Combine math and science with fun in the sun! Scientists build a solar gnomon using reusable materials to calculate relative air mass. Mathematicians measure the pole's shadow and use the data to solve for relative air mass. Investigators then complete discussion questions to analyze the effect of different variables on their results.

Concepts

air mass, atmospheric conditions, the atmosphere, solar radiation

Instructional Ideas

• Organize learners into teams of three for a collaborative experience
• For younger audiences, review differences in daylight by geographical location and seasonal change prior to beginning

Classroom Considerations

• Requires one dowel and meter stick for each group
• Activity needs sunlight, so check the weather forecast before beginning

Pros

• Hands-on learning experience allows participants to visualize abstract concepts
• Interdisciplinary activity combines math skills with science content

Cons

• None
