Earth and Moon
Identify the phase of the Moon when it looks like a full circle.
Full Moon
Neptune, Saturn.
Name something these have in common.
They are outer planets, or gas giants
Definition- totally see thorugh. LIght rays travel uninterrupted through an object
Transparent
This is the measure of how loud or soft something is.
Volume
Stars appear to do this in the night sky, but it is not real! It's due to the atmosphere. The light rays travel through air particles and other matter and they briefly interrupt the light rays from reaching our eyes.
Twinkle
Describe why day and night occur on Earth.
Earth rotates on an axis. 12 hours of the day we face toward the sun; 12 hours a day we face toward darkness.
This object in the sky creates its own light. It does not move.
A star, or our sun
This is defined as light rays bouncing off of an object and then traveling in another (usually opposite) direction
Reflection
Defined as how high or low a sound is.
Pitch
Light does NOT need this to be seen.
a medium (matter)
Light can travel through a vacuum- this is evident with space photography!
This is 365 days long. It is also known as one year.
(Technically 365.25 days)
What is one revolution?
List these objects in order of size, from largest to smallest: Earth, the Sun, the Moon
Sun, then Earth, then Moon
This object separates light into its different wavelengths. It creates something beautiful.
a Prism
To increase this, add more energy into the sound. Hint: give the scientific name for the measure of the wave)
Amplitude/ volume
Why does a train sound louder as it gets closer to us?
The amplitude of the sound waves are largest when close to the source. The sound waves lose energy (amplitude/volume) as the source and the ear get farther apart.
Definition: to shrink or decrease in size, especially when related to phases of the moon.
What is waning?
This is the season when the Northern hemisphere is tilted toward the sun, and in our ellipse-shaped revolution we are nearest to our only star.
Summer
Martin notices that only some light goes through a paper towel when he holds a lightbulb nearby. How can he classify?
Translucent
Sound travels fastest through...
Solid
When the southern hemisphere is tilted toward the sun, what season do we experience in the northern hemisphere?
Winter
The phases of the moon, in order.
New Moon
Crescent
Quarter
Gibbous
Full
And then back again in reverse to complete the lunar cycle
What is the name of the bunch of floating rock and ice that separates the inner and outer planets?
Asteroid belt
If all the light energy except blue rays are absorbed, what color does an item appear to our eyes?
Blue- the blue is the only thing that bounces back if everything else is absorbed.
This is required for sound to be heard
A medium (matter!)
This is the order of the planets, from innermost to ourtermost.
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
