False
When conducting an experiment, a careful guess is referred to as a hypothesis. A hypothesis is an educated prediction about the relationship between variables that can be tested through experimentation and observation. It serves as a foundation for scientific investigation and guides the research process.
Conducting an experiment involves systematically testing a hypothesis through controlled procedures to observe and measure outcomes. This process typically includes defining variables, establishing a control group, and collecting data to analyze results. The goal is to draw conclusions about the relationship between variables and contribute to scientific knowledge. Proper documentation and reproducibility are essential to validate the findings.
When conducting an experiment using the scientific method, the scientist should first formulate a clear hypothesis based on observations. Next, they should design and conduct a controlled experiment to test this hypothesis, ensuring that variables are properly managed. After collecting and analyzing the data, the scientist should draw conclusions and communicate the results, which may lead to further experimentation or refinement of the hypothesis. This iterative process helps advance scientific knowledge.
In a hypothesis, variables are typically classified into two main types: independent and dependent variables. The independent variable is the one that is manipulated or controlled to observe its effect on the dependent variable, which is the outcome being measured. Additional variables, such as controlled variables, may also be included to minimize the impact of extraneous factors. Together, these variables help structure an experiment or study to test the validity of the hypothesis.
In a scientific experiment, a variable is any factor or condition that can be changed or controlled to test its effects on the outcome. Variables are typically classified into three types: independent variables, which are manipulated by the researcher; dependent variables, which are measured and observed; and controlled variables, which remain constant to ensure a fair test. Properly managing these variables is crucial for obtaining reliable and valid results.

The procedure that tests a hypothesis by collecting information under controlled conditions is called an experiment. In an experiment, researchers manipulate one or more variables to observe the effects on the outcomes of interest. This controlled setting allows researchers to make conclusions about the relationships between variables.

To start a hypothesis for a scientific experiment, you need to make an educated guess about the relationship between two variables. This guess should be based on prior knowledge or observations.
an experiment to test a scientific hypothesis in which the variable component is controlled, not random, eg In an experiment that measures volume vs time to boiling, the volume, being the indirect variable, is measured.
In a hypothesis, variables are typically classified into two main types: independent and dependent variables. The independent variable is the one that is manipulated or controlled to observe its effect on the dependent variable, which is the outcome being measured. Additional variables, such as controlled variables, may also be included to minimize the impact of extraneous factors. Together, these variables help structure an experiment or study to test the validity of the hypothesis.
Controlled variables are quantities that must remain constant.
The third step of the scientific method involves conducting an experiment to test the hypothesis formulated in the second step. In this step, researchers manipulate variables and observe the outcomes to determine if there is a cause-and-effect relationship as predicted by the hypothesis.
The research question or hypothesis being investigated determines what will be tested in a scientific experiment. Researchers design experiments to test specific variables or relationships in order to answer their research questions and gain new insights into the natural world. The experiment is carefully controlled to isolate these variables and draw meaningful conclusions.
