  2. Three Main Subtopics • Objects in the Sky • Changes in the Earth and Sky • The Changes of Earth’s Surface

  3. Table of Content

  4. Phases of the Moon

  5. Phases of the Moon • It takes about 28 days for the Moon to orbit the Earth. This is about one month. • The Moon orbits the Earth about 12 or 12.3 times in one Earth-year. • Though the Moon looks like a lesser light, it does not give off light. The light from the sun always lights one half of the Moon. • There are 8 Phases of the Moon: • *1st Quarter *Waxing Crescent • *New Moon *Waning Crescent • *3rd Quarter * Waning Gibbous • *Full Moon *Waxing Gibbous • Complete the lunar cycle challenge.

  11. Earth on Its axis tilted 23.5 degreesThe tilt of earth on its axis gives our planet the perfect condition for all forms of life to survive.

  12. Our Solar System in Space • The Sun is the nearest star to the Earth • The Sun is 93-Million Miles away • Stars are a great fiery orb of hydrogen and helium gases • Stars come in different colors • The Moon is a satellite of the Earth • The Moon rotates at 10 Miles-per-Hour

  13. Our Solar System and Distance from the Sun

  14. Sunlight is important it heats the earth surface, which warms the air above us. The sun does not heat the earth evenly. The poles are extremely cold, and the tropics around the equator are extremely hot, and because the tropics faces the sun more directly than the N and S poles. In the temperate zones the areas between the tropics and poles, the amount of the heat that’s received from the sun varies during the year because the earth tilts on its axis as it orbits the sun. The variation causes the seasons: summer, fall, winter and spring. The seasons north of the equator are the opposite of the seasons south of the equator. When its summer in the united states, its winter in Brazil. In short if its Summer In North America, its winter in South America.

  15. The Earth's axis is tilted from perpendicular to the plane of the ecliptic by 23.45°. This tilting is what gives us the four seasons of the year: Summer, Spring, Winter and Autumn. Since the axis is tilted, different parts of the globe are oriented towards the Sun at different times of the year. This affects the amount of sunlight each receives. For more information on the seasons, click here. SPEEDAt the equator, the Earth's surface moves 40,000 kilometers in 24 hours. That is a speed of about 1040 miles/hr (1670 km/hr). This is calculated by dividing the circumference of the Earth at the equator (about 24,900 miles or 40,070 km) by the number of hours in a day (24). As you move toward either pole, this speed decreases to almost zero (since the circumference at the extreme latitudes approaches zero). The Earth revolves around the Sun at a speed of about 30 km/sec. This compares with the Earth's rotational speed of approximately 0.5 km/sec (at middle latitudes - near the equator).

  16. You can't measure the speed of an object by itself, it has to be measured relative to something else (this was one of Einstein's realizations). If we ask the question, "How fast the Earth is moving?" we have to specify that we want the speed with respect to another object. Motion cannot be measured without a reference point. We can ask how fast the earth is moving with respect to its own axis, the Sun, the Milky Way Galaxy, or our Local Group of galaxies. The Complex Motion of the EarthHow fast is the Earth spinning? 0.5 km/sec    •How fast is the Earth revolving around the Sun? 30 km/sec    •How fast is the Solar System moving around the Milky Way Galaxy? 250 km/sec    •How fast is our Milky Way Galaxy moving in the Local Group of galaxies? 300 km/sec The Earth spins around its axis as it orbits the Sun. Our entire Solar System slowly orbits around the Milky Way Galaxy. The Milky Way Galaxy belongs to the Local Group of galaxies, where it is also moving. HOW FAST IS THE EARTH SPINNING AROUND ITS AXIS?The Earth is spinning around its axis. At the equator, the Earth's surface moves 40,000 kilometers in 24 hours. That is a speed of about 1040 miles/hr (1670 km/hr or 0.5 km/sec). This is calculated by dividing the circumference of the Earth at the equator (about 24,900 miles or 40,070 km) by the number of hours in a day (24). As you move toward either pole, this speed decreases to almost zero (since the circumference of the spinning circle at the extreme latitudes approaches zero). HOW FAST IS THE EARTH REVOLVING AROUND THE SUN?The Earth orbits, on average, 93 million miles (149,600,000 km) from the Sun (this distance is defined as one Astronomical Unit (AU)), taking one year to complete an orbit. The Earth revolves around the Sun at a speed of about 18.5 miles/sec (30 km/sec). HOW FAST IS OUR SOLAR SYSTEM MOVING WITHIN THE MILKY WAY GALAXY?The sun is about 26,000 light-years from the center of the Milky Way Galaxy, which is about 80,000 to 120,000 light-years across (and less than 7,000 light-years thick). We are located on one of its spiral arms, out towards the edge. It takes the sun (and our solar system) roughly 200-250 million years to orbit once around the Milky Way. In this orbit, we (and the rest of the Solar System) are traveling at a velocity of about 155 miles/sec (250 km/sec). HOW FAST IS THE MILKY WAY GALAXY MOVING WITHIN THE LOCAL GROUP OF GALAXIES?The Milky way Galaxy is just one galaxy in a group of galaxies called the Local Group. Within the Local Group, the Milky Way Galaxy is moving about 185 miles/sec (300 km/sec).

  17. Volcanoes The volcano is known as one of the most destructive forces in human history. Yet we can not reject a vision of how the explosion of the volcano.What is a volcano? The volcano is an opening through which molten rock called magma rises from the earth's land surface. Magma eruption of the volcano lava is known, and is a material that creates a cone around the Vent.The volcano is active, the eruption of lava, creating seismic activity or natural gas release. Sleeping volcano, cut a very long period, but may break out again in the future. If the volcano idling more than 10,000 years, is known to be extinct.Volcanoes may be different in appearance, a perfect cone shape, and other deep pits filled with water. Volcanoes form shows the type and size of the volcano, which is governed by the properties and composition of magma. Size, style and frequency of outbreaks vary widely, but these factors help to create a volcano.How volcanoes formed ?Volcanoes occur where the majority of the two plates together. When two plates move, but is a gap, hot molten rock - called lava - is growing between them. The volcano is the nature of the sea and the most invisible. If the amount is large enough, excess magma of the ocean and the island created.If two plates collide and one plate forced under another plate, which makes its first cuimilte melt and rising magma. But after a few volcanoes in the world who made this, but their outbreaks are the most violent and dangerous. Sometimes it is also a volcano in the middle of the plate, so-called hotspots. These are things involved in a warm blanket.Three main types of volcanoes listed below, which are made in various forms

  19. Why do seasons change Our seasons may change By Mr. Barlow In astronomy, axial tilt is the angle between a planet’s rotational axis and the direction in which it orbits its star. This effect is the main cause of the seasons. Whichever hemisphere is currently tilted toward the Sun experiences more hours of sunlight each day. The Earth spins on an axis that is tilted at about 23.5° from the vertical. But this position is far from constant – the planet’s axis is constantly shifting in response to changes in the distribution of mass around the Earth. The Earth is like a spinning top, and if you put more mass on one side or other, the axis of rotation is going to shift slightly. The influx of fresh water from shrinking ice sheets is causing the planet to pitch over at a rate that may increase significantly in the coming years. What’s more, oceans merely warmed by the rise in greenhouse gases can also cause the Earth to tilt. And all that may very well alter our seasons! Read more here.

  20. Student’s work Students will work in groups of three. As a group they will be able to apply what they learned and write a reflection in their writing journal. • Write a one paragraph reflection of their experience on what they learned and enjoyed while conducting the scavenger hunt. • View the video clips and attach a comment on the video selection • Describe how and what they feel in poem form about the moon, star, or earth • Share out with a partner what they found most interesting about the scavenger hunt. Is it a full moon or is it a new moon? Find out at http://www.enchantedlearning.com/subjects/astronomy/moon/Phases.shtml. Please define and create a drawing to go along with the definition.
