Scale
Scale Description 4
Through independent work beyond what was taught in class, students could (examples include, but are not limited to):
research current and past earth and sun conditions.
investigate causes and possible solutions for global climate change.
compare and contrast the patterns in the organization and distribution of matter in the sun, earth, moon system.
compare and contrast different solar events and their impact on earth. 3
understand how the motions of the sun, stars and planets as observed from Earth relate to the motions of the Earth and other planets in space.
understand how the movement and position of Earth influences life on Earth.
be able to differentiate between astronomy and astrology. 2
determine the meaning of symbols, key terms, and other astronomy specific words and phrases relating to the Earth, Sun and Moon
illustrate the patterns of distribution of matter in the sun, earth, moon system.
list the physical properties of the Earth, Sun and Moon.
describe the key parts of the Earth, Sun and Moon System 1
show the patterns of distribution of matter in the sun, earth, moon system.
select from a list the physical properties of the sun, earth and moon.
list the key parts of the structure of earth, sun and moon.
Open up your laptops, go to MrHyatt.rocks, and do today’s bell work
Afterward, please read the FYI: Seasons article and answer the TWO questions at the end.

2. Due Friday at Midnight

3. To Clarify from Tuesday
Draw this next to your hypothesis number one….
then

4. The Earth isn’t the only thing to rotate and revolve

5. What causes our
seasons?

7. The Sun’s Rays in Summer and Winter.
In summer, the Sun appears high in the sky and its rays hit Earth more directly, spreading out less.
In winter, the Sun is low in the sky and its rays spread out over a much wider area, becoming less effective at heating the ground.

5. The seasons (have NOTHING to do with the location or distance of earth relative to the sun) are caused by the tilt of earth’s axis which causes light to hit the earth at an indirect or direct angle.
Earth is, on average 93,000,000 miles (150 million km) away from the sun, and its distance from the sun varies by about 3%
Perihelion (closest to sun)
– 147 million km - January 3
Aphelion (farthest from sun)
– 152 million km – July 4

9. The Sun’s Rays in Summer and Winter.
In summer, the Sun appears high in the sky and its rays hit Earth more directly, spreading out less.
In winter, the Sun is low in the sky and its rays spread out over a much wider area, becoming less effective at heating the ground.

4. The sun can only ever be directly overhead if you are within the tropic (tropic of Cancer and tropic of Capricorn) lines.
tropic of Cancer - north, Capricorn - south

12. Earth on June 21. This is the date of the summer solstice in the Northern Hemisphere. Note that as Earth turns on its axis (the line connecting the North and South Poles), the North Pole is in constant sunlight while the South Pole is veiled in 24 hours of darkness. The Sun is at the zenith for observers on the Tropic of Cancer.

13. Earth on December 21. This is the date of the winter solstice in the Northern Hemisphere. Now the North Pole is in darkness for 24 hours and the South Pole is illuminated. The Sun is at the zenith for observers on the Tropic of Capricorn and thus is low in the sky for the residents of the Northern Hemisphere.

14. Top 5 things to know about the motion of Earth…
3. Because of earth’s axial tilt, there are some areas of earth (above about 66∘ N and S) that receive constant daylight and constant darkness during their summer and winter.

What do you think those latitude lines are called?
Arctic Circle and Antarctic Circle

2. Seasons are reversed in the southern hemisphere.
Northern hemisphere summer: July
Southern hemisphere summer: December
Northern hemisphere winter: December
Southern hemisphere winter: July

20. Seasons. We see Earth at different seasons as it circles the Sun
Seasons. We see Earth at different seasons as it circles the Sun. In June, the Northern Hemisphere “leans into” the Sun, and those in the North experience summer and have longer days. In December, during winter in the Northern Hemisphere, the Southern Hemisphere “leans into” the Sun and is illuminated more directly. In spring and autumn, the two hemispheres receive more equal shares of sunlight.

21. Top 5 things to know about the motion of Earth…
1. earth’s rotation causes the sun (and stars) to appear to move across the sky. The sun rises in the east and sets in the west because we spin counterclockwise.

23. You have the rest of today to finish this – Due at Midnight
