 * __Ice melt__**

Broad Question
what is the affect of method on melting rate

Specific Question
does method used affect melting rate

Hypothesis
it is hypothesized that salt will be the fastest and leaving it out in the sun will be the slowest.

Independent Variable:
method used

Dependent Variable:
melting rate

Variables That Need To Be Controlled:
method used Vocabulary List That Needs Explanation

General Plan
I will get 4 identical plastic containers and 4 ice cubes. Each container will get one ice cube. Then one container will get salt water, one will be left out at room temp, another will be left outside, and the other will be sealed (air tight). Then i will time each of them at different times. After that i will record the data and other observations.

Detailed Procedure
1. Grab 4 of the same container 2. Put ice cubes of the same size in each 3. then put ice water in one 4. leave one outside in the sun 5. put on in room temp 6. and put one in an air tight container 7. then monitor how long it takes for the ice to melt 8. record the time Diagram

Conclusion
My question was does method used affect melting rate of ice. My data shows that it did. The time for sun was way longer than salt.

Discussion
I chose this experiment because it sounded fun. There was a strong relationship between my two variables. The melting rate depended on the method of melting. I was able to answer my experiment when i completed my first two trials, when the melt times were different. I do not really think my experiment will be of use to anyone. I had no errors in my experiment. To improve my experiment I think I could add more methods and more trials.

Abstract
In my experiment I tested would the method used affect the melting rate of ice. It was hypothesized that leaving it out in the sun would take the longest and salt would be the quickest. My prociedure was I will get 4 identical plastic containers and 4 ice cubes. Each container will get one ice cube. Then one container will get salt water, one will be left out at room temp, another will be left outside, and the other will be sealed (air tight). Then I will time each of them at different times. After that I will record the data and other observations. My results proved my hypothesis right the sun did take the longest and salt the shortest. I chose this experiment because it sounded fun. There was a strong relationship between my two variables.
