My hypothesis was that the carrots would be the best decomposer. The results showed the carrots decomposed better than apples or bananas.

Carrots decomposed more completely because they were chopped smaller when fed to worms, the moisture level was balanced better through project and the worms got bigger and thrived in the carrot bin. More micro organisms and worms helped break down the carrots faster.

I classified the healthiest bin as the one that had the darkest soil (compost available), the worm weight (Higher numbers are better) and more eggs and larva.

I’m concerned because I did not have as many worms at the end as I expected. I started with 8 oz per bin and had the following at the end of the project:

Carrots worm weight: 1 oz

Apples worm weight: 3 oz

Bananas worm weight: ½ oz

In conclusion I think if we all compost we can have a positive impact on the environment. Composting reduces waste and improves soil quality that helps plants grow. In turn the plants help clean our air.

   I had some unanswered questions, I plan to ask a worm expert (worms at work) the following questions:

1. Will worms reproduce better if they have a bigger variety of food?

Answer: Different nutrients in foods.

2. Why do you think that the carrots decomposed to make the healthier soil?

Answer: Because the pieces were smaller (smaller pieces easier to break down instead of big pieces).

3. Did the carrots have something in them that worms like? The sweetness in them they like, but apples are sweeter.

4. Do worms have a die off season and a reproduce season? They will reproduce more in spring.

Easier with more bacteria to help decompose.

5. Is there something that I did wrong? The wetness too wet or too dry) or food amount (too little or to much).

React to vibrations.
