The Standard

common and extreme weather events affect ecosystems

Virginia Standards of Learning for Science

Teacher's field guide

What Students Need to Do: Students connect weather conditions such as rain, heat, wind, drought, and floods to changes in habitats and living things. They explain these changes with clear cause-and-effect chains.
What Mastery Looks Like: Students can predict how a weather event will affect plants, animals, soil, and water in an ecosystem. They support each prediction with evidence about organisms' needs and habitat conditions.
Common Misconceptions: Students may think extreme weather affects every organism in the same way or always causes permanent damage. They may also overlook how regular rain, wind, and temperature changes shape ecosystems over time.
How to Assess It: Exit ticket: A meadow receives regular spring rain, then a two-day flood. Name one ecosystem effect of each and explain the flood with a two-step cause-and-effect chain.

Lesson moves

Use trays of soil, grass, and water to model heavy rain, then record erosion, pooling, and plant damage.
Students explain how a week without rain could affect plants, rabbits, and hawks, using a three-step cause-and-effect chain.
Play weather-impact match by pairing event cards such as frost or flood with ecosystem effect cards, then defending each match.
Check a local weather report, then predict one effect on a nearby stream, park, garden, or animal population.
