Phenology in plants (flowering)

Laboratory Activity

A classroom/laboratory activity to learn about phenology and phenological events, and to understand the potential impacts of climate change on periodic life-cycle events in plants, specifically, on the bloom date of North American lilac shrubs.

Students will use phenology data on flowering patterns to create graphs, and will then interpret and discuss their findings.

Use this tool to help your students find answers to:

  1. Name some phenological events in plants and animals.
  2. What are the possible impacts of climate change on the flowering of plants?
