Test early learners' ability to evaluate three simple pond-protection plans—planting trees around the pond, creating a rain garden to reduce runoff, or organizing regular trash cleanups—by assessing their understanding of how each action affects water quality, animal habitat, and long-term protection; require selecting the best plan for protecting a small pond and its animals and giving an age-appropriate justification that compares benefits, trade-offs, and maintenance needs (responses may be oral, written, or drawn; include rubrics for causal explanation and clear reasoning).
