Benchmarks
Big Idea 16: Heredity and Reproduction• SC.2.L.16.1 Observe and describe major stages in the life cycles
of plants and animals, including beans and butterflies. Cognitive Complexity: Moderate
• Big Idea 1:The Practice of Science• SC.2.N.1.2 Compare the observations made by different groups
using the same tools. Cognitive Complexity: Moderate
• SC.2.N.1.5 Distinguish between empirical observation (what you see, hear, feel, smell, or taste) and ideas or inferences (what you think). Cognitive Complexity: Moderate

Lesson Objectives:By the end of this lesson, students should be able to:• Observe and identify major parts of a seed.• Observe the germination and growth of a bean seed.• Observe and measure the bean plant seedling as it grows and changes
into an adult plant in terms of stem growth and number of leaves.• Explain the major stages of a flowering plant and how it grows and
reproduces.• Identifies and explains the life cycle of a butterfly, frog, and mealworm.• Identifies and explains the life cycle of a bean and peanut.• Explain the major stages in an animal’s life, how it grows, and reproduces.
• Key Vocabulary:life cycle, stages, egg, larva, caterpillar, pupa, adult, young, froglet,germination, temperature, seed, seed coat, food storage, embryo, seedling,flower, fruit

What is a life cycle?
Every living thing grows through its own life cycle. They give birth to offspring like themselves, who grow, mature, reproduce, and then finally die.
Let’s learn more about the life cycles of living things.

Life Cycles Hunt: Evidence of Life Cycles around You
Let’s look at a organisms are at different stages in their life cycle. By observing their current stage, predictions can be made about their next stage of development.

Life 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.

Insect Life Cycle
Most insects go through metamorphosis, or changing form, in four stages of development. During the larva stages, insects eat almost constantly. Adult insects lay eggs hidden in various places for protection.
