||We learned that the plants suck the water up, but it has to be submerged in order for the salt to make it pliable.
||The question we came up with is: Do minerals have an effect on celery sticks?
||Yes, minerals will have an effect on celery.
||Materials: Carbonated Mineral water, Tap water, Distilled water, 10% solution of salt water, 4 10-15 centimeter celery sticks, 4 glass beakers or cups.
First measure the length, width, thickness, and weight of the celery sticks. Make some observations on them. Then pour each type of water into a separate glass, put the celery in, one per glass. Let them sit in a cold dark place for 16 hours. Take them out and examine them. Measure their length, width, thickness, and weight. Mark these things in a notebook.
||The salt water was limp and flexible. The tap, mineral, and distilled water were all slightly bent. The different minerals had a slight affect on the celery. Other experiments could try to find what types of mineral combinations affect celery bending, or how much minerals are needed to affect celery bending.
