Mixed Bag
This is where the sky appears to meet with the surface of the Earth.
What is the horizon?
When the sun appears low in the sky, the shadow it casts is short or long?
What is long?
The moon orbits the Earth. This means that it is a natural one of these.
What is a satellite?
The measure of the luminosity (a measure of light) of a star as seen from Earth (a combination of luminosity and distance). How bright a star "appears" from Earth.
What is apparent brightness?
The curved path in which a planet, satellite, or spacecraft moves around another body.
What is orbit?
Scientists use observations to make these.
What are predictions?
When the sun appears high in the sky at noon or midday, the shadow it casts is short or long?
What is short?
The moon takes about this amount of time to orbit the Earth.
What is about 29 days?
A group of stars in the sky that form a pattern in the shape of an animal, object, or person.
What s a constellation?
To turn around on an axis.
What is rotate?
These are important in studying science. They simplify complex phenomena. They help us visualize and understand concepts that would otherwise be difficult to grasp. They are a physical or visual representation.
What are models?
The Earth takes this amount of time to orbit the sun.
What is one year? OR
What is 365 days?
The name of the time period in which the moon makes one full revolution around the Earth.
What is a lunar month?
A unit of distance equal to the distance light can travel in one year through empty space, about six trillion miles.
What is light year?
A dark image cast on some surface by an object blocking the light of the Sun or another source of light.
What is a shadow?
The cause of day and night.
Earth's rotation on its axis every 24 hours. Facing the sun (day), facing away fro the sun (night)
The Earth makes one full rotation on its axis in this amount of time.
What is 24 hours? OR
What is one day?
When the dark side of the moon is facing the Earth - the name for this moon is this.
What is New Moon?
The Sun and Betelgeuse are two stars in the sky. the Sun is only 8 light MINUTES away. Betelgeuse is 642 light YEARS away. Betelgeuse is much larger and much brighter than the Sun. Which one of these two stars APPEARS larger and brighter to us on earth and why.
What is the Sun appears larger and brighter EVEN though Betelgeuse is much brighter and larger because the Sun is MUCH closer. So its apparent brightness is MUCH brighter.
A round, solid figure in which every point on the surface is an equal distance from the center (example: a round ball).
What is a sphere?
A moon that appears smaller each night as it moves from being fully lit (full moon) to completely dark (new moon) is said to be doing this.
What is waning?
If a ball is thrown up into the air, how will it fall?
What is straight down toward Earth?
The first phase after the New Moon, where the light is growing is called this kind of crescent moon
What is the waxing crescent moon?
The sun is a star that appears larger and brighter than the other stars True or false? Explain why
What is that the Sun appears larger and brighter than other stars mainly because it is much closer to Earth, so its light and apparent size are far greater from our vantage point.
The force by which all objects in the universe are attracted to each other (on Earth, this force pulls objects to the center of our spherical planet)
What is gravity?
