Scientific Method
Observation: During the winter, you spread salt daily on your driveway to melt the snow. In the springtime, when the lawn begins to grow, you noticed that there is no grass growing for about 3 inches from the driveway. Furthermore, the grass seems to be growing more slowly up to 1 foot from the driveway.
Question:
Might grass growth be inhibited by salt?
Introduction:
The chemical components that make up salt are the fused elements of sodium and chloride (Editorial Board, 2012). If there is abundance or very little salts present in dissolve fluids, there could be interference with routine cell functions. Plants depend on water for fluids within the living cells. Too much salt disrupts the flow of the necessary fluids to get to the roots. In addition, a disruption of the photosynthesis process which depends on water particles to carry oxygen and hydrogen atoms throughout the plant becomes stagnant. The salt, mixed with snow and ice, melts down to a watery substance that contains high levels of sodium chloride.
Hypothesis:
The grass that has been saturated in salt will take longer to grow.
Prediction:
If my hypothesis is correct, then the outcome of the grass that was saturated with high levels of salt would grow much slower than the grass that was not exposed to salt.
Methods
In order to be consistent with the observations, mark off evenly with wooden steaks, three patches of grass 2 feet x 2 feet, starting from the edge of the driveway. Each section is touching the driveway. All three patches of grass are five feet away from each other. Measure all three section to ensure the height of the grass are even, so trim down to 2 ½ inches for each patch of grass.
In one bottle (1) add an inch in depth across the bottom with rock salt. In bottle (2) add ½ inch of rock salt across the bottom. In bottle (3)
