Ecosystems | Project Based Learning
Students work in teams to design, build, and test a simple robotic model of an ecosystem that responds to changing conditions such as light, temperature, moisture, or movement. Through project-based learning, students connect robotics to ecosystem needs, interactions, and balance.
| Term | Definition |
|---|---|
| ecosystem | A community of living things and nonliving parts that interact in an area. |
| organism | A living thing, such as a plant or animal. |
| sensor | A part of a robot that detects information from the environment. |
| prototype | A first model made to test an idea. |
| balance | A condition in which parts of an ecosystem work together and stay stable. |
| adaptation | A trait or behavior that helps a living thing survive in its habitat. |
Show an image or short clip of a forest, pond, or desert ecosystem. Ask: What living and nonliving parts do you notice? What might happen if one part changes?
Observe, discuss, and identify organisms, water, light, soil, air, and other features.
Explain the challenge: teams will create a robotic ecosystem model that reacts to an environmental change and shows how that change affects the habitat. Review the criteria and success looks like a model that includes at least one sensor or programmed response, a labeled ecosystem element, and a clear explanation.
Listen, ask questions, and review the project goal and criteria.
Provide the planning sheet and assign teams roles if needed. Prompt teams to choose an ecosystem and decide what their robot will represent or control, such as a watering system, moving animal, or light response.
Sketch ideas, choose an ecosystem, assign roles, and list materials needed.
Circulate to support teams with construction and coding. Ask guiding questions: What does your sensor measure? What should happen when the environment changes? How does your model show ecosystem balance?
Build the model, connect sensors if available, and program a simple response.
Ask teams to test their prototype using one environmental change. Encourage debugging and redesign based on results.
Test the model, record what works, fix problems, and improve the design.
Invite quick team presentations. Ask each group to explain the ecosystem, the change they modeled, and how the robot responded.
Present the prototype and explain how it represents ecosystem interactions.
End with a brief class discussion: What did your robot teach you about ecosystem balance? Which change caused the biggest effect, and why?
Formative assessment through observation, team explanation, and prototype performance. Use a simple rubric or checklist for: ecosystem accuracy, use of sensor/program response, teamwork, and explanation of how the model represents ecosystem interactions.
Write a short paragraph or draw a labeled diagram of a real ecosystem, explaining one change that could affect balance and how living things might respond.
