Four valence electrons termed as tetravalency.

1. By sharing my scientific knowledge on plastics and their affects with my parents relatives and friends to make them aware of plastic pollution .
2. I can help by teaching them how to avoid harmful plastics by searching for the resin code.
3. By educating them about the new rules and how important is to stop one-time use plastics.

Carbon is insoluble in water. But some of its compounds-are soluble in water and other solvents.
Eg: Ethanol and CO₂ are soluble in water.

Plastic in our everyday life can be harmful for two reasons .
1. Some types of plastics contain chemicals that are harmful to our health .
2. Lot of plastics are designed to be used just one time.
This use and throwaway plastics causes pollution to the environment.

1. We should not litter the environment by throwing plastic items.
2. We must not use thermocol (resin code # 6 PS) for our school projects.
3. Do not use one-time use or throwaway plastics like plastic bags, teacups, thermocol plates and cups, and plastic straws.
4. Do not burn plastics since they release toxic gases that are harmful to our health and contribute to climate change.
5. Burning PVC plastic releases dioxins which are one of the most dangerous chemicals known to humans.
6. Do not eat hot or spicy food items in plastic containers.
7. Segregate plastic waste and hand this over to the municipal authorities. So that it can be recycled.
8. Educate at least one person per day about how to identify the resin codes and avoid unsafe plastics.

1. Plastics take a very long time to fully break down in nature.
2. The microbes that break down plastic are too few in nature to deal with the quantity of plastics we produce.
3. A lot of plastic does not get recycled and ends up polluting the environment.
4. Some types of plastics contain harmful chemical additives that are not good for human health.
5. Burning of plastics releases toxic gases that are harmful to our health and contribute to climate change .
6. One-time use and throwaway plastics end-up littering and polluting the environment.

The three unsafe plastics are PVC (resin code # 3) PS (resin code # 6 also commonly called thermocol) and PC/ABC (resin code # 7)
PVC - Polyvinyl Chloride plastics:

It is the most toxic plastic. Burning PVC releases dioxins, one of the most toxic chemical known to humans.
PS - Polystyrene plastics:

1. Styrene is a building block of this plastic and may cause cancer .
2. It takes very long time to break down. (ie.) 100 - 1 million years .
3. Higher amounts of toxic styrene leak into our food and drinks when they are hot or oily.
PC - Polycarbonate plastics:
1. PC plastic contains Bisphenol (BPA)
2. BPA leaks out of PC products used for food and drinks .
3. BPA increases or decreases certain hormones and changes the way our bodies work
ABS - Acrylonitrile Butadiene Styrene
1. Styrene causes, problems for our eyes, skin, digestive system and lungs .
2. Studies show toxic chemicals leak from this plastic.
