Biodegradability Experiment

เวอร์ชันสำหรับพิมพ์Send by email

On October 7, 2011, the Junior High Science Class began an experiment to see which trash items were biodegradable. Something that is biodegradable can be broken down naturally by organisms.

The Process

We dug a hole 1m X 1m, 30 cm deep. It took us a few days.

We put left-over food, foil, plastic bags, juice boxes, and plastic bottles in the hole and left it for one month.

After one month, we re-opened the hole .

Conclusion

Most leftover food was decomposed except for the chicken bones. The other stuff didn’t biodegrade at all. From the result of the experiment, we now know the disposal problem with non-biodegradable items.
