Mayfly Life Cycle
Mayflies are insects that have a unique lifecycle. The adult mayfly stage is focused on reproduction and the resulting swarms can often be seen around rivers in Iowa.
Driving Question
- Why does the mayfly only live for a few days?
Probing Questions
- What makes the mayfly unique?
- What do all life cycles have in common?
- Why do organisms reproduce?
Classroom Suggestions
Students could:
- Use one or more of the lessons from the Iowa Land and Sky: Iowa Plant and Animal Reproduction Storyline.
- Identify an organism and research their life cycle (birth, growth, reproduction, and death).
- Create a model to depict the life cycle of a given organism.
- Compare and contrast models of the life cycles of various organisms.
- Discuss how the patterns found in all life cycles can help make predictions (i.e. without births an organism could die out)
