Yes, Jan Baptist van Helmont's experiment supported his belief that plants derive their substance primarily from water. He conducted a study in which he planted a willow tree in a pot of soil and only watered it, later measuring the tree's growth and the soil's mass. His findings indicated that the soil's weight remained largely unchanged while the tree grew significantly, leading him to conclude that water was the main source of the plant's mass. However, his conclusions were limited by the absence of understanding regarding air and nutrients, which also play crucial roles in plant growth.

The results of an experiment do not support the hypothesis that the experiment was designed to test Was the experiment a waste of time?
The purposes of testing a hypothesis is to test it. Pass or fail, the experiment is a "success" if it does that - tests the hyposthesis. If the results don't support the hypothesis, then that is valuable data that helps you either abandon or refine the hypothesis.

Did the result of the experiment support van Helmont and beliefs?
The result of the experiment did not support van Helmont's beliefs. Instead of coming from water, the increase in the plant's mass was due to the absorption of nutrients from the soil.

A scientist who performs an experiment has no idea what the outcome of the experiment is going to be true or false?
True. In an experiment, a scientist formulates a hypothesis, designs the experiment, collects data, and then analyzes the results to draw conclusions. The outcome of the experiment is not known beforehand, and it is the results of the experiment that will either support or refute the hypothesis.

What can scientists do if the results of an experiment do not support a hypotheses?
They should try again. Then check very carefully and see if they did the experiment correctly. They may have to change their hypothesis.

What is the term for the answers provided by an experiment?
"Data" is the numerical results provided by the experiment. "Conclusion" is the deduction we make from the experiment, whether it's a verification of an equation, or a theory, or anything else.
