Planets
Name the planets in order from the sun.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
A ball of ice, gas, and dust that can be seen streaking across the night sky - orbiting the sun.
Comet
Does gravity 'push' or 'pull'? Explain.
We are pulled by Earth's gravity towards its center.
Why does the sun appear larger than any other star?
We're closest to it.
Scientists create these to show how something looks or works.
A model
Of all 8 planets, which other one may be best suitable for life?
Mars
Where is the asteroid belt located?
Why does Earth stay in orbit around the sun?
The sun's gravity keeps Earth in orbit.
What are the two terms for the moon increasing and decreasing in size?
Earth moves in a ________ orbit around the sun.
Elliptical
What is the smallest planet in our Solar System?
Mercury
A lump of rock in space in orbit around the sun, that can occasionally break free.
Meteoroid
Why does a feather fall at a slower rate than a bowling bowl?
The mass of the feather is less than air resistance, therefore air resistance suspends the feather longer.
What is the moon phase called when you CANNOT see it in the sky?
New moon
Telescopes allow scientists to ...
See distant objects in focus.
Describe three reasons why Earth is perfectly suited for life.
Water, temperature regulation, oxygen/CO2 balance, food supply
"I was located once between Mars and Jupiter until I strayed to the outer reaches. I broke from its orbit and came crashing towards the Earth. People say I was responsible for the death of the dinosaurs."
Asteroid
Describe the role of air resistance when you drop a pencil and an eraser.
Air resistance will act upon both objects, however, the objects have more mass than air resistance so they'll hit the ground at the same time.
Describe the size of our sun compared to other stars.
Average
A running back was spun by a defender and continued running. In science terms, his 'spin' could be called a ______.
Rotation
Astronauts were discussing if it would be possible to stay in space for a 2-3 year period and live on Mars. They came up with a plan to have enough food, water, and even oxygen. However, what two other problems could make life difficult?
Radiation (cancer), muscle atrophy, gravity differences, etc.
The sun is a ball of hot gases. It is composed mainly of this element.
Hydrogen
Beatrice weighed 423 pounds on Earth. Would her mass be the same on Mars? Would she weigh more, less, or the same? Explain.
Beatrice would have the same mass anywhere. However, she would weigh less because Mars has less gravity than Earth.
Remember, weight is the total force of gravity acting against you.
Bootes, scorpio, ursus major, and orions belt are all examples of _______.
Constellations
Describe the time it takes for one rotation of the Earth AND one revolution of the Earth.
24 hours ; 365 days
