Activity: Absorbing Sunlight in Different Colored Soil Surfaces
This lesson plan/experiment provides steps for testing the temperature of three different colors of soil placed in the same location. Students are then able to see how uneven heating of the earth can create wind. This resource shows heat absorption by varying surface materials affects land and sea breezes.
Alignment of this item to academic standards is based on recommendations from content creators, resource curators, and visitors to this website. It is the responsibility of each educator to verify that the materials are appropriate for your content area, aligned to current academic standards, and will be beneficial to your specific students.
Student will conduct an activity to identify the effects of solar energy on our planet and its systems by observing how 3 colored soils absorb sunlight differently.
Older students can learn about the albedo of a surface,a measure of the percentage of radiation striking the surface that is reflected back into space.
