Water Pollution

Water pollution is an excellent subject to explore in a science fair project. Living things cannot live without water and therefore life on our planet.

PURPOSE

The purpose of this experiment was to determine the effect of water acid levels (pH) on the growth of radishes.

I became interested in this idea when I found an article in the newspaper on how acid rain affected a country and ruined their crops.

The information gained from this experiment could help society to understand ways that acid rain affects plants. This could act as a warning to people and prevent future problems.

HYPOTHESIS

My first hypothesis was that the radishes watered with a pH level of 3.0 would be most negatively affected.

My second hypothesis was that the radishes watered with a pH level of 6.0 would be least negatively affected.

I based my hypothesis on the fact that the lower the pH level, the higher the acid level. Acid rain is most severe when the acid level is highest and the pH is lowest.

EXPERIMENT DESIGN

The constants in this study were:
• The amount of soil in each container
• The type of soil used in each container
• The amount of water received
• The amount of light received
• The date planted
• The type of radish, cherry belle
• Growing temperature
• The date on the seed packet

The manipulated variable was the pH level of the water.

The responding variable was the radish growth.

To measure the responding variable at the end of my experiment, I pulled all of the radishes out of the soil, took off the excess soil, and weighed all of the radishes in the same pH group at the same time, and then I divided the weight by the number of radishes to find the average weight of a radish.

MATERIALS

QUANTITY ITEM DESCRIPTION
2 Planting trays containing 72 cubicles
1 Package of radish seeds
2 light fixtures
2 60-watt light bulbs
1 package potting soil
1 syringe
1 roll of masking tape
5 milliliters of water
