The Sun
True or False: The Sun is the biggest star and that is why it appears to be so large in our sky.
FALSE: It is the closest star to us, that is why it appears to be so large.
True or False: Gravity is a pushing force.
FALSE: Gravity is a pulling force.
What does the Earth rotate around?
The axis! An imaginary line that runs from the North Pole to the South Pole.
How much of the Earth is ALWAYS lit by the Sun?
Always HALF!!
How much of the Moon is lit by the Sun?
Half of the Moon is lit by the Sun.
True or False: There are stars that are bigger and brighter than our Sun in the Milky Way.
TRUE
What does Gravity pull objects towards?
Earth's center!
What does the Earth revolve or orbit around?
The Earth revolves around the Sun. This orbit is an elliptical (oval) shape!
Why do we have nighttime if the Sun is always shining?
The Earth is only half lit at all times, and rotating on its axis so when it rotates into the darker half it is nighttime.
Describe a waxing crescent.
Getting larger; less than half is lit up on the right side.
Why does the Sun appear to move across the sky?
The Sun is not moving, the Earth is rotating around the axis so it appears as though the Sun is moving across our sky.
True or False: Gravity pulls objects towards the North Pole.
FALSE: Gravity pulls objects towards the Earth's Center
What motion (rotation or revolution) makes shadows appear to be long AND short?
Earth's rotation: Earth's rotation around its axis makes the sun appear to move across the sky. When they sun is at different places in our sky, it creates different length shadows.
When the moon is in between the Earth and the Sun what do we see from Earth? (Try drawing it!)
A New Moon!
What shape is the Earth?
The Earth is a sphere
What does the rotation of Earth around its axis cause? AND How long does this take?
Earth's rotation around its axis creates night and day and takes about 24 hours.
True or False: The Moon produces its own light.
FALSE: The light you see is sunlight reflecting off of the Moon!
What object has more gravitational pull: a bowling ball or a tennis ball?
A bowling ball because it has more mass!
What does the revolution of the Earth around the Sun mixed with the Earth's tilt cause? AND about how long does one revolution take?
Earth's revolution around the Sun mixed with the tilt of the Earth creates a year and seasons. This takes about 365 days.
