Plant growth
 How do pollutants affect the plant growth?
Introduction:

Water impurities generally include minerals, viruses, bacteria and other organic materials. Sewer water from homes and industries contains a large variety of such water impurities. Currently sewer water is going through some initial treatment to remove some impurities and then it is discharged into rivers and oceans. 

If water impurities are not harmful to the plants, part of such water can be used for irrigation and watering gardens. 
 
 Project description:
In this project you will perform experiments to find out how water impurities affect plant growth. You will start from planting seeds so all your plants will have the same age and conditions.
