What is Saltwater's Effect on Wheat Grass Plants? (page 2)

based on 34 ratings
Author: Aimee B.

Hypothesis

The expectation for this experiment is that the plant with the most amount of salt will wilt first. Also that the control plant will survive the longest, out of the four plants, according to:

Experimental Procedure

Step 1:Obtain plants

To start this experiment you must have at least four plants then label them plant A, plant B, plant C, and plant D. In this case, the plant, wheat grass was used. Three plants were watered with saltwater: plants B, C, and D while plant A will be the control. A control is like the original, for this instance, water is the control because it is the base of saltwater.

Step 2:Figure out the formula for the plants.

All plants are watered with ¼ cup tap water every day.

For example: Plant B is watered with ¼ teaspoon iodized salt, plant C is watered with ½ teaspoon iodized salt, plant D is watered with 1 teaspoon iodized salt, and plant A is the control and is watered with ¼ cup tap water only and no iodized salt.

Step 3: Record the data

Each day the individual plants were measured by height using a ruler, and the data was recorded in a notebook under labels: A, B, C, and D noting the date.

Analysis

The interpretation of the data collected during the experiment is that: The more salt that is exposed to the plants roots, the more the salt dehydrates the plants, therefore causing the plants to die, though most gardeners water their plants with regular tap water, the plant that was the control was watered with no salt water, yet it still wilted.

Conclusions

This experiment showed that watering plants with any amount of salt water inhibits the growth and life of a plant by dehydrating it. The hypothesis did support the experiment, as predicted, the control plant did live the longest, and the plant with the most salt intake was the first to wilt.
