Lesson plan for a 4th grade class on the life cycle of butterflies. The students will be divided into 4 groups of 5. They will play an online hangman game to review vocabulary. Then each group will research butterfly anatomy using provided websites, design their own butterfly by labeling its body parts, and write a brief description. Next, the groups will investigate the butterfly life cycle using additional websites and videos, and answer questions. Finally, students will present their butterfly drawings and descriptions on a classroom poster.
