Collect some kitchen waste and some plastics. Take two pot filled with soil dig two small pits. Label them A and B. In pit A put the kitchen waste and cover it with soil. In pit B put the plastics and do the same. After 7-8 weeks dig the soil. In pit A you will find black fertile humus. It is the decomposed waste. In pit B you will find that that plastic is in the same state. From this activity we can conclude that kitchen waste which is organic as well as biodegradable since it decomposed and plastic is non biodegradable since it did not decompose.
