Landscapes
What do you think of when you hear the word landscape ? You might think of plants and flowers. A landscape is the stretch Of land that can be seen from a place
The landscape in one area might be high and on a slope, or slant. The landscape in another area might be low and flat. It might be covered with trees or water. What is the landscape like around you?
I. Describe the landscape in the painting
. Circle an area on the painting that shows a slope in the landscape
10 EXPLAIN Module: Earth's Landscape
Maps
One way to show what the land is like is to make a map A map is a drawing of an area of Earth's surface. It can show you what the land and water are like in an area
Scientists Use Maps
Many scientists depend on maps. They use maps to organize information and to share information with others
Look at the map below. It shows what the land is like in different areas. The rough, tan areas show high land. The smooth, yellow and green areas show low land
Land surveyors collect data about the shape, location, and height of land. They measure pieces of land to draw boundaries. The information they find helps people decide where roads or buildings will go. Land surveyors also use their measurements to help make maps
A Famous Land Surveyor
George Washington was the first president of the United States Did you know he was also a land surveyor ? He made the map on the next page. It is a map of his farm in Virginia
ELABORATE Module: Earth's Landscape PRIMARY SOURCE These are the Ws that George Washington used as a land surveyor
I. Describe the landscape of George Washington's farm
Extend It
You are a land surveyor. Your job is to find the best place for a new airport in your town. Look at a map of your town. Identify an area that would make a good place for a new airport. What would the land look like
Draw a map of the area. Include a compass rose, map key, and syrntXIs. Use words and pictures to describe the landscape
KEEP PLANNING

Sience Challenge
Now that you have learned about maps and your local landscape, go to the Module Project Planning pages
The Sierra Nevada
A mountain range is a group of mountains. The Sierra Nevada is a mountain range that can be found in the Western United States. It is over 600 km (400 mi) long and nearly 100 km (70 mi) wide. This range is massive
The highest peak in the Sierra Nevada is Mount Whitney. Its summit is the third highest point in the United States. Throughout the mountain range there are many landforms. Yosemite Valley is a canyon. A canyon is a deep valley with very high, steep sides. It was formed by glaciers millions of years ago
Landforms on a Map
Some maps show high and low areas of land. This map of California shows where landforms like mountains and plains are located
Look at the colors on the map. Smooth, green areas show where land is low and flat. Rough, brown areas show where
W/here can you find mountains and plains in California land is high and on a slope
. Mt. Whitney is the tallest landform in California. Find out where it is located Label it on this map
. Circle an area on the map that shows mountains. Put an on an area that shows plains
Look at the map and use what you have learned. What patterns do you observe about where landforms are found in California
Lake Tahoe is also in the Sierra Nevada It is North America's largest alpine lake, or lake that is high in elevation
The Sierra Nevada stretches over such a large area that it includes three national parks: Yosemite, Sequoia, and Kings Canyon. These parks contain many valleys, meadows, rivers, and giant sequoia trees. Look at the photo of Mount Whitney. How could you use a pattern to describe what you observe
INQUIRY ACTIVITY
Hands On
Moving Water
Investigate what can cause water to move over a landscape
Make a Prediction How does water move over a landscape
Carry Out an Investigation
Build a landscape with different landforms Include a mountain and a valley in your landscape
. Place an ice cube at the top of the mountain
. Wait five minutes. Observe what happens
. Record your observations
Talk About It
Where does the water from the melting ice go
Mountains, Hills, and Valleys
The tallest kind of landform on Earth is a mountain. Mountains often have a pointed top and steep sides. Hills are mounds of land and rock. They are tall, too, but they are not as tall as mountains
A valley is the low land between two mountains or hills. A valley can be deep and narrow or long and wide
. What symbols could you use to show mountains, valleys, and hills on a map Draw and label them here
Revisit the Page Keeley Science Probe earlier in the lesson. Has your thinking changed ? If so, explain how it has changed
20 EVALUATE Module: Earth's Landscape
Three-Dimensional Thinking
I. Look at the map below. Which sentence can you tell is true by reading the map
A. Ted lives on a hill
B. Ted lives west of the pond
C. The land around Ted's has grass
D. The land south of Ted's school has trees
. Ted wants to make a model of the map. How can Ted show that he lives on a hill
INQUIRY ACTIVITY
Hands On
OPEN INQUIRY
Earth's Land
Think about the local land you explored in Lesson I. Look at the photos of land on Earth. Choose one photo and make a model of the land
Ask a Question What question will your model help you answer
Make a Model
BE CAREFUL Wear safety goggles
. Look at the photos of different land and water
. Place the aluminum pan on a table or the floor
Use the photo as your guide. Make a model of the land in the aluminum pan using the clay
. Add water if needed
