SIP Tentative Methodology (Part 2)

Materials needed:

• 3 plastic transparent cups
• 10 small paper plates
• 3 plastic spoons
• Marker
• Juice extractor
• Knife
• Stopwatch 
• Measuring Cylinder

Materials for liquids:

• 100 ml Tap Water + 1 teaspoon of salt
• 2 Lemons
• 3 Limes
• 1 peach (cut into 10 equal slices)

Method:

1. Label all plates and cups with a marker. Arrange everything on the table, such that there are 3 rows of 3 sets of plates

2. Squeeze the fruits using the juice extractor and pour the juice into the cups. Prepare the salt water.

3. Cut the peaches into 10 equal slices. Drop 3 slices into each liquid, making sure all 3 slices are fully submerged in the respective liquids. Place the final slice on the control plate.

4. Start the stopwatch immediately when all the peach slices are in the liquid. 
5. After 5 minutes is up, take one peach slice from each cup and place it on the first row of plates.   
6. Observe each peach slice for the first sign of browning and record the time this occurred.
7. At the same time, continue timing with the stopwatch. Repeat steps 5 and 6, but this time take the peaches out 10 and 15 minutes after the start of the experiment. Place the peaches on the second row and third row of plates respectively.
