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.
When ou begin an experiment why should you create a table to a record your data?
Easy way to record, acceptable way to show findings, looks more professional than simple notes, shows rises/falls and if you are in school often by looking at the table you van work out why you did the experiment in the first place
What is a conclusion in a science experiment?
A Conclusion is the opinion formed after reviewing the evidence of your experiment. Conclusion also means the results of your hypothesis. ex: My hypothesis is most people drive a mini van than a jeep. My conclusion is most people drive a jeep than a mini van. so it's kind of the answer to your hypothesis but not all the way through though.
What is an inependent variable?
If I am not mistaken, the question should be "What is an independent variable?" The answer is this: An independent variable is a variable whose results are independent of all the other variables measured in the data sets/experiment. For an exaggerated example, if one were to perform Van de Graff Machine experiment where the values measured are Static Energy, Time, and The Number of Stars Present in the Sky, one would be likely to find the Statics Energy and Time would have a direct relationship whereas The Number of Stars Present in the Sky would have no relationship to Static Energy or Time.

Who are three scientists that contributed to our knowledge on photosynthesis?
Three scientists that contributed to our knowledge on photosynthesis are: Jan Ingenhousz, who discovered the role of sunlight in photosynthesis. Melvin Calvin, who elucidated the Calvin cycle, the process by which plants fix carbon dioxide during photosynthesis. Rudolph A. Marcus, who developed the theory of electron transfer reactions in photosynthesis, explaining the mechanism by which plants convert light energy into chemical energy.

Why was the experiment of James van helmont important?
The reason this experiment was important is because he wanted to find out if there was any other intake besides water and soil and there was and it was carbondioxide so it was important to find out carbondioxide.
Did van Helmont's experiment supports or disprove Aristotle's hypothesis?
His data contradicted Aristotle's hypothesis that a plant gains mass from soil.
