2nd Grade Science Unit 10

Big Idea:

Investigate the life cycle of a butterfly.

Student Expectations:

Priority TEKS

2.10(C) [Supporting] investigate and record some of the unique stages that insects such as grasshoppers and butterflies undergo during their life cycle.

Focus TEKS

2.2(A) [Tools to Know] Ask questions about organisms, objects, and events during observations and investigations

2.4(B) [Tools to Know] Measure and compare organisms and objects using non-standard units that approximate metric units

Ongoing TEKS

2.2(A) [Tools to Know] Ask questions about organisms, objects, and events during observations and investigations

2.4(B) Tools to Know] Measure and compare organisms and objects using non-standard units that approximate metric units

2.2(D) [Ways to Show] Record and organize data using pictures, numbers, and words;

2.2(B) [Tools to Know] plan and conduct descriptive investigations

2.2(E) [Ways to Show] communicate observations and justify explanations using student-generated data from simple descriptive investigations; and

2.2(F) [Ways to Show] compare results of investigations with what students and scientists know about the world.

Student Learning Targets:

• I will identify the stages of a butterfly life cycle.
• I will compare the stages of a butterfly life cycle.
• I will explain how the body parts of a butterfly change during its life cycle to help meet its needs.

Essential Questions:

• How does a butterfly’s body change from one stage to another during a life cycle?
• How do the changing body parts of a butterfly help meet its needs?
