What type of eclipse is shown?
What type of eclipse is shown?
Solar Eclipse
What phase of the moon is shown? How much light will we see on the moon?
What phase of the moon is shown? How much light will we see on the moon?
New moon, we will see no light reflecting on the moon-the sky will be dark.
What type of eclipse is pictured?
What type of eclipse is pictured?
Lunar Eclipse-Earth is casting a shadow on the moon. This is the most frequently seen type of eclipse, because the Earth casts a bigger shadow.

What two forces combine to form an orbit?
What two forces combine to form an orbit?
Gravity pulling in-ward and inertia going in a straight line.
The force that makes things spin in a circle
The force that makes things spin in a circle
Centripetal Force
Explain what they mean by equal areas in equal intervals of time. How are those two areas equal? Where does the planet move the fastest? The slowest?
Explain what they mean by equal areas in equal intervals of time. How are those two areas equal? Where does the planet move the fastest? The slowest?
The size of the shaded area is equal, the planet travels a much larger distance when its closer to the Sun in the same amount of time as it takes to go a shorter distance when the planet is farther away from the Sun.
It does this because it is moving faster closer to the Sun as it experiences a stronger force of gravity due to the decreased distance to the Sun. Kepler's 2nd Law
What is the Period of Revolution? Which planet will have the shortest Period of Revolution? Which will have the longest? What's Earth's Period of Revolution? 
What causes all of this?
What is the Period of Revolution? Which planet will have the shortest Period of Revolution? Which will have the longest? What's Earth's Period of Revolution?
What causes all of this?
Period of Revolution-the time it takes to complete one orbit of the Sun. Mercury has the shortest, Neptune has the longest. Earth's is 365.25 days which explains why we have a leap year every 4 years to take into account the .25 of a day. The calendar mistake was fixed by Pope Gregory XIII (13th) and it's the reason the calendar is called a Gregorian Calendar.

Objects have shorter periods of revolution (they orbit faster) when they are closer to the Sun because the are pulled on more by the Sun's gravity as the distance is decreased between the high mass object (the Sun) and the lower mass satellite (the planet).
Explain how Gravity works-what are the two factors that influence it and how do they work?
Explain why you experience more gravity on the Earth than you do on the Moon talking about Mass.
Explain why you experience less gravity on top of a mount...
Explain how Gravity works-what are the two factors that influence it and how do they work?
Explain why you experience more gravity on the Earth than you do on the Moon talking about Mass.
Explain why you experience less gravity on top of a mountain than you do at the beach.
Gravity is based on mass the mass of the objects in question and the distance between them. As the mass of the objects increases (there is more of them) and the distance between them decreases (they get closer) gravity will increase.
You are more attracted to the Earth than the moon because the Earth has much more mass. But, the moon does pull on the Earth causing the tides in the oceans of the world.
You experience less gravity on top of a mountain because you are farther from the core of the Earth.
What's shown? How long would it take Earth to do this? What affect does this have on Earth? What tilt should be shown if this object were Earth?
What's shown? How long would it take Earth to do this? What affect does this have on Earth? What tilt should be shown if this object were Earth?
Rotation-it takes Earth 24 hours, this causes our day. The Sun doesn't actually come up or go down, we spin and see it more or less throughout our day. The Earth is tilted at 23.5 degrees which the Sun to travel across our horizon.
Explain the Doppler Effect and Red and Blue Shifts
Explain the Doppler Effect and Red and Blue Shifts
As an energy source gets closer to the observer, it will appear to become louder-a Blue Shift. It's not really louder, it just seems like it because of the decrease in wavelength.
As the energy source gets farther away, the wavelength will lengthen and it will appear to get quieter-Red Shift
What are the outer planets called? What are they mostly composed of? Why are they made up of this stuff?
What are the outer planets called? What are they mostly composed of? Why are they made up of this stuff?
Gas Giants-they are farther from the Sun and cooler so they have thick atmospheres of gas.
Explain the difference between mass and weight.
Explain the difference between mass and weight.
Mass is the amount of matter in an object. Weight is a measurement of gravity's pull on that mass. Mass will not change with location, weight will.
What do you call a big cloud of gas and dust?
What do you call a big cloud of gas and dust?
Nebula
Why does Venus look like a big fiery ball to observers?
Why does Venus look like a big fiery ball to observers?
It has a atmosphere made out of CO2 gas which is reflective and it reflects Sun Light. It is the planet that is closest in size to the Earth.
What do you call a Star and Everything that orbits it?
What do you call a Star and Everything that orbits it?
Solar System
Explain what Volume is
Explain what Volume is
The amount of space something takes up or the amount of space within the object
Explain what Density is
Explain what Density is
The amount of matter in a volume (space)
What season would it be in North America and why?
What season would it be in North America and why?
Summer-NA is tilted towards the sun
What season would it be in North America and why?
What season would it be in North America and why?
Winter, NA is tilted away from the Sun.
What do you call the process of building by smashing into things?
What do you call the process of building by smashing into things?
Accretion
Explain why Iron forms the cores of stars and planets
Explain why Iron forms the cores of stars and planets
Iron is the densest element that Stars can make by splitting the nucleus and recombining protons. The nucleus of Iron is too dense for stars to burn so the Iron sinks to the core of the star because of its large density. When stars explode they eject Iron into the Universe and this Iron collects because of gravity and forms the cores of planets.
Explain what the Universe is
Explain what the Universe is
Everything that exists
Explain what a satellite is
Explain what a satellite is
Anything that orbits-the low mass body will orbit the high mass body. The Earth is a satellite of the Sun, the moon is a satellite of Earth.
Explain what Inertia is and how it works
Explain what Inertia is and how it works
Inertia-the resistance of an object to a change in motion. An object sitting still will sit still and an object in motion will remain in motion until a big enough force is applied to change that sitting still or motion.
Explain what a planetismal is
Explain what a planetismal is
A young planet that is growing through accretion in an immature solar system. Aka a baby planet.
Explain the differences between and immature and mature solar system
Explain the differences between and immature and mature solar system
Immature-orbits not yet defined, lots of planetismals smashing into each other and acreting (growing by smashing)
Mature-defined orbits, little accretion, full size planets
Which planet is the largest with a giant Red Spot that actually a storm that's bigger than Earth?
Which planet is the largest with a giant Red Spot that actually a storm that's bigger than Earth? It also has the most moons as it produces the most gravity...
Jupiter
Which planet has all the rings?
Which planet has all the rings?
Saturn
Why is Pluto no longer considered a planet?
Why is Pluto no longer considered a planet?
It's not big enough-it turns out that it's actually a hunk of ice that orbits with a lot of other big chunks of ice in a system trans Neptune objects.
Explain what an Astronomical Unit is and where we use it to measure.
Explain what an Astronomical Unit is and where we use it to measure.
It's the average distance from the Earth to the Sun and we use it to measure inside of our Solar System.
Explain what a light year is and where we use it to measure.
Explain what a light year is and where we use it to measure.
It's a really big measurement-the distance that light will travel one year in space. We use it to measure large distances outside of our solar system, like the distance to stars other than our Sun or across Galaxies.
Why is Mars red?
Why is Mars red?
It's made of Iron and rusted.
Why can we see the light of the moon?
Why can we see the light of the moon?
It reflects light from the Sun.
