1Big Idea 16: Heredity & Reproduction Life Cycles of Insects:Complete & Incomplete MetamorphosisMary TweedyCurriculum Support SpecialistDr. Millard LightburnScience Supervisor
2BenchmarksSC.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)
3Characteristics 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.
4Insects 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
