Free and Easy Science Experiment Steps
Procedures
Get an apple
Cut the apple in nine slices
Sprinkle the first bag with salt
Sprinkle the second bag with sugar
Keep the third bag the same
Place three apple slices in each bag
Wait for one week and record results
Hypothesis
If apple slices are placed in re-sealable bags, then the ones that have not been sprinkled with salt or sugar will rot fastest, because sugar and salt help preserve the apple slices better.
Data and Observations
Date Control Sugar Salt 11/17/12 Placed in bag Placed in bag Placed in bag
11/18/12 Nothing Sugar melted Salt partially melted
11/19/12 Starting to oxidize Nothing Nothing
11/20/12 Continues to oxodize Nothing Salt finished melted
11/21/12 Continues to oxodize Slices shrunk Slices look preserved
11/22/12 Starts to rot Shrunk more Became soft
11/23/12 Rots Slices become squishy Absorbed salt
11/24/12 Slices are rotted Slices are bendable Slices are squishy

Abstract
I was trying to see which apple slices will rot the fastest. The slices without any preservatives rotted and the other slices with preservatives didn’t rot. What I found out that was significant was that my hypothesis was correct.
Statement of Purpose
In my investigation I was trying to figure out which apple slices will rot the fastest.
Conclusion
The hypothesis was correct the apple slices that were not

Bibliography: Analysis and Discussion The hypothesis was correct according to the experiment the salt and sugar did preserve the slices. In other experiments the apple slices that were sprinkled were preserved also.
