Rotation/Revolution
What causes day and night? (#15)
Rotation of Earth on its axis
What are the 2 most important things that determine the reason for the seasons? (#2 and #7 and #10)
Earth's tilt and its revolution around the Sun.
Why does the Moon shine? (#28)
It reflects light from the Sun to Earth
What makes a good controlled experiment? (#24)
Having only 1 independent variable and keeping everything else constant
Which season has the longest day?
Which season has the shortest day?
(#6)
Summer (June 21)
Winter (December 21)
Explain why cities in the same time zone can different sunrise times. (#1)
Not all portions of the time zone will rotate into the sunlight at the same time; the east portions will receive light first.
Which season is represented by each picture in the diagram? (#2)
**See diagram drawn on the board
A - Summer
B - Fall
C - Winter
D - Spring
What is the difference between waning and waxing? (#18)
Waning is getting smaller and waxing is getting bigger.
What is the ratio of Earth diameter to Moon diameter? (#22)
How big would the Moon be if the model Earth was 400 cm?
1:4 or 1/4
100 cm
What causes (most) craters on the Moon? (#14)
Impact from space objects
How long is a current day/night cycle? (#21)
How would it change if the Earth did not rotate? (#9)
24 hrs
It would become 1 year
What is solar angle? How does it affect light concentration? (#16)
Solar angle is the angle created with the ground and the sunlight.
A higher solar angle creates a higher light concentration and warmer temperatures. The opposite is true for smaller solar angles.
Why don't we have eclipses each month? (#30)
The Moon is not in the exact orbital plane as Earth - it is slightly tilted in respect to the Earth.
What is an independent variable?
What is a dependent variable?
(#19)
IV - What is being tested
DV - The results of an experiment
Give 2 pieces of evidence to support the fact that Earth is round.
(#8)
1. No one has found the edge
2. People have sailed/flown around it
3. We have seen it from space
4. Our horizon
How long does it take for the Earth to complete on revolution? (#20)
How would our revolution change if the Earth did not rotate?
1 year(365 days)
It would not.
Why do temperatures change throughout the year? (#28)
As the Earth revolves around the Sun, our solar angle changes giving us various light concentration. When the solar angle increases so does light concentration which increases our temperatures.
If the Moon is always 50% lit, why do we see different phases? (#11)
Not all of the lit portion of the Moon is in our field of view from Earth.
Give 2 reasons that scientists use models. (#25)
1. Things that are too big
2. Things that are too small
3. Things that are too dangerous
Order the following from smallest to largest. (#23)
Universe, solar system, star, galaxy
Star
Solar system
Galaxy
Universe
Where does the North Pole point during its revolution around the Sun?
How does that change with the seasons?
It doesn't change; it is always pointed in the same direction regardless of season.
Draw a diagram that shows how light hits the Northern Hemisphere during the winter. (#3)
Teacher will draw.
New Moon (Solar Eclipse)
Waxing crescent
1st Quarter
Waxing gibbous
Full Moon (Lunar Eclipse)
Waning gibbous
3rd (Last) quarter
Waning crescent
They demonstrate a more accurate representation
What is the difference between a meteor and a meteorite?
Do either orbit the sun?
(#17)
Meteorites hit the ground
Neither orbit the sun - those are meteoroids.
