Ecosystems | Project Based Learning
Students will explore ecosystems by identifying living and nonliving parts and creating a simple classroom model of an ecosystem. The lesson uses a project-based approach so students learn by observing, discussing, and making a product together.
| Term | Definition |
|---|---|
| ecosystem | A place where living and nonliving things interact and depend on one another. |
| living things | Plants, animals, and other things that grow and need food, water, and air. |
| nonliving things | Parts of an ecosystem like water, rocks, sunlight, and air that are not alive. |
| habitat | The home of a plant or animal. |
| depend | To need something in order to live and grow. |
Show a picture of a pond, forest, or desert and ask students what living and nonliving things they notice. Record ideas on the board.
Look closely, share observations, and name things they see in the picture.
Explain that an ecosystem includes living and nonliving things that work together. Model sorting a few examples into living and nonliving categories.
Listen, answer questions, and help sort examples.
Tell students they will work in small groups to create a paper model of an ecosystem such as a pond, forest, desert, or grassland. Show a quick example and explain expectations.
Choose a group ecosystem and discuss what should be included in the model.
Circulate, ask guiding questions, and support students as they draw, cut, label, and arrange parts of the ecosystem model.
Work in groups to create their model and label at least 3 living and 3 nonliving parts.
Invite a few groups to show their models and explain how the parts in the ecosystem work together.
Present their model and listen to classmates' ideas.
Review the key idea that ecosystems need both living and nonliving parts. Ask students to complete a quick oral or sticky note reflection: 'One thing I learned is...'
Share one fact or write a short reflection.
Review the big idea: ecosystems are made of living and nonliving things that work together. Celebrate the completed models and remind students that every part of an ecosystem matters.
