Lesson 4: Analyzing Sunlight Data

Key Idea.

Section 1

Quantifying Light Energy

Key Idea

Scientists collect quantitative data to measure exactly how much energy arrives at different locations on Earth.

By comparing "Solar Intensity" data, we can confirm that Australia receives a significantly higher amount of energy per square meter than many other places. This intense energy input is a primary suspect in the health investigation.

Section 2

Cumulative Energy and Correlation

Key Idea

Damage to materials is often a result of cumulative energy—the total amount of energy absorbed over a long period.

Even if sunlight is not immediately burning, small amounts of energy absorbed every day add up over years to cause significant damage.
