Lesson 1: California's Geography

In this Grade 3 lesson from California myWorld Interactive, students learn about California's physical geography, including key landforms such as mountains, hills, valleys, and deserts, as well as the state's major bodies of water and ecosystems. Students explore vocabulary terms like elevation, range, and irrigate to understand how these natural features shape the land and support both farming and wildlife. The lesson builds map awareness and helps students connect California's diverse physical features to everyday life in their own communities.

Section 1

Geographers Study Earth's Natural Features

Key Idea

The study of Earth's natural features and processes is called physical geography. It focuses on the planet's land, water, plants, and animals, rather than on the countries or cities that people have created. Understanding these natural elements helps explain why a place looks and functions the way it does.

Physical geographers examine different types of landforms, which are natural shapes on the Earth's surface like mountains, valleys, and coastlines. They also study bodies of water, such as rivers and oceans, and the ecosystems, or communities of living things, that exist in these different environments.

Section 2

Landforms Shape Our Community

Key Idea

California has many different kinds of landforms, and your community is built on one of them. Some towns are located near the coast, where the land meets the huge Pacific Ocean. Others are in the large, flat Central Valley, or near tall mountains like the Sierra Nevada. There are even communities in hot, dry deserts.

Water is also a big part of California's geography. Rivers flow down from the mountains, carrying water across the land to lakes and the ocean. These physical features are made by nature, not by people. By looking outside, you can see if you live near hills, flat plains, or water, and identify what makes your region special.

Section 3

California's Regions: Where People Settled

Key Idea

There are four main natural regions in California: the mountains, valleys, deserts, and the coast. When people first came to settle California, they looked for the best places to build their homes and start new lives.

Many settlers chose the coastal region. It offered mild weather and easy access to the ocean for fishing and travel. The steep mountains and hot, dry deserts were much harder places to live. Because of these early choices, most of California's largest cities grew along the coast.

Section 4

People Bring Water to Dry Land

Key Idea

People in California need water for many things. It is used to drink and to have fun in lakes and rivers. Farmers especially need water to grow fruits and vegetables in dry places like the Central Valley.

To get water to their farms, people built canals and pipes. This helps them irrigate the land, which means giving water to crops. Sometimes, there is not enough water for all the farms and all the cities. This creates a big challenge for everyone in California.
