Recycled water and plant growthFeatured science projectScience project video


The hypothesis that  radish plants  grow more quickly when watered with recycled water is proven to be true.

Recycled water can be used for many applications and helps to conserve our fresh water resources. It can be used in industrial processes, irrigation, watering public parks and gardening. In some countries like Singapore and in Orange County, California, recycled water  is given a more advanced treatment and used as drinking water.

Also consider

Try to repeat the science fair project using different types of plants. Observe if these plants react similarly to the radish.

The science project experiments can also be repeated to compare the rate of seed germination when recycled water is used.
