Oh No, O3zone: “Good Up High, Bad Nearby!”

Oh No, O3zone: “Good Up High, Bad Nearby!”

This module teaches students about ozone’s role in the atmosphere and explores authentic data to compare and contrast conditions that affect ground-level ozone values.

Context for Use

The four DISCOVER-AQ modules can be completed independently, sequentially, or extended into a larger unit of study.

The “Know Your AQ” curriculum applies the 5E Instructional Model:

  • Engage (15 minutes) - Ozone Video & Image

Interest in ground-level ozone is generated and students’ current understanding of ozone’s roles in the atmosphere is addressed.

  • Explore (35 minutes) - Ozone Formation

Students participate in kinesthetic activities to explore the process ground-level ozone formation and factors that affect its levels in the atmosphere.

  • Explain (30 minutes) - O3nce Upon

Students construct their understanding of conditions that affect ground level ozone formation and transport and develop evidence-based explanations using research data.

  • Elaborate (15 minutes) - Ozone Alerts & AQI

Students deepen and expand their understanding of how individuals can access information on air quality conditions and actions that they can take to reduce air pollution.

  • Evaluate (5 minutes) - Ozone Quick Quiz

Students and teachers have opportunities to assess students’ basic understanding of ground-level ozone formation.
