SCIENCE FAIR PROJECT Bacteria & bananas Audrey Alvarado| Mrs. McNees | Syracuse Jr. High School STATEMENT OF THE PROBLEM • In what conditions will a banana stay ripe? RESEARCH • facts: – “The specific nutrition contained in peel depends on the stage of maturity”, and that’s why I got all the same color. – “Many of these bacteria feed on dead organisms or organic waste”. – “As bananas, are a popular fruit consumed worldwide, with yearly production over 145 million tonnes in 2011, there is a significant amount of banana peel waste being generated as well”, the peel a are always being wasted so there plenty for bacteria. – Bacteria can cause food poisoning and bacteria can always be on your food. – They can live in extreme environments. • Citations – http://en.wikipedia.org/wiki/Banana_peel – Many authors, intergtated I science, 2011, page 747 HYPOTHESIS • If you put a banana in a green bag, it will then stay ripe, because it bacteria can’t eat the nurturance and its suppose to keep fruits fresh. PROCEDURE: MATERIALS • 4 bananas • Green bag • Brown bag • Refrigerator • Notebook • Sharpie, pen, pencil • Sticky notes PROCEDURE: STEPS 1. Place one banana on the counter, another in a brown bag, one in a green bag, and the last in the refrigerator. 2. With sticky notes Label each banana ( A, B, C &D) 3. Record the observations of each banana in the notebook for 7 day and state which is the best for each day. VARIABLES • Constants: from the same store, same color • Controlled variable: the green bag compared to the three others • Independent (manipulated) variable: the other conditions of the bananas. • Dependent (measured) variable: the amount of brown stuff DATA/OBSERVATIONS • Day 1: They all looked the same. • Day 2: The best is banana A • Day 3: The Best is banana A • Day 4: The new best is banana C • Day 5: still banana C • Day 6: still banana C DATA/OBSERVATIONS Day 7: This is the last day and the best by far is banana C. CONCLUSION • In conclusion in what conditions will a banana stay the most ripe? The answer is in a green bag, banana C was the banana in this bag. The reason I think that this was that answer was because I only opened the bad once to take a photo and so the air couldn’t get in and ether did the bacteria. Also the package for the bags says,” helps keep a variety of fruits & veggies fresh!”, so that’s what its suppose to do.
