Teacher manual for Advanced Environmental and Earth Sciences labs. Has both the printed version and a flash drive with teacher tips, a PDF of teacher version and editable Word student version.
Sunlight & Reflectivity
Use a light sensor, a fast-response temperature probe, and a stainless steel temperature probe to explore the concept that air temperatures near the earth's surface result largely from the interplay of the sun's incoming energy and the absorption, reflection, and radiation of that energy by materials on the earth's surface.
Students explore the concept that air temperatures near the earth's surface result largely from the interplay of the sun's incoming energy and the absorption, reflection, and radiation of that energy by materials on the earth's surface. In the process, students:
- Analyze the laboratory evidence showing the differences in reflectivity of various earth materials.
- Explain the effect of the earth's reflectivity on surface temperatures.
Students gain experience conducting the following procedures:
- Using light and temperature sensors to measure the reflectivity (albedo) of various earth materials.
- Using light and temperature sensors to measure air temperature and sunlight intensity throughout the day.
Sensors / Equipment Used:
MultiMeasure sensor that incorporates pH, conductivity, temperature, and the optical dissolved oxygen probe.
Features a wide measurable range by offering three light ranges accommodating various different measurement situations. For use with PASPORT Interfaces.
