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

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
