Measurement and rationale for the growth of a willow tree is Van Helmont's experiment.
Specifically, Jan Baptist van Helmont (1580-1644) was a Brussels-born scientist. He was an astute observer of objects and processes. One of his famous experiments was centered on the five-year study of the growth of a willow tree (Salixspp). His conclusions of a 164-pound weight gain due to the intake of water through the roots and soil were prefatory to understandings of the conservation of mass even though he ignored the role of atmospheric carbon dioxide.

What was Jan van helmonts conclusion?
make the plants grow
What was Van Helmont's hypothesis in the willow experiment?
To test his hypothesis
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.
Can you do an experiment with a van de graaff generator?
You can light a fluorescent bulb
What happens to all oxygen molecules that originated from carbon dioxide in the van niel experiment?
stuff happens
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.
What was wrong with helmonts conclusion that when plants grow their increase in mass comes from water?
Increase of mass from water. Actually increase in mass is the result of increase in organic matter instead of water.
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.
How fair was van helmont experiment?
yes, it was partially fair becaues he only proved that 'water' was basic element but soil and air was also an basic element.
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
When do you end your experiment?
Life is an experiment. When you die, that experiment is over.
