    What are the decomposition rates of different items?
  • hypothesis

    hypothesis
    I beleive that the apple will be most decomposed. I also think it will be about 45% of the way decomposed.
    orange 25% composition chip bag 10%
    cup 10% chip bag 5% cotton 2%
    paper 15% foil 1%
  • Materials and Equipment

    Materials and Equipment
    Consists of : shovels, wooden stakes, hamer, marker tape, rebar stakes, apple, orange, cup, paper, composition chip bag, chip bag, foil, and cotton.
  • Procedures

    Procedures
    On March 23rd, we dug 8-10 in. Then we buried each item in a seperate hole. We will document the changes of weather, tempature, wind, and humidity. As well as document the changes in the items when we dig them up after 9 weeks.
  • Weather/ weather description

    Weather/ weather description
    The weather is important to decomposition. It must be warm and humid enough for decomposition organisms to be very active.The weather today was sunny with temp. of 44 F, the high being 65 F, humidity 50%, wind 12 mph NE, and baro. press. 30.16 in.

    Weather
    todays weather was sunny with a temp. of 49 F, wind 5 mph NW, baro. 29.80 in, and humidity was 66%.
  • styrofoam

    styrofoam
    styrofoam takes around 50 years to decompose, it is mostly uneconomical, and its sources are widespread. I beleive it will be 10% decomposed by the end of the nine weeks.

    It was sunny with warm temp and high humidity
  • aluminum foil

    aluminum foil
    Aluminum foil takes a very long time to decompose, it is easily recycled though, and it has a large source third only to silicon and oxygen. I beleive it will be 2% decomposed by the end of the nine weeks.

  • sun chips bag

    sun chips bag
    The sun chips bag is made to decompose 100% in 14 weeks time when placed in a composite heap.I beleive it will be 55% decomposed.

  • chips bag

    chips bag
    The chips bag is a slow decomposition object. It is best to give it to a recyclinng company to recycle it properly.I beleive it will be 15% decomposed.

    Todays weather is partialy cloudy and windy but still warm.
  • Apple

    Apple
    The apple will decompose quickly I beleive. It is fine just to throw the apple away if you want, in fact if you wanted you could just put it in a garden or something and it would be fine. It will probably be 75% decomposed at the end of the nine weeks.
  • Paper

    Paper
    The paper has a quick decomposition rate and it is fine to recycle by mill braking and many other sorts of things.I beleive the paper will be 70% decomposed.
  • weather

    This weeks weather is sunny with cool to warm tempatures.

    This weeks weather is cool and cloudy with some rain and hail. It was however, sunny and warm later on.
  • Cotton

    Cotton
    The cotton is easy to get recycled you can just take it to a charity shop and they will take it of to be recycled.I beleive the cotton will be 45% decomposed.
  • Orange

    Orange
    The orange decomposes fine on its own though it does take longer than most other fruits to decompose all the way. I beleive it will be 70% decomposed by the end of the nine weeks.

    weather
    The weather this week is very sunny and HOT! It is certainly feeling like summer now! We also had some rain mixed in!
  • apple conclusion

    apple conclusion
    The apple is 95% decomposed. I was not surprised to find that the apple was decomposed the most. I was however surprised to see that it was so far along!
  • Foil conclusion

    Foil conclusion
    The foil was 0% decomposed which didnt surprise me. Foil is a very tuff substance when it comes to decomposing.I did think it would be a little bit more decomposed than it was but oh well, just a guess any way and I got close!
  • Paper conclusoin

    Paper conclusoin
    The paper is 20% decomposed.The paper was very surprising, I thought it would be far more decomposed than it was. It does however still fall down to 20% !
  • Orange conclusion

    Orange conclusion
    The orange is 90% decomposed. It was interesting to see how it decomposed so much like the apple. I figured it would be further behind the apple in the prosses but it proved me wrong!
  • reg. chips bag cunclusion

    reg. chips bag cunclusion
    The regular chips bag was 15% decomposed. I guessed exactly right on the decomposition rate of this! I was very happy about that!
  • sun chips bag conclusion

    sun chips bag conclusion
    The sun chips bag is 80% decomposed. It was more so decomposed than I thought it would be. I think its an interesting thing to see!
  • Styrofoam conclusion

    Styrofoam conclusion
    The styrofoam is 5% decomposed. I thought the styrofoam's decomposition rate was interesting to see. I thought it would be at least 10%
  • cotton conclusion

    cotton conclusion
    The cotton is 0% decomposed. I was surprised to see how well the cotton held together. I had thought that it would be 45%. I geuss that is so because its tightly packed together!
