Swamps: Exploring a Wetland Ecosystem
Suggested grades: 2–5, adaptable Time: 3–5 sessions Subjects: Science, Mathematics, Reading, Writing, Art
Overview: Students investigate swamps as wetland ecosystems, using observation, measurement, food webs, research, art, and communication. The original Everglades activities are retained where useful, but the lesson now emphasizes accurate ecological relationships rather than separate “intelligences.”
Learning Objectives
- Identify characteristics of a swamp or other wetland.
- Describe relationships among producers, consumers, and decomposers in a food web.
- Measure and record water volume using appropriate units.
- Use observations and reliable sources to describe plants and animals of a wetland.
- Communicate scientific information through writing, models, art, or oral presentation.
Materials
Age-appropriate wetland books and current park or wildlife resources; measuring containers; water; graph paper; plant/animal cards; art materials; optional live tadpole or butterfly observation only if permitted by school policy and appropriate care can be provided.
Procedure
- Activate knowledge: Show photographs of several wetlands. Ask students what they notice about water, soil, plants, and animals. Introduce wetland, habitat, producer, consumer, and food web.
- Read and research: Read The Steamy Swamp or another age-appropriate wetland text. Students record three facts and one question. Use specific sources when studying the Everglades; avoid treating all swamps as identical.
- Measure water: Students measure different quantities of water and record the results. Older students convert between units when appropriate and compare measurements.
- Build a food web: Use organism cards to construct several possible feeding relationships. Add arrows according to the class convention and explain that a food web contains multiple connected food chains.
- Plant study: Students research or examine photographs of several wetland plants. Create labeled cards or a field-guide page with the plant's name, habitat, and one identifying characteristic.
- Observation: If tadpoles or butterflies are observed, students record changes over time rather than simply “watching.” Use photographs or video if live organisms are impractical.
- Communication: Students create a swamp diorama, mural, ecology puzzle, poem, or short presentation that includes accurate scientific information. Older students can prepare a short presentation for younger students.
- Local connection: A ranger or state-park speaker may be invited. A virtual or recorded presentation can substitute.
Assessment
Students submit a labeled wetland model or field-guide page, interpret a simple water-measurement record, and explain at least one food-web relationship. Older students should distinguish an observation from information learned from a source.
Safety
Do not require students to enter wetlands. Follow school procedures for field trips, water, insects, plants, and wildlife. Handwashing is required after handling natural materials or organisms.
