CHAPTER FOUR

MARIA:
Here is a photo my Great Grandfather took years ago. Amelia, take this photo and see if you can you find where they are from?

AMELIA:
Hello, sir. Do you know where this picture was taken? It is an old photograph taken with a pigeon camera. IÕm on a mission to take a picture of what it looks like now.

STUMPY:
Ah. Yes. MMm, hmmm. I know where your picture was taken. IÕm putting together a scrapbook of old pictures of Battery Park that IÕve collected through the years. Come aboard and weÕll have a look.

You have an old picture alright. This is Battery Park. Your picture was taken back when the Brooklyn Tunnel was being built. The park was closed for about 10 years while they built the tunnel. This was just one of many changes in the park.

This is a painting of Castle Clinton. It was built almost 200 years ago out on an island.

AMELIA:
If it was built out in the water, how did people get to it?

STUMPY:
They built a long bridge to get from the shore out to the castle. Do you see the skinny line in the picture here?

AMELIA:
But there is no bridge in my picture. What happened? Did people move Castle Clinton onto the land?

STUMPY:
Much has changed over the years.

People dumped rocks into the water around the castle and soon there was enough land you could walk to the Castle. The bridge is gone.

AMELIA:
Wow, what a change. But where did they get the rocks and dirt? STUMPY: Well, from the buildings of course. Big holes were dug to begin building these great skyscapers. The bigger the building the bigger the hole. So, all the rocks and dirt came from the big holes.

Why did they have to build so many buildings?

STUMPY:
Years ago my grandfather told me about all the people who came to our country to live. More people meant more places to live, work, shop, and eat. My grandfather used to sail the ships from across the ocean bringing more people to America. We call them immigrants. Do you know what immigrants are?

AMELIA:
Well, not really.

STUMPY:
Immigrants are people who move from other countries to come live in our country. Back A hundred years ago, thousands of immigrants arrived in America EVERY day.

AMELIA:
Wow. It looks REALLY different today.

STUMPY:
Castle Clinton is now called Castle Gardens and it is museum in Battery Park. The museum shows the many pictures of how the land changed over time. My father, my grand father, and even my great grandfather have been sailing ships in this harbor for years. I would like to make a scrapbook of pictures. That is why I am I am putting these old pictures in a scrapbook.

AMELIA:
Could I help you?

STUMPY:
What a wonderful idea. Maybe together we put the pictures in order and see the changes over time.

Chapter 4: Interaction A

1. Background in keeping with scrapbook theme 2. 4 images of Battery Park through the years 3. Stumpy (head shot) 4. Four Spaces to sort images into

IMAGES: Four images of Battery Park 1. Clinton "1851 - Library of Congress map 2. 1870 - Castle Garden (2nd one show on web site) 3. 1995 - satellite image 4. 2000 IKONOS

DESCRIPTION OF INTERACTION:

Directions:

STUMPY: Help me put the pictures in order from oldest too newest.

End of Chapter 4: Interaction A
Thank you Amelia. Now I can show everyone my scrapbook!

AMELIA:
That was fun. Now I know where to take my picture. I will fly over Castle Clinton. Thank you for showing me how things have changed over time. It was nice to meet you. Bye.

STUMPY:
Bye Amelia. Be sure to fly up really high to get a picture of the whole park.

MARIA:
Great photo, Amelia. But it looks so different from the one my grandfather gave me.

Talk with NASA Scientist

MARIA:
Hello Dr. Susan, I was wondering if you could help me learn about another photo from my pigeonÕs camera.

SCIENTIST: Hi Maria, good to hear from you again. IÕd be happy to help.

MARIA:
The old photo looks so much different from the new one from Amelia. Why is it so different?

SCIENTIST:
This is what happens over time, Maria. Let me show you what happened in Jamaica Bay.

SCIENTIST:
The islands in Jamaica Bay have changed over time. Satellites help us to see this change that happened slowly over a long period of time. Change is hard to see each day but if we look at pictures we can see changes that are very slow. As, water washes away land from the islands in Jamaica Bay, they slowly get smaller. [is it possible to highlight Ñ with color or even cropping in Ñ on an island that is eroding? Do this as Susan is talking.]

With satellites, we can look at our more of our Earth.

We can see changes that are hard for us to see from the ground. Like clouds moving.

MARIA:
I didnÕt know satellite images were used in so many ways.

SCIENTIST:
There are many other ways we use satellites. But before scientists could use these images, we needed to learn what we are looking at to use these satellite images. Would you like to learn how to READ a satellite image?

MARIA:
Oh Yes. I would love to learn!

SCIENTIST:
Lets look at another image of New York City. We can see small skinny lines that go strait, turn and curve along the ground. These are roads. When one of these lines goes over the water, that is a bridge. [while talking, animate orange line for roads going across image] Large strait lines are sometimes airports [animate orange lines over top runways at LaGuardia Airport (far right)]. Look at the rectangles, squares and curved shape next to the runway. [highlight the buildings next to airport Ñ indicated in red here but can use any color or technique to highlight] Those shapes are buildings next to the runway. The green rectangle in the city is a park. [highlight central park] The really dark area is water. The land out in the middle of the water is an island. There are many islands around New York City. [highlight islands]

SCIENTIST:
Now you try to find places in the city on a satellite image.

Chapter 4: INTERACTION B


IMAGES: 1. Image of NYC 2. Roll-overs for 6 types of features : water, park, lake, island, clouds, bridges 3. Shapes (solid color or cut-outs from sat image) that match the 6 types of features

DESCRIPTION OF INTERACTION:

Student is asked to match the shape of the feature on the side of the screen, with the feature in the image. A kind of I SPY where the student and drag and drop the shape onto the satellite image. Each shape is introduced one at a time accumulating along the side (or across the top) as each shape is found.

Each shape is introduced separately. When Shape appears on the side of screen, SCIENTIST gives instruction and the Shape is highlighted.

Water Directions: "Find the water in the Satellite image?" Correct match: "You are right! The river looks like a squiggly line." Incorrect match or help: "What shape do you think a river is?"

Park Directions: "Find the park in the Satellite image?" Correct match: "way to go" "There is GREEN grass and trees in the park." Incorrect match, "What color do you think a park is?"

Lake Directions: "Find the lake in the Satellite image?" Correct match: "way to go" "A lake is water surrounded by land" Incorrect match: "A lake is water surrounded by land?"

Island Directions: "Find the island in the Satellite image?" Correct match: "way to go" "Islands are land surrounded by water" Incorrect match: "What do you find all around an island?" or "where do you think an island might be"

Bridges Directions: "Find the bridges in the Satellite image?" Correct match: "way to go" "Bridges look like lines going over the water" Incorrect match: "What shape do you think bridges are?"

When all are matched correctly: [video of scientist returns]

End Of Chapter 4: INTERACTION B


SCIENTIST:
Now you can read a satellite image! You can be a great scientist.

MARIA:
Thank you Dr. Susan. I will think about being a scientist. I DID have a lot of fun looking at the satellite images.

SCIENTIST:
Bye Maria!

MARIA:
Bye Dr. Susan
