This challenging worksheet stretches first graders with stage-specific science questions. Part A's four multiple-choice items ask which animal goes through a chrysalis (butterfly), why a tadpole must live in water (it breathes through gills), which stage comes right after a chicken hatches (chick), and what every life cycle has in common (they repeat).

Part B adds five fill-in-the-blanks on a butterfly using its tongue to drink nectar, frog eggs laid in a group called spawn, a hen keeping a chick warm before hatching, caterpillars shedding skin as they grow, and the cycle starting again when adults lay eggs. The activities push beyond stage names into behavior and anatomy.
