Title
Fruit Explosion

Broad Question
What type of fruit will hold the most pressure?

Specific Question
Out of three different fruits (apple, orange cantaloupe) which will hold the most psi?

Hypothesis
It is hypothesized that Cantaloupe will hold the most pressure followed by orange then apple.

Independent Variable:
Fruit Types

Dependent Variable:
Air Pressure

General Plan
This experiment was conducted to see what amount of internal pressure fruits could withstand until they exploded. First a table was set outside close by a compressor. Next five of each fruits were set down on the table. A needle was attached to the end of the compressor hose. The needle was slipped inside one fruit and tested at a steady pressure that was slowly increased for 30 seconds until the fruit could hold no more. They were tested in the order of Cantaloupe, orange, and then apple. One at a time they were tested until all data was recorded down in a notebook.

Experimental Design
(add the correct headings from the experimental design page before beginning)

Time Line
**Wednesday February 29- Design Home ** **Saturday March 3- Materials collected ** **Monday March 5- First trials of experiment data collection ** **Monday March 12- Experiment Trials data collection **

Detailed Procedure
1. Put the table next to the shed outside near the compressor. 2. Spread apart fruits so they do not damage other fruits when they explode. 3. Attach the needle to the compressor hose. 4. Put the needle in the first fruit. (Apples needle goes in 3 in. hold needle inside fruit ) 5. Test the Psi’s that they can withstand 6.Record Data 7. Put the needle in the next fruit (oranges needle goes in 3in) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">8.Test the Psi’s that this fruit can withstand. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">9.Record Data <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">10. Put the needle in the next fruit. (Cantaloupe needle goes in all the way) <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">11. Test the Psi’s that this fruit can withstand <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">12.Record data <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">13. Repeat steps 4-12, 4 more times. <span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">14. Take all recorded data and make an average for each fruit.

Results
<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">Results: An experiment was conducted to find out whether a cantaloupe, orange, or apple could hold the most air pressure. The apple held 12.5 psi before it exploded. Orange held 24 psi before it exploded. The cantaloupe held 90 psi before it exploded.

<span style="background-color: transparent; color: #000000; font-family: Arial; font-size: 15px; text-decoration: none; vertical-align: baseline;">This experiment concluded that cantaloupe could hold the most pressure per square inch with 90 psi. Followed by orange with 24 psi and then apple with 12.5 psi.
