True or False: The Earth's moon has layers.
True
True or False: The terrestrial planets include Jupiter and Saturn.
False
What is a star?
A star is a burning ball of gases.
Name one part of a telescope
eye piece, objective lens, reflecting mirror, finderscope, focus knobs, aperture, tube
How long is an orbit of Earth around the Sun?
365 1/4 days. 365 days is acceptable.
Name any 2 moons.
Answers may vary: Moon, Io, Phobos, Deimos, Europa, Io, Callisto, Titan, and others
Name the hottest planet. Why is it hot?
Venus because of the Greenhouse Effect
Describe how our Sun Print pages work. Be sure to tell us the type of radiation that changed it.
Answers may slightly vary. When you expose the paper to UV radiation, it chemically reacts and changes the color of the paper that is exposed. When an object blocks the radiation, it doesn't change the color of the paper where the UV is blocked.
Which type of telescope using lenses only.
Refracting telescope
What is the force that keeps us revolving around the Sun?
Gravity
Name 2 landforms found on the moon.
Answers may vary: mare, rills, mountains, craters, trenches
List the 8 planets in order starting with the one closest to the Sun.
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune
Why do we describe stars as having a Life Cycle?
Stars are "born" or created in nebulae and then they continually change as the burn up their fuel
and then run out of fuel and eventually they can cease to be.
Why might a space telescope give us clearer images than one on earth?
With no light pollution from cities and no interference from dust and reflected light on the atmosphere, space telescopes like the Hubble give us clearer images.
Who is the scientist who described the 3 Laws of Motion?
Sir Isaac Newton working around 1687
Why do astronomers think that the original astronauts' footprints might still exist on the moon?
Since there is no atmosphere, there is no weathering to erase the footprints.
Describe the Red Spot on Jupiter.
It is a giant storm that has been swirling around for 100's of years. It is getting smaller.
List which types of stars end up as black holes.
Very massive stars
Why do images get turned upside down with a lens?
The light beams are bent and refocused upside down.
Explain the Law of Inertia.
An object at rest stays at rest
An object stays in motion
unless a force acts upon it.
Name one mission that has studied the moon or landed on the moon.
answers may vary: Apollo missions
When you played the Galactic games, describe at least one thing that would change on a planet like
Jupiter.
With such a strong gravitational pull, you couldn't jump as high or far.
Describe the difference between a solar and lunar eclipse.
The order of the Sun, moon, and earth vary in the two types of eclipse.
Solar = Sun, Moon, and Earth
Lunar = Moon, Earth, and Sun
You can choose your question:
1) Name another type of telescope that is not using visible light.
2) Why are reflecting telescopes bigger than refracting ones?
1) X-ray, UV, IR, gamma ray, microwave, or radio telescopes
2) A reflecting telescope uses mirrors which can be made lighter and bigger than lenses.
Explain how the 2 of the 3 laws of motion are used in launching a rocket.
Answers vary
1st Law - a force is needed to move the rocket
2nd Law - a specific size force ( fights gravity) is needed to move the mass of the rocket a certain acceleration ( or speed )
3rd Law - an equal and opposite force, engines push downward and rocket moves upward
