device and activity to show that organic waste is biodegradable, while plastic is not
please write that this is material, conclusion and observations
Answers
Take two beaker A and B.
Put moist soil in the both.
Put organic waste in the beaker A and Plastic in beaker B.
After a week or two you will find that the organic waste are decomposed while the plastics are not.
This proves that organic waste is biodegredabe and plastic is not.
2 It is a well known phenomenon that organic waste materials are biodegradable but plastic waste materials are non biodegradable.
To prove this phenomenon ,we can do the activity mentioned below.
Activity procedure:
In a grassland where the soil is soft and easy for digging,we have to make two medium sized holes.
Then in the first hole ,we have put the organic waste materials and in the second hole we have to put the plastic waste materials.
After that,we have to close the mouths of those holes with the help of soil.
Then we have to wait for 2-3 months.
Observations:
The organic waste materials will be dissolved in the soil but the plastic waste materials are still intact.
This activity proves that the organic waste materials are biodegradable and plastic waste materials are non-biodegradable.
