Transcript of Organic vs Non Organic

Organic vs Non Organic Purpose The purpose of my project is to determine what lasts longer, organic or non organic fruits. Hypothesis If I have organic and non organic fruit of the same type, then the non organic will stay fresh longer. Source 1- "Chemical Sprays to Protect Fruit Trees" The Gardening Bible. May 14, 2011. http://www.thegardeningbible.com/chemical-sprays-to-protect-fruit-trees Basic sprays that are used are fungicides and insecticides. There are two types of sprays, contact and systemic. These sprays are used on fruits to kill pests and diseases. Source 2- "Organic Food" Wikipedia. http://en.wikipedia.org/wiki/Organic_food#References Organic foods are foods that are produced using methods that do not involve modern synthetic input such as pesticides and chemical fertilizers. Source 3- "Does Organic Food Last Longer" Love-Organic-Food.com. http://www.love-organic-food.com/does-organic-food-last-longer.html Organic foods do not contain preservatives. This might lead you to think they might spoil faster, but some preservatives might break food down faster if they are exposed to heat or extreme temperatures. Experimental Design The fruit will be our constants. The cold refrigerator and the room temperature counter top are the independent variables. The dependent variable is how the fruit will react. Materials 4 bowls
2 organic pears
2 non organic pears
20 organic raspberries
20 non organic raspberries
2 organic apples
2 non organic apples
Counter top
Camera Procedure I will put one organic pear, one organic apple, ten organic raspberries, one non organic pear, one non organic apple, and ten non organic raspberries on the counter at room temperature. I will put one organic pear, one organic apple, ten organic raspberries, one non organic pear, one non organic apple, and ten non organic raspberries in the refrigerator at 34 degrees. I will check them daily for browning. Organic vs. Non organic:
Type of Fruit vs. State of Fruit After 10 Days (0=fresh & 10=rotted) Results The temperature of the fruit affected the outcome. The organic fruit kept at room temperature spoiled faster than the non organic fruit, but the organic fruit kept in the refrigerator lasted longer than the non organic. Conclusion The results supported my hypothesis with the room temperature fruit, but not with the refrigerated fruit. the non organic fruit on the counter lasted longer because of the preservatives, but the refrigerated non organic fruit's preservatives reacted with the cold and spoiled faster.
