Put the following in order of decreasing magnitudes:

city, universe, house, galaxy, state, solar system, planet, continent,

Universe, galaxy, solar system, planet, continent, state, city, house

Objective: understand the size and scale of the universe

Success Criteria:Be able to:

describe the size of the universecompare stellar objects based on their relative size

Study of space

Big Idea: How is mass/energy conserved and transformed in space?

What is in each of the following “containers”

Universe- Galaxy- Solar System-

Stars, planets, dark matter, elements, energy, galaxies, solar systems, constellations, comets, asteroids

Read over the questions, as you watch the video think about the parts that you will need to answer the questions, write yourself some notes to be able to do that without having to pause the video

Why is looking at starlight really a look at the past?

If a star ceases to exist when would we know about it? Justify based on your background knowledge and answer above.

Why is communication with and travel to other galaxies so difficult? What implications would this have on determining if there is extraterrestrial life?

We jump by a factor of 100in each frame. This also shows the context of the Earth in the Universe.

Something creative…A drawing, a diagram, a question, a sentence that represents your thinking from this class period.

I own this: I still don’t understand this:

Describe how you would have to send a message to someone in another galaxy? What things would you need to consider and what would make this difficult?

Explain the size of the solar system in relation to the Milky Way Galaxy. Explain in terms of the universe.

What makes the universe operate the way it does? (why do planets orbit around the sun, why does the Milky Way orbit around itself, what keeps things from crashing into each other, why do they move at all, etc.)

We can compare different scales by using ratios or proportions (comparing fractions)

Units on denominator do not have to equal units on the numerator, but comparisons must be set up to be equal.

scale (in) = scale (in) actual (ft) actual (ft)

If the Earth were the size of a globe, how big would Mercury be?

Given information Earth’s diameter= 8000 miles Globe’s diameter (scaled Earth)= 12

inches Mercury’s diameter= 3032 milesFind:Scaled Mercury= ???

Scaled Earth (inches) =

Actual Earth (miles)

Scaled Mercury (inches)

Actual Mercury (miles)

12 inches =

8000 miles

? Inches

3032 miles

? = (3032 x 12) / 8000

? = 4.5 inches

If the earth were the size of a globe, how far away would Mercury be?

Given information:Earth’s diameter= 8000 miles Globe’s diameter (scaled Earth)= 12

inches Mercury’s distance= 57,000,000 milesFind:Scaled Mercury= ???
