Introduction My problem is that I want to know how food coloring will affect how fast the ice will melt. I was interested because I love to play with food coloring. Also I love to chew ice. In addition I thought it would not be as hard to get my information or to find my materials.

Research! All research I have encountered indicates that the color of an object affects the amount of heat absorbed. According to exsperts123.com the darker the color of the ice increases the heat absorbed resulting in a faster melt time. That is because sun light is attracted to darker objects unlike lighter ice which will just reflect light. Water freezes as at an average temperature which is 0 degrees Celsius, and boils at an average 100 degrees Celsius. The melting point of water is the same as the freezing point which is 0 degrees Celsius but above it is the melting point and below it is the freezing point. If the ice is black, it will take in more heat and the ice cube will melt faster. If the ice is light colored or white, it won’t take in heat and the ice cube won’t melt as fast. That is because when sunlight is absorbed by the ice it will melt faster because the ice is hotter. Does the color of the liquid used to freeze ice affect the time it melts in? The short answer is yes because sunlight is attracted to darker colors because they will absorb more unlike the lighter colors that will just reflect the light. Also I did look at different temperatures at which different colors will freeze. Some of the colors I saw froze faster. This is because the different colors can keep in heat longer than others. Because the darker the color the faster the ice will melt. The lighter ice will take longer because it will reflect more light and not absorb as much light.

Experiment My question: does the color of the ice affect the time it melts in? My hypothesis: my hypothesis is that the darker ice will melt faster because it will absorb more light than the lighter ice will. My variables: Independent: the color of the ice. Dependent: the time in which the ice melts in. Control: the shape of the ice. Procedures: 1) take frozen or plain ice 2) put the other back in the fridge 3) start the stop watch 4) wait until melts 5) record data 6) repeat steps 1-5 until all information has been recorded Materials: 1) water 2) food coloring 3) freezer 4) stop watch 5) glass bowl

Conclusion All research I have done has lead to this conclusion: My hypothesis was true because the darker ice did melt faster. This was true because blue, green, and red. All melted faster than the lighter ones.
