100
The distance the marble traveled when it was rolled slowly down the ruler
What is a short distance.
100
The marble in this model represents this.
What is a planet or moon
100
The marble in this model represents this
What is planet or moon
100
Define orbital period.
The time it takes a moon or planet to orbit or revolve around (a more massive object) once.
100
This motion results in the length of a day
What is the Earth's rotation.
200
The distance the marble traveled when it was rolled quickly down the ruler.
What is the longer (or longest, furtherest) distance.
200
The marble and jar lid (ring) station modeled this.
What is the orbital path a planet or moon takes due to inertia and gravity.
200
The balloon in this model represents this
What is the sun (or a planet).
200
State how the mass of the cylinder affects the speed of the sphere's orbital period.
What is the more mass the cylinder has the faster the orbital period. (And/Or The less mass the cylinder has the slower the orbital period.)
200
This motion results in the length of a year.
What is the Earth revolving around the sun.
300
The two forces acting on the marble when held in your hand.
What is gravity and normal force. (alternate acceptable: force of your hand pushing up)
300
This happened to the marble when you lifted the ring.
What is flew off in a straight line (or similar response).
300
Draw what happened when you rolled the marble onto the spandex sheet.
What is circled the more massive object until it fell into it. (drawn).
300
How do you think scientists determine the mass of the planets?
What is planets with moons that have a short orbital period are more massive than planets with moons that have a long orbital period
300
Draw the position of the Sun, Earth, and Moon to cause a Lunar Eclipse. Label the umbra and penumbra.
What is Sun, Earth, moon, in a line. (Drawn)
400
This factor affected the distance the marble traveled once it left the ruler.
What is speed.
400
This is what would happen to a planet if the unbalanced force of the sun was removed.
What is the planet would fly off in a straight (tanget) line to the orbital path.
400
This describes how the motion of the marble changes as it nears the balloon
What is its orbital path (circular path) became smaller and smaller.
400
State the relationship between orbital speed and orbital period.
What is ...the faster the orbital speed the shorter the orbital period (or vice versa).
400
Draw and label a solar eclipse.
What is Sun, moon, Earth lined up.
500
This is the pulling force that acts on the marble at all times
What is gravity.
500
The two forces responsible for the orbital path of a planet or moon around a more massive object
What are inertia and gravity
500
This planet would have the fastest orbital speed.
What is Jupiter. BONUS (500): Explain why.
500
Compare our moon to Io (a moon of Jupiter). Which moon would have a greater orbital speed. Why?
What is Io because Jupiter has more mass than Earth.
500
Draw and label the lunar phases.
What is diagram will be approved by teacher.
