Ecosystems in Balance

3rd Grade Oral Language Resources

Content Objectives

Students will:

• Learn about the concept of ecosystems in balance.
• Access prior knowledge and build background about ecosystems
• Explore and apply understanding of the concept of ecosystems by thinking about ways to protect nature.

Language Objectives

Students will:

• Demonstrate an understanding of ecosystems.
• Orally use words that identify different parts of the ecosystem.
• Extend oral vocabulary by discussing ways to protect ecosystems.
• Use key concept words [ecosystem, plants, animals].



• Use the slideshow to review the key concept words.
• Explain that students are going to learn about ecosystems in balance:
• Ecosystems are made up of all the living and non• living things in a given area.
• Destruction of wildlife is dangerous to ecosystems.
• There are ways to help maintain the balance of ecosystems.


• After the host introduces the slideshow, point to the photo on screen. Ask students: What do you see in this photograph? (trees, grass, a park, the sky, buildings, plants, and so forth).
• Ask students: Can you name some of the living things that make their home in this area? (birds, plants, trees, insects, people, flowers, and so forth).
• Say: Ecosystems are made up of all the living and non• living things in a certain area. Ecosystems provide homes, food, and life to many plants and animals. How can we protect ecosystems? (don't litter, clean them up, etc.)

Guided Practice

• Guide students through the next three slides, showing them different parts of ecosystems. Always have the students discuss how living in these ecosystems is different from the environment they live in.


• Play the games that follow. Have them discuss with their partner the different topics that appear during the Talk About It feature.
• After the first game, ask students to think of an animal they might find in nature and discuss where it lives and what kind of food it eats. After the second game, have them discuss ways they might help to keep ecosystems in balance.


• Ask students: Why is it important to protect the Earth's ecosystems?
• Summarize for students that ecosystems are home to living and non• living things. It is important to keep ecosystems in balance. Encourage them to think about why it is important to keep ecosystems in balance.
