Department of Mathematics and Science Big Idea 16: Heredity & Reproduction Life Cycles of Insects: Complete & Incomplete Metamorphosis Life Cycles of Plants: Flowering and Nonflowering

Department of Mathematics and Science Benchmarks SC.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.4.N.1.1 Raise questions about the natural world, investigate them in teams through free explorations, and generate appropriate explanations based on those explorations. Cognitive Complexity: High

Department of Mathematics and Science Characteristics of InsectsInsects Insects are small animals with a head, a thorax, 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.

Department of Mathematics and Science Life CyclesLife Cycles of Insects Animals 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.metamorphosis Insects and Metamorphosis
