Life Cycles of Organisms
Develop models to describe that organisms have unique and diverse life cycles but all share the common stages of birth, growth, reproduction, and death
Suggested ages 7–9
Learning journey
Your child is diving deeper into how living things work — understanding plant life cycles from flower to seed, discovering how plants transport water, and learning about the important roles of skeletons, muscles, and proper nutrition.
Evidence of understanding
- Describe the life cycle of at least two different organisms (e.g. butterfly, frog, plant)
- Identify the common stages all life cycles share: birth, growth, reproduction, death
- Explain how life cycles can look very different (metamorphosis vs gradual growth) but follow the same pattern
Assessment prompt
Can Life Cycles of Organisms compare the life cycle of a butterfly with that of a frog and explain what stages they all share — being born, growing, having babies, and dying?
