This lesson plan outlines teaching students about the life cycle of a butterfly over 45-60 minutes. Students will learn vocabulary words related to the butterfly's stages, watch a video on the life cycle, color and assemble pages showing each stage, and take a quiz. Formative assessment includes observing students' work, and a summative quiz will test their understanding of the order of the life cycle stages. The lesson aims to meet a state standard for students investigating animal life cycles.
