Ecosystem problem solving
Students will apply their knowledge of ecosystems and the interdependence of plants and animals to creatively solve problems.
A lesson plan for grade 5 Science
Learning outcomes
Students will:
- Gain a better of understanding of how parts of an ecosystem work together as well as gain an appreciation of the importance of balance in the ecosystem.
- Practice their problem solving and critical thinking skills.
- Get a clearer idea of the kinds of problems “real” scientists solve.

Fuzzy Situation cards
Pre-activities
Students should have a clear understanding of an ecosystem (‘eco’ = home, habitat; ‘system’ = parts working together). They should be able to identify the living and nonliving factors in the ecosystem and label a food chain according to producers, consumers (primary, secondary, tertiary, etc.), and decomposers. The students should fully understand the importance of balance in an ecosystem.
Activities
- Divide the class into five groups.
- Give each group a “Fuzzy Situation” (see attachments). Tell the students that they should be creative but reasonable when solving their fuzzy situations. For example, if they want to create a plant that does not need the sun for energy, that’s fine. But they must tell what the plant will use for energy instead.
- Have the students discuss their situations and come up with solutions to the problems. The teacher may provide assistance to stimulate thinking, but remember, these problems are supposed to be difficult! Emphasize the importance of using their problem solving skills to think through the problems.
- Have each group make a presentation to the class. In the presentation, they should read their fuzzy situation to the class, answer the questions in the fuzzy, and talk about how they solved the main problem in their situation. They should make a drawing of their ecosystem or a diagram of their food chain to include in their presentation. These presentations should not be elaborate but should instead give the rest of the class an idea of the variety of problems other students had.
Assessment
Teachers may evaluate the presentations for content (scientific knowledge) and quality (grammar, projection, etc.). Also, if teachers choose, they may include a group evaluation form where each student may evaluate his/her peers in the group.

Grade 5
- Goal 1: The learner will conduct investigations to build an understanding of the interdependence of plants and animals.
- Objective 1.01: Describe and compare several common ecosystems (communities of organisms and their interaction with the environment).
- Objective 1.02: Identify and analyze the functions of organisms within the population of the ecosystem:
- Producers.
- Consumers.
- Decomposers.
- Objective 1.03: Explain why an ecosystem can support a variety of organisms.
- Objective 1.04: Discuss and determine the role of light, temperature, and soil composition in an ecosystem's capacity to support life.
- Objective 1.05: Determine the interaction of organisms within an ecosystem.
