The purpose of this experiment was to determine whether plants exposed to varying amount of salt water (ocean water) will grow differently than those exposed to regular water. To carry out this experiment, four groups of cabbage plants were planted. One group was watered using only water with 36 grams of ocean salt per liter of water (the actual amount in sea water). Another group was watered using only water with 18 grams of ocean salt per liter of water. The third group was watered using only water with 9 grams of ocean salt per liter of water. The last group was watered with regular water, which contained no ocean salt. This final group was used as a control.
After giving the plants sufficient time to grow, it was discovered that the plants in the groups exposed to regular water grew to be larger and more healthy than those exposed to ocean water. The plants exposed to water with 36 grams of salt per liter of water did not grow at all. Those exposed to the water with 18 grams of salt per liter of water did not grow well either. The average height for plants in that group was too small to be measured. The plants exposed to water with 9 grams of salt per liter grew much more poorly than the plants in the control group. It was discovered that cabbages grow best in regular water, which has no salt in it.
