Albedo is the term used to describe surface reflectivity. This activity looks at how decreasing sea ice in the Arctic Ocean contributes to a lowering of the albedo and an increase in the amount of solar energy absorbed in the region.
The name comes from the Latin albedo, which means ‘whiteness’. The albedo effect refers to the fact that light surfaces reflect more heat than dark ones. So, the lighter a surface, the greater its albedo, meaning it reflects more heat and light, and absorbs less. In this activity, we are going to use thermometers to test whether white or reflective materials absorbs more or less heat than black or dark ones.
