My group did an expirement with rye grass. We tested different waters. We had salt and sugar water. Five vials for salt and five vials for sugar. One vial for each, salt and sugar group was ragular tap water. Each vial started with 20 ml of tap water. Then each vial we would add five ml of the product. So for salt, vial one just water and vial two had 5ml salt. Vial three 10ml salt. Vial four 15ml salt. Vial five 20ml salt. Then we added the same amout of sugar to the other five vials! I learned a lot of information about osmosis and what it was and how its a big part of the plants life. I learned why the salt effected the rye grass. "Osmosis." Wikipedia.
