Day and Night
A __________ occurs when the Moon passes between the Sun and the Earth.
solar eclipse
A. It suggests the universe still contains leftover energy from an early hot, dense state.
B. It proves the Sun exploded which created the universe.
C. It shows galaxies do not move.
D. It demonstrates that Earth is the oldest object in space.
A
What is the largest planet in our solar system?
Jupiter
A change in light from distant galaxies that shows they are moving away from us, helping support that the universe is expanding.
Redshift
A space rock that survives passing through Earth’s atmosphere and lands on Earth’s surface.
Meteorite
I am dusty, red, and dry,
Robots roam me, searching why.
Some think humans may visit one day.
What planet am I?
Mars
What do we call spinning of the Earth around the Sun?
Revolution
I explain how the universe began from a hot, dense state long ago.
Galaxies moving apart provide evidence that space is expanding.
Faint microwave radiation left throughout space also supports me.
What theory am I?
Big Bang Theory
What planet is this?
Size: Large
Appearance: Blue/Green, with some white clouds
Axial Tilt: 23.5
Direction of rotation: prograde (same direction as sun)
Earth
Faint energy left over from the early universe
Cosmic Microwave Background Radiation (CMB)
I streak across the sky in a flash of light,
but I am not actually a star.
I burn up as I enter Earth’s atmosphere.
What am I?
Meteor
Name the terrestial planets.
Mercury, Venus, Earth and Mars.
A________________ occurs when Earth passes between the Sun and the Moon, causing Earth’s shadow to fall on the Moon.
lunar eclipse
A. The statement is accurate because the explosion happened at the center of space.
B. The statement is incomplete because the theory describes space itself expanding.
C. The statement is correct because galaxies are stationary.
D. The statement is accurate because Earth existed before the expansion began.
B
What planet is this?
Type: terrestrial
Atmosphere: thick
Appearance: completely covered by clouds
Axil tilt: 2.6
Rotation: retrograde (opposite of sun)
Venus
The force that pulls objects toward each other, keeping planets in orbit around the Sun.
Gravity
I am a rock from space that survives the trip through the atmosphere.
I land on Earth and can be collected by scientists.
What am I?
Meteorite
Example of a Natural Satellite
The Moon
If the last new Moon was on May 8th, which date is the best estimate for when the next new Moon will occur?
A. May 15th
B. May 22nd
C. June 6th
D. June 25th
C
A. It demonstrated that scientific explanations can change with new evidence and technology.
B. It proved all earlier scientific ideas were completely useless.
C. It showed that observations should not influence scientific thinking.
D. It ended the study of astronomy.
A
I am covered in toxic clouds that rain acid.
My atmosphere creates crushing pressure stronger than deep ocean waters on Earth.
What planet am I?
Venus
objects remain at rest or move in a straight line at a constant velocity unless acted upon by an external force.
Inertia
I am a rocky object that orbits the Sun.
Most of my kind live in a belt between Mars and Jupiter.
What am I?
Asteroid
2. Which statements describe a comet? (Select THREE)
A. It is made of ice, dust, and rock
B. It always stays between Mars and Jupiter
C. It can form a glowing tail near the Sun
D. It orbits the Sun in a long, stretched path
E. It is a burning streak of light in Earth’s atmosphere
A, C, D
What causes our planet to have four seasons?
Seasons are the result of the tilt of the Earth's axis.
A. Scientists continued using the geocentric model even after new discoveries.
B. Scientists rejected telescopes because they complicated astronomy.
C. The heliocentric model replaced the geocentric model after observations provided stronger evidence.
D. The Big Bang Theory proved Earth is the center of the universe.
C
Scientists search me for signs of ancient water,
but today I am dry, dusty, and freezing cold.
Humans would need spacesuits and oxygen to survive here.
What planet am I?
Mars
The Sun and all the objects that orbit it, including planets, moons, asteroids, and comets.
Solar System
I am made of ice, dust, and rock.
When I get close to the Sun, I grow a glowing tail.
What am I?
Comet
My rings make me famous,
but I am far too cold for life as we know it.
Like Jupiter, I am mostly gas with no solid ground.
What planet am I?
Saturn
