Sit in assigned seats Not wondering around the roomSharpened pencil out, ready to begin
Warm up….Last Friday we reviewed the rock cycle and how soil is formed.
As you know, soil is a mixture of different materials
List at least 4 materials that make up soil
Warm up….here are 6 ingredients
Sediment (weathered rock particles) largest amount
Humus (decomposed organic matter from plants and animals)
Minerals (building blocks of rocks) Bacteria and fungi (decomposers) Water Air
Remember…The process of soil formation takes hundreds of thousands of years
Remember….Soil forms from broken down
weathered rock; it mixes with surface materials
1st EOG test this Friday, May 23rd Language Arts
You will take all EOG and MSL tests with your 1st block teacher
PLEASE LEAVE YOUR PHONES AT HOME BRING A NOVEL TO READ WHEN YOU ARE
DONE
Announcements….
Is to review….. Rotation and revolution, how day and night happens, why we have seasons, what lunar and solar eclipses are, and why oceans have high tides and low tides.
Our mission today…
Orbit: path the Earth follows as it moves around the sun . The Earth’s orbit never changes!
GUIDED NOTES….
Axis = an imaginary line that goes from the North pole to the South pole that the Earth rotates (spins) around.
FAKE LINE
GUIDED NOTES….
The Earth is tilted on this imaginary axis at 23.5 °
GUIDED NOTES….
‘Earth’s Rotation on its axis
Causes day and night to happen
GUIDED NOTES….
1 complete rotation = 24 hours = 1 day on Earth
Sunrise to sunrise, Sunset to sunset Midnight to midnight, Noon to noon
GUIDED NOTES….
GUIDED NOTES….DRAW
‘Revolution’ isThe movement of an object around another object
The EARTH revolves around the SUN
The moon revolves around the Earth
GUIDED NOTES….
The Earth completes 1 revolution around the sun in 1 year (365 and ¼ days).
GUIDED NOTES….
The Earth’s moon completes 1 revolution around the Earth in ~29 days (8 different phases of the moon)
GUIDED NOTES….
What causes the seasons to change?
Explain why it is spring in North Carolina and Canada but fall in South America and Australia?
Let’s think about this…

Video “Reason for the Seasons”
The tilt of the Earth’s axis as it revolves around the Earth causes the seasons
GUIDED NOTES…..
GUIDED NOTES….DRAW AND LABEL the 4 SEASONS (N. Hemisphere)
summerfall
spring
winter
Seasons are opposite in the 2 hemispheres
Summer in the Northern Hemisphere = Winter in the Southern Hemisphere
Remember the intensity of the sun’s radiation!
Did you remember….

Video on Seasons
Throughout the day, the sun is in different locations in the sky. Which is moving, the sun or the Earth? (circle the right answer)
GUIDED NOTES….
Equator : an imaginary line divides the Earth into Northern and Southern hemispheres
0°latitude
GUIDED NOTES….
Tropics receive greatest amount of solar radiation Sun’s rays are direct and most intense here
Temperatures are always hot
GUIDED NOTES….
Polar Regions receive least amount of solar radiation Sun’s rays hit at an angle Temperatures are usually cold
GUIDED NOTES….
WINTER SOLSTICE – 1ST DAY OF WINTER
SUMMER SOLSTICE- 1ST DAY OF SUMMER
SPRING EQUINOX – 1ST DAY OF SPRING
AUTUMNAL (FALL) EQUINOX – 1ST DAY OF FALL
GUIDED NOTES….
WINTER SOLSTICE – 1ST DAY OF WINTER
N. Hemisphere = shortest amount of daylight
SUMMER SOLSTICE- 1ST DAY OF SUMMER
N. Hemisphere = longest amount of daylight
GUIDED NOTES….
SPRING EQUINOX – 1ST DAY OF SPRING
AUTUMNAL (FALL) EQUINOX – 1ST DAY OF FALL
Equinox = equal amounts of daylight and darkness
GUIDED NOTES….

BrainPOP! Tides
TIDES: The movement of oceans and seas due to the gravitational pull of the moon and sun Tides are due to gravity!This ocean water movement causes high tides (rise of water) and low tides (fall of water)
GUIDED NOTES….

Bay of Fundy Time Lapse Video
Coastlines = 2 high tides and 2 low tides each day (24 hours)
Tides are predictable (we know when they will happen)
Tide Tables = list 2 high tides and 2 low tides for coastal regions each day
GUIDED NOTES….
Spring Tides = extra high and very low tides
formed when the earth, sun and moon line up in a straight line
Straight line, think S = SPRING TIDES
happens every two weeks during a new moon or full moon.
GUIDED NOTES…
Draw this picture….
Neap Tides= high and low tides with very little change
formed when the earth, sun and moon form a right
angle (like a L shape) Think “L” - ”M” - ”N” in the alphabet L (Lowest) M (means) N (neap tides) Neap tides happen during a quarter or three-
quarter moon
GUIDED NOTES….
Draw this picture….

BrainPOP! Eclipses
An eclipse occurs when one object gets in between you and another object and blocks your view.
From Earth, we experience two kinds of eclipses: an eclipse of the Moon and an eclipse of the Sun.
GUIDED NOTES….
Lunar EclipseWhen the Earth blocks sunlight from reaching the moon
Earth's shadow falls on the Moon
GUIDED NOTES…..
DRAW A LUNAR ECLIPSE
Solar Eclipse When the moon passes between the sun and the Earth
The moon blocks the sun’s light from reaching Earth
GUIDED NOTES….
DRAW A SOLAR ECLIPSE
