A student conducted an experiment to test whether talking to plants would help them to grow faster. The student talked to one gr
oup of plants and hand watered them. The student did not talk to the other group of plants and used sprinklers. After three weeks, the plants that were spoken to showed much more growth than the plants that were not. Based on the results of this experiment, which is the best conclusion? Talking to plants may or may not help plants grow faster because three weeks is not enough time to tell. Talking to plants may or may not help plants grow faster because the amount of water given was likely different for each group. Talking to plants does not help plants grow faster because the experiment did not involve enough groups of plants to determine this. Talking to plants does help plants grow faster because those plants showed more growth.
The answer I believe would be talking to plants may or may not helps plants grow faster because the amount of water given was likely different for each group. I say this because there are more than one manipulated variables. (Each experiment should only have one manipulated variable to really be able to come to a conclusion) The student wants to see if talking to the plant will help. But the student also used different watering methods. So there was more than one manipulated variable. This can not give a good enough result because we do not know which affected the plant- the talking or the watering method/amount.
