Variables That Need To Be Controlled:
The same amount of liquid, The same time drying, The same unit of measuring, Same temperature in room, Same time in the liquids

Hypothesis:
I hypothesize hydrogen peroxide will have the biggest effect followed by rubbing alcohol and lastly water.

Experimental Design
====I will conduct my experiment at my house because that is where I can have my experiment going for as long as I need. I will be the only person in my experiment. I will be conducting my experiment, recording data, and taking pictures. I am doing nine trials of each fruit and three of each liquid for each fruit, making a total of twenty seven trials. I will be printing out the spreed sheet to record data. I will be taking pictures of the cups, every five days. Then I will download the pictures to the computer. ====

Conclusion
<span style="background-color: #ffffff; color: #ff3800; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">The original purpose of this experiment was to see which liquid, out of water, rubbing alcohol, and hydrogen peroxide would have a greater effect on the structure of peach, banana, and orange skin.The results show that rubbing alcohol had the greatest effect on the fruit skins. Rubbing alcohol ranged from losing 1.9 oz. to 6.3oz for the fruit skin. Next was hydrogen peroxide which ranged from orange skin gaining .9 oz. to peach skin losing 2.5 oz. Last was water. Water ranged from banana skin gaining 1.9 oz. to peach skin losing 2.8 oz. The final average for peach skin was rubbing alcohol 5.7 oz., water 1.67 oz., and hydrogen peroxide 2.1 oz. Next banana peel had an average of rubbing alcohol 5.1 oz lost, water 1.2 oz. gained, and lastly hydrogen peroxide with a average weight loss of .5 oz. Finally, orange peels were rubbing alcohol lost 2.23 oz., water lost 1.47 oz., and hydrogen peroxide being the second peel to have an gained weight average was .47 oz.

Discussion
<span style="background-color: transparent; color: #ea17ed; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">My hypothesis was that hydrogen peroxide would have the greatest effect followed by rubbing alcohol, then lastly water. My results do not support my hypothesis. A trend shown throughout the experiment was that the rubbing alcohol was evaporating quickly. By day five the water was noticeably getting lower in the cup. At day fifteen it looked like there was half as much rubbing alcohol left in the containers than when the peels were first put in the container. Hydrogen peroxide also evaporated, but not as much as the rubbing alcohol. Water seemed to have not evaporated at all. The independent variable (liquids) and the dependent variable (fruit skins) does have a relation because rubbing alcohol had a drying effect on the fruit skins and water had the least drying effect. <span style="background-color: transparent; color: #ea17ed; font-family: Arial; font-size: 16px; text-decoration: none; vertical-align: baseline;">I think my test went very well. I had not problems throughout the experiment. Everything went as I had it written down in my procedure. If I could improve my experiment, I would like to use liquids that can have a more damaging effect to the fruit skins. I would also like to have more fruit skins in the experiment. An interesting future study would be to to use the actual fruits. In the past I have done the drying effect a dehydrator has on citrus and non-citrus fruit so now I could use liquids for that procedure because I have knowledge of the effect on the skins.
