Salt, Sand, And Measuring Teaspon
1. Prepare the salt, sugar, sand, and measuring teaspoon.
2. Once the ice cubes are set up in their bowls, quickly add the substances to the ice cubes so that they don’t melt before adding the substances.
3. Place three ice cubes quickly into each of the four bowls.
4. Arrange the ice cubes so that only the corners are touching, forming a triangular shape.
5. Carefully sprinkle ½ teaspoon (tsp.) of salt over the ice cubes in one bowl.
6. Sprinkle ½ tsp. of sugar over the ice cubes in another bowl
7. Sprinkle ½ tsp. of sand over the ice cubes in the third bowl.
8. Don’t sprinkle anything over the ice cubes in the fourth bowl.
9. Move each bowl to an empty shelf in the refrigerator. If any of the ice cubes do not form a triangular shape in their …show more content…
Record the starting time of the experiment. Try not to open the refrigerator for long periods of time for it may change the temperature of the refrigerator.
11. Check on the ice cubes every hour.
12. Once the ice cubes in one of the bowls have become at least half melted, take out all four bowls from the refrigerator. (Be sure to take the bowls out before the ice cubes in two or more bowls have completely melted.)
13. Pour the liquid water from one of the bowls into a measuring cup. Make sure the ice cubes stay in the bowl, but get as much water into the cup as possible. Then pour the liquid from the cup into the graduated cylinder. Record how much liquid was in the bowl (the amount of ice melted). After recording your results, clean and dry the cup and graduated cylinder.
14. Repeat step 13 with the three other bowls.
15. Now let the ice cubes completely melt in their bowls (you can leave them at room temperature). Once all of the ice cubes are melted, repeat steps 13-14 (but this time you will not need to worry about keeping the ice cubes in the bowls). Record the amount of liquid remaining in each bowl.
16. Calculate the total amount of water (originally in ice cube form) that was in each bowl (add the "amount melted" to the "amount remaining" for each
