The last few weeks Olivia, Hollie and I conducted an experiment on how Rye grass grows when watered with cold water, hot water, sugar water and salt water. Our prediction to start off this experiment was that the hot and cold water would continue growth like normal, maybe the hot would grow a bit slower. We expected the salt to not grow at all. We thought that because the plant is a land plant, not living by the sea where salt water is present, therefore it would die. The sugar we expected for the rye grass to grow more than usual, because of added nutrients for the plant. This experiment was our back up plan, because of problems gathering materials for our algae experiment. Now, for our results. The hot and cold water grasses grew normally. Very consistently. The salt and sugar water, didnt grow. At all, throughout our whole experiment! We concluded that temperature does not affect the growth of the rye grass, and that because of osmic pressure in the plant, and in the sugared water, it stunted the growth of the grass. the salt waters sodium took out the plants nutrients, and the bi carbonate messes with the plants ability to use photsynthesis. Causing the plant to die!
