  1. 1. Science Inquiry Project Teri Cozart Sara Elmore Organic and Non-Organic foods and mold growth
  2. 2. The Question: Does organic food mold faster than non-organic food? Does organic apples, bread, bananas, baby food, or potatoes mold faster than non-organic bread, bananas, baby food and potatoes?
  3. 3. RECENTLY, WE HAVE BEEN TRYING TO EAT MORE ORGANIC FOODS DUE TO THE FACT WE SUPPORT LOCAL FOOD OWNERS. BUT AS WE WERE BUYING ORGANIC FOODS THAT WE NORMALLY BUY NON-ORGANIC, WE WERE WONDERING IF THE FOOD BEING “MORE HEALTHY” AND ORGANIC IF IT WOULD LAST LONGER AS WELL. Origin of the Question
  4. 4. Hypothesis Reason for Hypothesis  We predict that there will be no change in whether or not the food is organic or non- organic, the food will mold at the same rate or equally.  We predict this because even though the organic foods do not have all of the preservatives in it, it is still food and will more than likely spoil and grow mold at the same rate.
  5. 5. WE WILL BUY THREE OF EACH ORGANIC AND NON-ORGANIC FOODS (APPLES, BREAD, BANANAS, BABY FOOD, AND POTATOES). Procedures
  6. 6. WE WILL CUT EACH ORGANIC AND NON ORGANIC FOOD INTO SLICES AND PLACE THREE SLICES OF EACH IN PLASTIC BAGGIES. Procedures continued..
  7. 7. FOR THE BABY FOOD WE WILL PLACE TWO TABLESPOONS INTO A PLASTIC BAGGIE. Continued..
  8. 8. WE WILL LABEL EACH FOOD ORGANIC AND NON ORGANIC SO THAT WE WILL NOT GET THE TWO CONFUSED Continued..
  9. 9. WE WILL OBSERVE THE CHANGES IN THESE FOODS OVER A PERIOD OF THREE WEEKS AND RECORD DATA AT THE END OF EACH WEEK. 9/24 10/1 10/8 Continued…
  10. 10. THE FOOD (BREAD, BANANA, BABY FOOD, APPLE, POTATO) IS GOING TO BE THE INDEPENDENT VARIABLE. Independent Variable
  11. 11. WHETHER OR NOT MOLD GREW OR APPEARED ON THE FOOD SERVES AS THE DEPENDENT VARIABLE. Dependant Variable

  14. 14. Mold; what is it?  Molds are microscopic fungi that live on plant or animal matter. ("United states department," 2010)  Mold growth is encouraged by warm and humid conditions. ("Centers for disease," 2010)
  15. 15. Percentages Description  0-10% covered in mold  11-30% covered in mold  31-50% covered in mold  51-75% covered in mold  76-100% covered in mold  We would observe the food at the end of each week and ranked the amount of mold growth on the food by the scale given. How did we measure the mold?
  16. 16. Data over 3 week Period THE TABLE USED WILL SHOW EACH FOOD BOTH ORGANIC AND NON ORGANIC AND WE WILL WRITE YES OR NO DEPENDING ON WHETHER MOLD IS PRESENT ON THE FOOD EACH WEEK WE WILL RECORD DATA IN THIS WAY.
  17. 17. Apple Organic Mold Growth Non-organic Mold Growth Week 1 NO 0-10% of mold growth NO 0-10% of mold growth Week 2 NO 0-10% of mold growth NO 0-10% of mold growth Week 3 NO 0-10% of mold growth NO 0-10% of mold growth Final

  22. 22. Organic Food Non- Organic Food Apple Banana Bread Baby Food Potato Apple Banana Bread Baby Food Potato Mold on Foods
  23. 23. Overall Mold on Food • At the end of three weeks we found that the Non-Organic food did develop more mold overall, just depending on the food. Organic Food Non-Organic Food Non-organic: 54% mold growth overall Organic: 46 % mold growth overall
  24. 24. Results •From our experiment we found that there was not much of a difference between the mold growth on organic and non-organic foods. •On some foods mold grew more and at a faster rate on organic foods, and some on non-organic foods. •The baby food and bread were the foods that had different data at the end of three weeks. Non-organic baby food grew more mold, but the organic bread grew more mold than the non-organic bread.
  25. 25. Conclusion Our original question was, does organic food mold faster than non-organic food? From our experiment there is no inclination that non- organic food or organic food grows mold faster than the other.
  26. 26. Continued.. We came to the conclusion that mold growth does not depend on whether or not it is non-organic or organic, but the type of food it is and how much moisture is in the environment of the food
  27. 27. •WE WONDERED IF THE AMOUNT OF MOLD GROWTH WOULD HAVE BEEN AFFECTED IF WE LEFT THE FOOD OUT IN THE OPEN RATHER THAN SEALED IN A BAG? • I WOULD LIKE TO TRY DIFFERENT FOODS, TO SEE IF I GET THE SAME RESULTS AS WE DID IN THIS EXPERIMENT. • I QUESTION THE LEVEL OF ORGANIC FOOD THAT WE BOUGHT, IF THE FOOD WOULD HAVE BEEN 100% ORGANIC WOULD WE HAVE DIFFERENT RESULTS? Next Steps and/or Questions
  28. 28. Claims Evidence  Being organic or non- organic does not have much of an influence on mold growth, instead it is the type of food , and its environment.  The potato had more mold than any other food, both non-organic and organic.  31-50% of mold growth on both the non- organic and the organic potato! Claims & Evidence
  29. 29. Claims Evidence  Moisture affects the growth of mold on foods.  The foods that produced the most moisture in the baggies, grew more mold.  The non-organic baby food, and both of the potatoes were the baggies with the most moisture and both had 31-50% of mold growth developed. Claims & Evidence
  30. 30. •THROUGH OUR EXPERIMENT, WE DID NOT FIND A DIFFERENCE IN THE AMOUNT OF MOLD GROWTH IN ORGANIC AND NON-ORGANIC FOODS. •IN OUR RESEARCH WE FOUND THAT NON -ORGANIC FOODS SHOULD ACTUALLY STAY FRESHER BECAUSE OF THE PRESERVATIVES ADDED. Reflections
  31. 31. •THERE ARE MANY OTHER FACTORS THAT DEPEND ON HOW HEALTHY THE FOOD IS. (COMPOSITION OF THE SOIL, THE GENETIC MAKEUP OF THE PLANT, THE DEGREE OF MATURITY AT HARVEST & METHODS OF HANDLING AFTER HARVEST.) •THE RESULTS OF THIS EXPERIMENT COULD VARY IN RESULTS IF REPEATED DEPENDING ON WEATHER, SEASON OR OVERALL ENVIRONMENT. Reflections
  32. 32. THIS EXPERIMENT DID NOT ANSWER OUR ORIGINAL QUESTION, BUT DID COINCIDE WITH OUR HYPOTHESIS THAT THERE WOULD BE LITTLE OR NO DIFFERENCE IN THE MOLD GROWTH ON THE TWO TYPES OF FOODS. Reflections
