This lesson plan teaches 2nd grade students about the phases of the moon through inquiry-based activities over the course of a month. Students will read a poem about the moon, create a KWL chart, make nightly observations of the moon in journals, and discuss their findings. They will learn the vocabulary for moon phases by comparing their observations to diagrams. The teacher will evaluate students' understanding through discussions, journal entries, and completing the KWL chart. The lesson incorporates universal design principles to engage diverse learners.
