Materials List: 1 Ice Tray or similar container for liquid About 2 cups of water 1 piece of black cloth about the size of notebook paper 1 piece of white cloth about the size of notebook paper 1 piece of green cloth about the size of notebook paper 1 piece of yellow cloth about the size of notebook paper A freezer or another way to freeze the water Access to the outdoors Scissors Timer Paper Pencil Plate

Procedure: 1. Pour the cups of water into the ice tray. 2. Put the ice tray into the freezer gently. 3. Wait for a few hours to let the water freeze completely. 4. Once the water has been frozen thoroughly, take the ice tray out of the freezer. 5. Remove 4 ice cubes from the ice tray and place them on a plate. 6. Put the ice tray and any remaining cubes back into the freezer. 7. Gather up your 4 different colored cloths. 8. Use the scissors to cut the cloths to be about the size of a small square big enough to cover the top of the ice cubes. 9. Once you have made the 4 different colored squares, place each colored cloth on a different ice cube out of the 4 you removed from the ice tray. 10. Retrieve your timer, paper, and pencil. 11. Go outside at noon with the plate of ice cubes and place it on the ground in a sunlit area. 12. Immediately start the timer and take note of at what time does each of the ice cubes melt completely on the paper you have with your pencil. 13. After each ice cube has melted completely and you have the data for each, stop the timer and retrieve all of your materials then head home.
