You have 4 plastic cups filled with water. Each cup is a different color. What is the best way to investigate to see which color will increase the temperature of the water the most when placed outside?

• Place 2 of the cups on the sidewalk in direct sunlight and 2 of the cups in the shade in the grass. After 20 minutes measure the temperature of the water in each cup. Compare the temperatures of the cups in the sun to the temperature of the cups in the shade.

• Place all 4 cups on the same surface in direct sunlight. After 20 minutes measure the temperature of the water in each cup. Compare the temperatures to see which is the highest.
