Mrs. Garcia's earth science class conducted an experiment on how Earth absorbed solar radiation. They placed four different sheets of colored paper around the playground: white, tan, green, and black. After 15 minutes, several students were blindfolded and then asked to figure out the color of the papers by how cool or warm they felt to the touch. Predict which color the students said was the warmest and which one was the coolest to the touch. Explain why this happened.
