2. Benchmarks SC.4.L.16.4 - 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, 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.
