cameron,Greytown

I think it would take 18 months to drive round the earth
15 years to drive too the moon
25 years too venus
65 years too the sun
100 years to pluto

Kaden, Greytown

I think it would take 2 years to drive around the world
20 years to drive to the moon
40 years to drive to Venus
80 years to get to the sun
120 years to Pluto

Madison, Greytown

I think it would take 1 year to drive round the earth
5 years to get to the moon
12 years to get to venus
30 years to get to the sun
100 years to get to pluto


Sophie, Greytown

I think it would take 10 months to drive around the world
3 years to get to the moon
4 years to get to Venus
8 years to drive to the sun
20 years to get to Pluto.


Emma, Greytown

I think it would take 6 months to drive around the world
1 year to get to the moon
1 year and 6 months to get to Venus
5 years to drive to the sun
and 10 years to get to Pluto.

However, as we all know, you can't exactly drive to pluto, you'd have to take a rocket. And if you traveled to Pluto in a rocket I'm guessing it would take three or four months.

Week One Day 4

Now it is time for our walk. Download this and make a couple of copies.
Put your reflections after this. One will be your estimate as to where you would drop the nearest star and the other will be your wondering about what you have just done.

Lexi, Martinborough

Wow I can’t believe how tiny the earth is in comparison to the huge sun! Pluto is so tiny and so far away! It is amazing!


Matthew, Greytown


If I was traveling in a car a 100kmph how long do I think it would take to travel....
Around the earth= 1 year and 2 months
To get to the moon= 3 years and 7 months
Venus(our nearest planet)= 8 years and 4 months
The sun= 15,000 years and 6 months
Pluto= 246,396 years and 3 months

If I was traveling in the fastest rocket known to man( it goes 40,000kmph) how long do I think it would it take to travel.......
Around the earth= 1 hour
To get to the moon=3.5 hours
Venus(our nearest planet)= 18.3 hours
The sun=259days and 6 hours
Pluto= 1 year and 354 days


Josie, Greytown


In a car...
How long to go around the Earth once? 3 and 1/2 years
How long might it take to get to the moon? 1 year
Venus our nearest planet? 2 years
The sun? 300 years

In a rocket...
How long to go around the Earth once? 1/2 an hour
How long might it take to get to the moon? 1 hour

Week 2 Day One - Moon / Outer planets

Put your answers after each section.

The Outer Planets
Throughout most of human history, only six planets have been known: Mercury, Venus, Earth, Mars, Jupiter, Saturn. (Most of the time nobody knew what planets were or that the Earth is a planet.) Then, in the last three centuries, three new planets were discovered. Uranus, though theoretically visible to the naked eye on fine nights if you know just where to look, was not noticed till 1718. Neptune was discovered by careful calculation and search in 1846, and Pluto in a similar way, but not till 1930 after a quarter of a century of meticulous search, for even in large telescopes it is lost among countless thousands of equally faint stars.
And anyone who takes your planet-walk will say: "No wonder!"
The Moon
On our scale model the moon is about 5.5 centimetres from the Earth.
Using the model put a moon down beside the Earth. This Moon will have to be another pinhead (theoretically between the sizes of Mercury and Pluto).
Look down on this distance, the length of your thumb. This is the greatest distance that Man has yet leaped from home. Reflect on the manned mission to Mars now being suggested (14 paces / metres in our model) or the trips proposed in science fiction: to Jupiter as in the film 2001 Space Odyssey (109 paces); to the nearest star (seven thousand kilometres in our model); to the Andromeda Galaxy (half a million times farther again).
Find out some information about manned trips to the moon.

Week 2 Day Two The Oort cloud / Space

Greater Distances
The solar system does not really end with Pluto. Besides the planets, there is a thin haze of dust (some of it bunched into comets). Any of this dust that is nearer to the Sun than to any other star may be held in the gravitational field of the Sun and so counts as part of our solar system. So the outermost edges of this may be half way to the nearest star.
On the scale of our model, Pluto is one kilometre out. But the true limit of the solar system (in our model) is four thousand kilometres out. How far away is that? There is a lot of nothing out there especially if we think of it as a very large ball.

Do some research on the Oort cloud
You might start here http://en.wikipedia.org/wiki/Oort_cloud

The Emptiness of Space
It is hard to understand how the sun’s gravitational attraction holds the planets in orbit over such huge distances. Mainly this is because in our model there are all sorts of other things, buildings, trees, people etc. In space there is NOTHING – it is empty pretty much.
It is only because space is so empty that the Sun is the nearest important gravitational influence on the Earth.
Write your wonderings?

How far have things gone?

Have a think about space travel. What would you need? Where might you head? Why? Have a look at http://imagine.gsfc.nasa.gov/docs/ask_astro/answers/980224b.html
http://en.wikipedia.org/wiki/Voyager_1
and think about it. Why does it take 14 hours for the signals to reach Earth? What would it be like if you were light years away?
