Lesson overview
What students will learn
- Develop and use a model to show ordered life-cycle stages and the connection from a reproducing adult to offspring in a new generation.
- Compare different life cycles and explain the shared pattern of beginning life, growth and change, reproduction, and eventual death across generations.
Key science ideas
- Organisms begin life, grow, and change.
- Adults can reproduce, producing offspring that begin a new generation.
- Individual organisms eventually die, but the life-cycle pattern can continue through offspring.
