QuestionDoes salt water or lemon juice have any affect on the rate of dehydration of different types of apple slices?

HypothesisI predict that the salt water would have the effect on the rate of the dehydration because the water content of apples are retained with the presence of salty water.

MaterialsSalt waterLemon juice6 cupsA knife1 red apple, 1 green apple, and 1 golden appleSome waterA scaleA clock/timer

VariablesINDEPENDENT The shape of the applesDEPENDENTThe dehydration of the applesCONTROLLEDThe cups, the knife, and the scale

ProceduresGather all materials.Cut the red, green, and golden apples into 4 equal slices.Weigh the red, green, and golden apple slices separately.Pour water into a cup, then add a cup of salt.Split the different apple slices in half,dip1 half into the salt water and the other into the lemon juice.Let it rest for 5 minutes.Then, weigh the apple slices again, and record the data.Repeat steps 5,6, and 7 (2x) but dont repeat the part split the different apple slices in half.

Results(continued)Salt WaterLemon JuiceDiscussion of ResultsI inserted two slices of each type of apple into salt water. When I weighed the apples, the red apple had the most weight, with an average of 0.5167 kg. In second place was the golden apple with an average of 0.473 kg. Last was the green apple, with an average of 0.123 kg. Next, I took the other two slices of each apple and inserted them into the lemon juice. This time, the apple with the most weight was the red and green apple with an average of 0.473 kg. Last, was the green apple with an average of 0.153 kg.

ConclusionDuring the experiment, Ive realized that the salt water did effect the dehydration of the apples. The data shows that the weight of the apples dipped into salt water increased more then the weight of the apples dipped into lemon juice. Therefore, my prediction was correct.

Question?Now I wonder if I used different apples will my conclusion be the same.BibliographyI did not read any books.I did use the internet though, which was google, yahoo, and ask.com.I did not read an encyclopedia either.
