🌦️ Weather Patterns Over Time
Grade 3 Earth Science — Quick Reference Card
Big Idea
Weather records help scientists notice short-term patterns across several days.
Key Vocabulary
- Weather: what the air and sky are doing right now
- Observation: a detail you notice and record
- Pattern: something that repeats in a useful way
- Precipitation: rain, snow, sleet, or hail
Remember This
- One day of weather is an observation. Several days can show a pattern.
- Use the weather record itself as evidence when you explain a pattern.
- A pattern can include changes that repeat, not only things that stay exactly the same.
