This article gives suggestions for building a simple walk-in classroom butterfly observatory and using the observatory to hatch out Painted Lady butterflies as part of a four-week unit on life cycle stages.
3-LS1-1 Develop models to describe that organisms have unique and diverse life cycles but all have in common birth, growth, reproduction, and death. Clarification Statement: Changes organisms go through during their life form a pattern. Assessment Boundary: Assessment of plant life cycles is limited to those of flowering plants. Assessment does not include details of human reproduction.

Comments about Including the Performance Expectation The Performance Expectation requires that students develop multiple models of a life cycle in order to study diversity in the life cycle. This unit would be an excellent way to introduce the concept at the start the year, and then the teacher could follow-up the project with another life cycle project with a different animal, such as ladybugs or brine shrimp.

Comments about Including the Science and Engineering Practice By watching the native butterflies that the students find in the garden form a chrysalis when they are first captured, it will give the students a reference point to make a prediction when the Painted Lady butterflies reproduce. For schools that do not have access to a schoolyard or garden to observe native butterflies, check with your local science center or botanical garden to see how local butterfly species might be obtained for observation.
This resource was not designed to build towards this disciplinary core idea, but can be used to build towards it using the suggestions provided below.
Comments about Including the Disciplinary Core Idea This unit only addresses butterflies, so an additional plant activity would need to be added to address that portion of the Disciplinary Core Idea. While students are not exploring other animals with this particular activity, the teacher might lead a discussion comparing and contrasting the butterfly's life cycle with other animal’s life cycles, as well as plant life cycles. This would help to address the complete standard.
This resource is explicitly designed to build towards this crosscutting concept.
Comments about Including the Crosscutting Concept By watching the native butterflies make a chrysalis and become a butterfly, the student will have background knowledge of a pattern in the life cycle process prior to raising the Painted Lady butterflies.
