What is perspective?
How things look depending on where you are and how far away they are.
100
How long does it take Earth to make one complete turn on its axis?
24 hours
100
What causes shadows to form?
blocking of light by an object
100
What is an exoplanet?
a planet that orbits a star outside our solar system.
100
What force pulls objects toward the Earth's center (or"downward")?
Gravity
200
Why does the Sun look bigger than other stars?
Perspective - the sun is much closer to Earth than any other stars
200
What motion of the Earth causes day and night?
Earth's rotation on its axis
200
What happens to shadows throughout the day? (How do they change?)
They change in direction, size and shape.
200
What is a constellation?
A star pattern or group of stars that form an image.
200
Which of these is caused by gravity: a basketball falling through a hoop or a balloon floating up?
A basketball falling through a hoop.
300
What is a celestial body?
any natural object found outside of Earth's atmosphere, including planets, stars, moons, asteroids,, etc.
300
What do we call the path Earth takes around the Sun?
an orbit
300
How would a shadow look at 3 p.m. compared to 9 a.m.?
It would point in a different direction and be shorter than in the morning
300
The Big Dipper is part of which constellation?
Ursa Major
300
What two factors contribute to gravity?
Distance and Mass
400
Give me an example of a luminous object
- The sun.
- Lightning.
- A lightbulb.
- A bonfire.
- A computer screen.
- Fireflies.
- A candle.
- Glowworms.
400
The sun rises in the and sets in the
The sun rises in the East and sets in the West.
400
Why does the length of shadows change throughout the day?
The angle of sunlight changes as Earth rotates
400
Which motion causes different stars to be visible during different seasons?
The Earth revolving around the sun throughout the year.
400
What can you tell me about the gravitational pull of these two planets?
A smaller planet, having less mass, has weaker gravity. Depending on the smaller planets momentum, it may either collide with the larger planet or enter its orbit due to the larger planet's stronger gravitational pull.
500
How is the Sun like other stars? (One reason)
Gives off light and heat, is made of hydrogen and helium
500
What is the terminator line?
The boundary between the light and dark sides of a planet, marking the transition between day and night
500
Left to Right, East to West. Based on this image, what time of day is it? If I wanted to change the time of day to 12:00 pm, what would I have to change in this image?
It is around 3:30/4pm-5pm.
To change to noon, the sun would have to be right on top of the tree and the shadow would be right under the tree - short and stumpy.
500
Do we see the same star patterns all year? Why?
no, we see some only at certain times of the year - due to Earth's rotation of the sun
500
What would be the effects of no gravity on Earth?
Water, plants, people, everything able to be detached from the surface would float away.
