Terms
An imaginary line that passes through passes from the North Pole, through the Earth’s center, and to the South Pole.
Axis
The force that attracts all objects towards each other.
Gravity
In what month in the Northern Hemisphere gets the most amount of Sunlight?
June
What are the two ways Earth Moves?
Earth rotates and reevolves
The spinning of Earth on its axis.
Rotation
Every object in the universe attracts each other every other object.
Law of Universal Gravitation
In what month does the Southern Hemisphere get the least amount of Sunlight?
June
What causes the seasons?
The Earth tilt and revolution.
The movement of one object around another.
Revolution
The tendency of an object to resist a change in its Motion.
Inertia
Does the South Pole receive sunlight in June (yes or no).
Yes
What are the directions the Earth rotates
East to West.
The Earth's path around the sun.
Orbit
Bill is conducting an experiment based on Isaac Newton's law of universal gravitation. He is testing the strength of the force of gravity between two objects.
Distance between the objects.
The day the Sun is highest in the sky. The solstice happens when the Northern and Southern Hemisphere is at their strongest tilt toward the sun.
Solstice
The line that goes across the earth.
Equator
________ is to give a possible but not yet proven explanation for something.
Hypothesized
Sarah reads about how astronauts appear to be weightless in space. She wonders how Earth stays in orbit around the sun when astronauts float while in orbit around Earth. She remembers that there is a force that keeps Earth in orbit around the sun. This force is the same force that keeps astronauts in orbit around the Earth. It also helps to explain why they appear to be weightless. What is this force?
Gravity
Halfway between the solstices, neither hemisphere is tilted toward the sun. The day and night are both 12 hours
Equinox
What are the names of the poles?
