Here are the questions you should be able to answer after completing this scientific project:
1. What cube of ice melts?
2. How the effect of the colors of ice cubes melt?
3. What is done, you tell the heat absorption of the colors?
4. Do dark colors absorb more heat than light colors?
Now we have to start the experiment:
You know what's the first thing you do? Yes, you formulate your hypothesis! By doing this experiment to see what ice, covered with different colors, background, what do you think your hypothesis should be? It is good to know: dark colors absorb more heat than light colors.
What you need for this project easy science fair (called hardware):
• Several different colors of fabric about 6 or 7 inches square, much as he can, but at least 5 different colors
• A pair of scissors
• A bucket of ice for each color of the fabric, the ice cubes should be more or less the same size
• A good food scale that can weigh very small differences
• A large baking sheet or tray
• A pen
• A notebook
• Camera
How this experiment (called the procedure):
1. Cut pieces of fabric to a size slightly larger than the top of the ice
2. Now that you have to weigh each ice cube and record the weight
3. Place ice cubes on cookie sheet
4. Take a picture of the screen
5. Top each ice cube with a piece of cloth
6. Be sure to note the color that is placed on the ice cube and you must calculate the percentage by weight of each cube missed the final minutes.
7. Again, take a picture of the screen
8. Cookie sheet Place in the Sun
9. Leave on for 15 minutes, if not too hot. If it is too hot and cubes will melt very quickly, you have to see how they were before. It must be working for you
10. Take a picture of the screen
11. Take the rocks again and take a picture of the screen
12. Weigh each bucket of ice as quickly as possible to prevent the merger
13. Enter the weight of each
14. Now that you have to determine the percentage of weight lost each cube. Here's how: take the weight of the ice cube and subtracting the final weight of the ice cube it. This amount is divided by the initial weight multiplied by a hundred to get the percentage. A formula to show you it will be easier:
(Initial weight) - (final weight) / initial weight x 100 percent = cast
Can you think of what you can do on your screen now? Yes, you have to do a graph to show the differences in the percentage of each ice cube melted.
Now you can go to its conclusion on the difference of different colors absorb heat.
