Curated OER
How Hot is that Planet?
In this planet learning exercise, students read about finding the temperature of a planet using the distance to its star, its reflectivity and the luminosity of the star. Students use a given equation to determine the...

Identifying Materials by their Reflectivity
In this reflectivity worksheet, students read about the absorption and reflectivity of light by different materials. Students solve 4 problems and determine the composition of given materials based on the amount of light reflected. They...

Reflecting on Reflectivity
Students plan and construct a "mini-lab" to measure the reflectivity of different earth surfaces. They measure reflectivity of materials, including ice, soil, rocks, etc., and then extrapolate from what they have learned to consider the...
