J.J. Thomson (Sir Joseph John Thomson, 1856-1940), who demonstrated in 1897 that "cathode rays" consisted of negatively-charged particles, later named electrons.
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.
manipulated variable
An artificial situation created by a scientist to observe the consequences of specific changes is called an experiment. In an experiment, the scientist manipulates variables to test hypotheses and determine the impact of those changes under controlled conditions. This method allows for the identification of cause-and-effect relationships in the natural world.
The scientist wants to design an experiment that will demonstrate the effect of the independent variable on the dependent variable. This idea is to show causality between the two.
A scientist should be patient and wait calmly for the result of the investigation or experiment.So he can finished or accomplish his work and always read to try again especially when things don't work out. For example: A scientist is working on an experiment and the result of it is taking to long and he tends to live the experiment.Not knowing if he will be successful to his experiment. So a scientist should be patient and try again if he doesn't succeed.
J.J. Thomson designed an experiment that allowed for the first successful detection of an individual subatomic particle, the electron, in 1897. This discovery was a crucial advancement in understanding the structure of atoms and laid the foundation for modern particle physics.
a scientist can do another experiment or change their hypothesis.
the answer is the scientist designs a scientific inquiry
The scientific theory should be changed.
Analyze the experiment to decide whether the results were flawed.
Many times, the scientist has a fair amount of confidence that the experiment will perform according to the prediction.
The tools that a scientist would use to conduct an experiment would vary greatly on the nature of the experiment.
An experiment.
Be clear about the purpose of the experiment.
plan the experiment
