Albedo Effect and Climate Change
Objective: Investigate how surface color affects heat absorption and Earth’s energy balance.
Materials:
-
2 identical thermometers
-
White paper
-
Black paper
-
2 clear jars or boxes
-
Sunny outdoor space
-
Timer
Procedure:
-
Wrap one thermometer in black paper, the other in white.
-
Place each under a clear jar and set in direct sunlight.
-
Measure temperature every 5 minutes for 30 minutes.
Outcome:
The black paper absorbs more heat, showing how darker surfaces contribute to warming — a model for the melting of ice caps and climate change.
