Earth-Sun-Moon
When the northern hemisphere is tilted away from the sun, which season will it be?
Winter
The distance that light travels in one year (~5.88 trillion miles)
All stars are born in a _________.
nebula
Which formed first- the sun or the Earth?
Sun
When you see a shooting star in the sky, what you are really seeing is a ________.
Meteor
What causes tides?
What are the three types of galaxies?
Spiral, elliptical, and irregular
What color star is the hottest and brightest?
Blue
How many stars are in our solar system?
One (the Sun!)
What is a black hole?
A region in space where gravity is so strong that nothing can escape, not even light.
Which moon phase is missing from this sequence?
Full Moon, Waning Gibbous, __________, Waning Crescent
Third Quarter/Last Quarter
What is the reason that galaxies can exist? In other words, how are billions of solar systems held together to create a galaxy?
Gravity
What are stars mainly composed of?
Hydrogen and helium
What are asteroids?
How do mass and distance affect the strength of gravity?
Describe or draw the position of the Earth, Sun, and Moon during a lunar eclipse.
During a lunar eclipse, the Earth will be in between the sun and moon, blocking out the Sun's light and casting a shadow on the moon.
Where is our solar system located within the Milky Way Galaxy?
Most stars in the universe (90%) are ______ _________ stars.
main sequence
Jupiter
Why are scale models important to use when learning about space?
Scale models are important to use when learning about space because space is so big that it is hard to comprehend the true sizes of objects or the distances between them.
Scale models help us visualize the sizes and distances of objects in space by using more manageable numbers.
Describe the cause of the seasons in detail.
The seasons are caused by Earth's tilt as it moves around the sun. Earth is tilted away/toward the sun at different positions because of its 23.5 degree tilt, causing the seasons.
Why are elliptical galaxies generally less bright than other types of galaxies?
Elliptical galaxies are less bright because they mainly contain low mass stars. Low mass stars are less bright than high mass stars.
List the life cycle of a low to medium mass star from beginning to end.
Nebula, protostar, main sequence, red giant, planetary nebula, white dwarf
Earth is often called the Goldilocks Planet because....
It has the perfect conditions to sustain life. It is not too close or too far away from the sun, so the temperatures are suitable for life, and water is able to exist in a liquid state.
Draw and label a model that shows either a star, planet, galaxy, or moon being formed.
Then, the drawing should show that the material is being drawn toward each other due to the force of gravity.
Finally, accretion continues until the object is formed. Therefore the last part of the drawing should show the "final product."
