Make two pits...
In one, put some vegetable peels and in the other, put some polythene bags...
Both to be covered for approx. 3-4 weeks..
Observe after a day or two and note ur observations in tabular form...
You will observe after some days the organic material starts to decompose in the manure form(dark brown substance) whereas the plastic remains the same...
And after 3-4 weeks you will get a decomposed manure but plastic is the same
So we can conclude the organic materials are bio-degradable but plastic is non-biodegradable...
