Can a color help you melt ice?
This experiment is conducted outside, through a sunny window, or using an overhead light.

Conducting the ExperimentWork with your teacher and group members to understand all the tools you will be using and how to conduct the experiment safely.
1. To prepare for the experiment, place exactly the same amount of water in each paper cup and place in the freezer overnight, or until frozen solid.
2. Design a cover for three of the frozen cups of water using construction paper or other material of your choice. One cover is black. Choose two other colors. (The material for the covers must be the same. The design of the cover must be exactly the same.)
3. List the colors on your journal chart.

Conducting the Experiment4. Choose a sunny location to conduct the experiment.
5. Place one of the frozen cups upright on a flat surface. Label this cup A. This is the control. It will not have a cover.
6. Place the other frozen cups upright on a flat surface. Completely cover them with the different covers. Label these B, C, and D. (Use a black cover on Cup D.)
7. Keep the graduated cylinders nearby for measuring melted water.

Conducting the Experiment8. Allow the cups to sit in the sun for five minutes. After five minutes, remove the covers.
9. Pour melted water from each cup into its own cylinder.
10. Record the amounts in your journal chart.
11. Replace the covers and repeat steps 8 – 10 two more times.

In Your Notebook
Discuss the activity and data with your partner. Record your ideas in your journal.
1. Compare the total amounts of water collected from each cup. 2. What difference did you notice? 3. Which cup of ice melted more quickly? Explain your answer.4. What effect do you think the colored covers had on the amount of melting in Cups B, C, and D?5. Draw a diagram of the direction of the flow of heat energy in your experiment. (Remember heat transfers to cold.)6. Using data from your table, create a line graph with time plotted on the x axis and water volume plotted on the y axis.
Solar cooking connection: The color black absorbs light and converts it to heat. Solar ovens use black to transform light to heat for cooking!
