Activity on biodegradable and non-biodegradable substances

Aim:  To study Biodegradable and Non-biodegradable substances

Materials Required: Two pots, soil, plastic, polythene, aluminum foils,  canes, plants & animal waste, waste papers
Procedure:-
1.     Take two pots  half filled with soil,
2.     label them – Biodegradable and Non-biodegradable,
3.     Put plastic polythene, aluminum foils in non biodegradable pot.
4.     Put plant and  animal waste in – Biodegradable pot
5.     Record changes occur in these pots at least for 6 days
6.     Take images showing  the top view
                                         Non- Biodegradable substances



                                                           Biodegradable substances                                                                    
Observations:
1.     No change in the Non- biodegradable pot
2.     Bio degradable substances break down naturally.
Comments
1.   Biodegradable waste is waste that can break down by biological processes into natural components and be recycled naturally by the action of bacteria or other saprophytes. Examples are old vegetables / food, paper, cardboard, deceased animals, and phyto plastics (special plastics that break down when exposed to the sun after some time) etc.




2.   Non biodegradable waste is waste that does not break down into natural components and exists in the environment for a long time or may harm the various members of the eco- system.. Examples would be tyres, plastics, electronic components, metals etc.
