What was the living tree experiment?
The "living tree" experiment was a scientific study performed originally by Jan Baptiste van Helmont (1580-1644) and thereafter repeated by several other scientists in the decades and centuries following. Van Helmont measures the weight of the tree at the start of the experiment (five pounds) as well as the weight of the soil (200 pounds). After five years of regularly watering the tree, van Helmont noted that the soil only lost about 2 ounces of weight while the tree weighed an astonishing 164 pounds. He concluded that because the tree did not gain all this weight from the soil, it must have gained it from the water intake. Although we now know that plants gain much of their mass from photosynthesis/carbon dioxide as well as soil, van Helmont's experiment has been lauded as an early example of strict attention to detail and experimental controls.
What scientist measured the mass of the soil in which a plant grew?
Van Helmont
How could you improve the experiment to reduce the effect of anomalous results?
repeating it
What do you put in an evaluation in science?
In an evaluation you put what you need to improve on the next time you do an experiment.
After you reach a conclusion about an experiment you may find you need to experiment more.?
It is certainly possible. The conclusion from your experiment may prove to be tentative and you may need to design a better experiment to improve the reliability of the conclusion, or the experiment may suggest alternatives which you may wish to explore. Most of science is about that: an experiment leads to conclusions. Further experiments result in refinements to the conclusions and, occasionally, to the replacement of earlier theories with new models.

Which scientist concluded that most of a growing plants mass comes from water?
Jan Van Helmont. in his 5-year experiment he planted a seedling in soil and watered it. it grew to a small treegaining 75kg. mass of soil didn't change. since water was all he added, he concluded it was from the water. - from Prentice Hall Texas Biology Book (9th grade)
