Irradiance

Light Source Efficiency: Exploring Irradiance

Grades:

6-8

Unit:

Lesson Number:

Description:

This lesson explores the concept of irradiance by having students use a Vernier Pryanometer. Using the “Light Source Efficiency” worksheet to guide their work, students measure irradiance as compared to the Sun’s irradiance to see what would be the best...

Energy Content:

Light (Visible),

Solar Photovoltaic

Learning Goal(s):

Using a Vernier Pyranometer, students will measure electromagnetic radiation in watts per square meter (W/m2 ). Students will compare Sunlight irradiance with various indoor lighting options. Students will make a recommendation as to the optimum indoor lighting for powering solar panels.
