight portion that is visible from earth. THE LUNAR CYCLE Phase 1- New Moon – Moon is not visible in the night sky THE LUNAR CYCLE Phase 2- Waxing Crescent – A small part of the moon is beginning to show. A little bit more of the moon shows for longer each night THE LUNAR CYCLE Phase 3- First Quarter – Half the moon is visible for the first half of the night. THE LUNAR CYCLE Phase 4- Waxing Gibbous – The moon is almost fully visible and stays in the sky for most of the night THE LUNAR CYCLE Phase 5- Full Moon – We can see the entire surface of the moon during this phase. The moon stays in the sky all night. THE LUNAR CYCLE Phase 6- Waning Gibbous – The entire moon is almost all visible. Each day that passes, we see a little LESS of the moon THE LUNAR CYCLE Phase 7- Last (or 3rd) Quarter – We can see ½ of the moons surface THE LUNAR CYCLE Phase 8- Waning Crescent – We can see only a sliver of the moon THE LUNAR CYCLE After phase 8, the cycle begins again with a new moon PLANETS THAT ORBIT THE SUN • There are 9 planets that orbit around the sun PLANETS THAT ORBIT THE SUN • Mercury – closest to the sun – Mercury goes around the sun once every 88 earth days PLANETS THAT ORBIT THE SUN • Venus – 2nd from the sun – It takes 224.7 Earth days for Venus to orbit the sun. It has the longest rotation period of any planet in the Solar System. It unusually rotates in the opposite direction to most other PLANETS THAT ORBIT THE SUN • Earth – 3rd from the sun – It takes earth 365 days(1 year) to orbit around the sun. – This is the only known planet to have life on it. PLANETS THAT ORBIT THE SUN • Earth has one moon that orbits around it. • Earth’s moon is one of the largest satellites in the solar system PLANETS THAT ORBIT THE SUN • Mars – 4th from the sun – Mars orbits the sun every 1.88 earth years (or 686.93 earth days). PLANETS THAT ORBIT THE SUN • Jupiter – 5th from the sun – Jupiter orbits around the Sun once every 11.86 Earth years, or once every 4,330.6 Earth days. – Largest planet in the Solar System PLANETS THAT ORBIT THE SUN • Saturn – 6th from the sun – Saturn revolves around the Sun once every 29.4 Earth years, or once every 10,755.7 Earth days – Second largest planet PLANETS THAT ORBIT THE SUN • Uranus – 7th from the sun – Uranus orbits around the Sun once every 84 Earth years, or once every 30,687 Earth days – Uranus has 27 moons PLANETS THAT ORBIT THE SUN • Neptune – 8th from the sun – Neptune takes 164.79 earth years to orbit around the Sun PLANETS THAT ORBIT THE SUN • Pluto (dwarf planet) – 8th farthest from the sun – Pluto takes 248 years to orbit the Sun THE SUN IN THE SKY • The sun always rises in the East and sets in the West THE SUN IN THE SKY • The sunrise occurs in the East and as the day progresses, the sun moves across the sky. By the middle-part of the day, the sun will reach the highest point in the sky. After the middle of the day, the sun will begin making its descent in the West. THE SUN IN THE SKY • During the different seasons (winter, spring, summer, and fall) the sun is in a different position in the sky THE SUN IN THE SKY • In the summer, the sun is higher in the sky • In the winter, the sun is lower in the sky
