"The chemicals strike back" Nathan Galvez Grade: 6 Science Can you tell the
organic and non-organic products
by taste? Question Overview I will be testing 10 subjects and 3 organic and non-organic products. Each subject will taste each product in its organic, and non-organic form.
I will record the data on a chart while the subjects taste the products. Purpose
The purpose of this
experiment is to analyze if organic products taste better than non-organic. I would want to find the answer because my mom buys organic products and my dad says there is no difference. This experiment can help people decide whether to buy by taste or for purely health reasons. Research Non-organic products contain tons of chemicals to make them look and taste better.
Some non-organic products such as milk come from G.M.O. which stands for Genetically Modified Organisms.
One of the chemicals that is put into non-organic products is pesticides. Pesticides kill any bugs that try to eat plants or fruits that are growing. Hypothesis I predict that the organic products will taste better than the non-organic products. I believe this will be the case because non-organic products have many chemicals which may affect their taste. Organic Blueberries
Non-Organic carrots Materials Make sure subjects are not allergic to any products that will be tested
Check expiration dates on all products
Research if any products that will be tested have been recalled by the F.D.A (Food and Drug Administration)
Wash fruit thoroughly Safety 10. Give your first subject two snack bags (one bag of organic blueberries and one bag of non-organic blueberries
11. Ask your subject to eat the fruit in both bags and ask them if they can tell the difference between the two.
12. Record results.
13. If they are able to tell the difference, ask them to tell you which one tastes better and record results.
14. Repeat steps six and seven with non-organic/organic popcorn, and non-organic/organic carrots.
15. Repeat these steps with nine other volunteers for a total of ten subjects.
16. Record all results and document on a graph/table. Procedure (continued) 1. Gather all materials.
2. Place 1 tablespoon of frozen organic blueberries in ten small snack bags.
3. Repeat this step with non-organic frozen blueberries for a total of twenty bags.
4. Repeat step number one with carrots for a total of forty bags.
5. Pop the “Jolly Time” organic popcorn on the microwave according to package directions.
6. Do the same for the non-organic “Jolly Time” popcorn.
7. Place one tablespoon of organic cooked popcorn into ten snack bags.
8. Repeat this step with the non-organic cooked popcorn for a total of twenty snack bags.
9. You will have a total of sixty snack bags filled with half non-organic and organic food products. Procedure Results I have tested ten subjects with blueberries, popcorn, and carrots.
Only nine of the ten test subjects could taste the difference in the organic blueberries and the non-organic.
Seven out of the ten test subjects could taste a difference in the organic popcorn and the non-organic popcorn.
Only five out of the ten test subjects could taste the difference in the organic carrots and the non-organic carrots. Conclusion My hypothesis was incorrect, non-organic products tasted better than organic products. Organic is better for you, unlike non-organic food, but non-organic tastes better. Non-organic tastes better because it has chemicals. I concluded that if you want to buy for taste, buy non-organic food. If you want to buy food for health reasons, you should consider buying organic products. An error that may have occurred was that the organic popcorn might have been overcooked. Future ideas could be, do organic food and non-organic food look the same? Or what can the chemicals inside non-organic products do to harm you? Well now you know that that nice shiny non-organic apple has a little secret. Controlled Variables: the amount of the product placed in each bag
Manipulated Variable: the product being tested (organic vs non-organic)
Responding Variable: individuals taste preferences will vary Variables Problem Can you tell the difference between organic and in-organic products by taste? Results (continued) Which one tasted better?
blueberries: organic-3 non-organic-7
carrots: organic-4 non-organic-6
popcorn: organic-2 non-organic-8
Based on these results, non-organic products tasted better. The Subjects The Test! Help! Credits I would like to give special thanks to my Mom, Dad, Aunts, Uncles, Brother, Grandparents, and all my Cousins.
A special thanks to my Uncle Richard for giving me a good laugh! Bibliography
