My Prediction

What I think will happen?

I predict that the apple will take 4 weeks to decay. I think it will begin to smell and attract scavengers and decomposers.

1) We want to know how long it take for an apple to decompose?

1. Place 1 cup of soil inside the plastic container2. Add the apple inside the soil, push to the front so you can view the apple.3.add 1/4 cup of water to the soil.4.Place the cling wrap over the container.5. using a sharp pencil poke 5 small holes into the cling wrap.

Results

What happened & Why?

1. Cup of soil2. 1/4 cup of water3. 30cm of cling wrap4. 1 apple5. 1 clear container

At the end of the 4 weeks we found that the apple decayed almost completely. Using magnifying glass's we found lots of little bugs and flies crawling through the soil. They are scavengers and decomposers. We didn't find the apple to smell. Out predictions were mostly correct, although i think next time we will use a thermoemter to track the temperature in which the apple decays.
