In a controlled scientific experiment, a scientist systematically manipulates one or more independent variables while keeping all other variables constant to isolate the effect of those changes. This allows for the reliable observation of cause-and-effect relationships. The experiment typically includes a control group for comparison, ensuring that any observed effects can be attributed to the manipulated variable. Data collected during the experiment is then analyzed to draw conclusions.
What else can I help you with?
What are two types of scientific investigations that scientist use when a controlled experiment is not practical?
When a controlled experiment is not possible or practical, two types of scientific investigations are observation and modeling.
How do scientists develop scientific explanations about subjects that are impossible to study through controlled experiment?
Scientist use models
A scientist performs an experiment The results of the experiment disagree with a scientific theory The scientist repeats the experiment several times and gets the same results The scientist then?
The scientific theory should be changed.
After the scientist makes a hypothesis they perform a to collect data?
the answer is the scientist designs a scientific inquiry
What is a Test of hypothesis under controlled conditions is?
Testing a hypothesis under controlled condition is a scientific experiment.

What is a controlled experiment valuable to a scientist and why?
if something goes wrong they wont get the experiment right so it wont be a controlled experiment
A controlled experiment allows the scientist to isolate and test?
A controlled experiment allows the scientist to isolate and test a specific variable by keeping all other variables constant. This helps to determine the direct impact of the variable being tested on the outcome of the experiment. Controlled experiments are essential for establishing cause-and-effect relationships in scientific research.
Do you have to be a scientist to do science?
You do not have to be a professional scientist to do science. Anyone can perform a scientific experiment or make a scientific observation.
Why is a controlled experiment valuabl e to a scientist?
It gives the scientist something to compare their results to.
After the scientist makes a hypothesis they perform a to collect data?
the answer is the scientist designs a scientific inquiry
What is a Test of hypothesis under controlled conditions is?
Testing a hypothesis under controlled condition is a scientific experiment.
What 2 things does a scientist do in the fourth step of the scientific method?
In the fourth step of the scientific method, which is typically the "Experiment" phase, a scientist conducts experiments to test their hypothesis. This involves designing a procedure, collecting data, and ensuring that the experiment is controlled to isolate the variables of interest. The scientist then analyzes the collected data to determine if the results support or refute the hypothesis.
A scientist does an experiment The results of the experiment disagree with a major scientific theory What should the scientist do?
Analyze the experiment to decide whether the results were flawed.
