1 Big Idea 16: Heredity & Reproduction Life Cycles of Insects:Complete & Incomplete MetamorphosisMary TweedyCurriculum Support SpecialistDr. Millard LightburnScience Supervisor
2 BenchmarksSC.4.L Compare and contrast the major stages in the life cycles of Florida plants and animals, such as those that undergo incomplete and complete metamorphosis, and flowering and nonflowering seed-bearing plants. (Cognitive Complexity Rating: Moderate) SC.5.N.2.1 Recognize and explain that science is grounded in empirical observations that are testable; explaining must always be linked with evidence. (Cognitive Complexity: Moderate)
3 Characteristics of Insects Insects are small animals with a head, athorax, an abdomen, and six legs.All insects start their lives as eggs.These eggs can be different colors, shapes, and sizes.All insects go through metamorphosis after birth.
4 Insects and Metamorphosis Life Cycles of InsectsAnimals that change their appearance during growth undergo metamorphosis. That's just a long word meaning "to change shape.“ The change that occurs when an insect egg hatches and grows into an adult is called metamorphosis, meaning to change in form.Insects and MetamorphosisCreate a foldable:Pasta Lifecycle:Use pasta to show thelifecycle of a butterfly. Use cavatelli forthe caterpillar, small circles for the eggs,shells for the chrysalis and bow ties forthe butterfly. Glue them onto a piece ofconstruction paper folded into 4 parts.Draw arrows to define the stages of thelifecycle. Have students label each phase
