Assess students' ability to design a small backyard habitat model (drawing or simple physical model) for Pre‑K to Grade 2 that supports at least three local animals, conserves water, and prevents pollution. With teacher guidance, learners will choose native plants and habitat features (shelter, food, water source), include at least one water‑saving element (e.g., rain barrel, drought‑tolerant plants, mulch), and one pollution‑prevention strategy (e.g., no‑chemical care, plant buffers, litter control). Deliverables: labeled drawing/model, short materials list, and an age‑appropriate explanation (spoken or illustrated) showing how each feature helps wildlife and protects water. Evaluation focuses on creativity, ecological accuracy, clear connections to water conservation and pollution prevention, and communication appropriate for early learners.
