What happens to the gravitational pull of an object (such as a planet) the further away you get from it?
Gravitational Pull decreases
100
What is the name of the system that contains the Earth, the Sun, and all of the other nearby planets and moons?
The Solar System
100
How does light move?
In straight lines.
100
Why does the sun appear to move across the sky, creating the phenomena of day and night?
The sun isn't moving, the earth is rotating (spinning)
100
How does the sun or any star create energy?
A process called fusion, two atoms are forced into one.
200
How does mass effect gravitational force?
The more mass something has, the more gravitational pull it has.
200
How long does it take for the Earth to complete one revolution in its orbit? How long does it take the moon?
1 year for earth, and 1 month for the moon.
200
What is amplitude refer to?
How big, forceful, or large a wave is.
200
Why does the moon appear to have different phases?
The moon is revolving around the Earth
200
Why do planets and stars have layers?
Planets and stars have layers based upon their density
300
Why does the Earth orbit the sun, and not the other way around?
The sun is significantly more massive than the earth, and has more gravitational pull
300
What color of stars are the coolest in temperature, and which are the hottest?
Red stars are the coolest, and blue-white stars are the hottest
300
What does wavelength refer to?
The distance between any two matching parts of a wave.
300
What causes the seasons on earth?
The axial tilt of Earth
300
Why does Antarctica experience 28 days of darkness starting in June?
The axial tilt of earth points the south pole away from the sun.
400
What is the relationship between gravity and weight?
Weight is caused by gravity
400
What causes the tides?
The gravitational pull of the moon
400
What are the 2 ways in which an object can become visible to us?
1. Gives off light, emits light, or glows.
2. Light reflects off the object
400
Why don't eclipses happen every month?
The moon's orbit around earth is not perfectly aligned with the orbit of the earth around the sun.
400
How can objects made out of steel float in water?
They reduce their density by changing their shape/volume, or by changing their mass.
500
How does gravity influence the creation of astronomical bodies like stars and planets?
Gravity pulls matter together to form stars and planets.

DAILY DOUBLE: Describe at least two things that the sun does to help sustain life on earth.
1. The Sun provides energy for photosynthesis, allowing plants to turn light into food.
2. The sun provides heat to the planet, keeping it warm, and driving its weather
3. The sun guides the earth by keeping it gravitationally bound
4. The sun keeps its area clear, reducing the chance of asteroids or other objects hitting the planet.
500
What type of light has the most energy?
Gamma Rays

DAILY DOUBLE: Alice says that she knows from her people and from science that she is connected to all things - how is Alice correct, scientifically speaking?
1. All matter originated in the Big Bang
2. All matter is connected by gravity
