Why did the mass of the willow tree increase by such large amounts?
Van Helmont's conclusion after his experiment was after the 5 years the amount of soil weighed the same amount, and that the willow tree gained weight by the water that was being added daily. He was wrong because the willow tree got its nutrients and energy not only from water, but also from Co2. This is relevant to what we now know because Van Helmont thought that the willow tree would use material from the soil to grow, but it was actually the water and the CO2 which made the tree grow. -Lily Gallo
Who came up with the red queen's hypothesis and in what year?
Leigh Van Valen. 1973.
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.
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.
What conditions relate to the research of van Helmont?
He grew a willow tree in a carefully weighed amount of soil. He noticed that little of the soil was consumed, but that the weight of the tree greatly increased. He concluded that the extra weight came from the water. His willow tree experiment was one of the first to use quantitative measurements. Van Helmont wanted to understand digestion chemically, believed all substances could be reduced to air and water, and thought that acid/base reactions were fundamental.
What was Jan van helmonts conclusion?
make the plants grow
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 van helmont's hypothesis?
Van Helmont's hypothesis was that plants gain most of their biomass from water, rather than from soil as previously believed. He conducted an experiment which involved growing a willow tree in a known amount of soil and watering only with rainwater, and found that the tree's mass significantly increased while the soil mass decreased only marginally, leading him to conclude that water was the main source of a plant's growth.
What is Van Helmont's experiment?
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 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.
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 did the experiments of van Helmont Priestley and Ingenhousz reveal about how plants grow?
Van Helmont proved that soil was not responsible for a tree's increase in mass by doing an experiment with a willow tree. He found that the tree grew by 74.4 kg without a comparable decrease in the soil's mass. Priestly discovered that plants release a gas into the air that supports combustion. Ingenhousz discovered that the plant in Priestley's experiment is depended on light and that the gas released by the plant is oxygen. Carbon dioxide was the source of carbon in plants.
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?
