A Scientific Method Quiz- I

Explanation
The scientific method is a systematic approach used by scientists to investigate and understand natural phenomena. It consists of six steps: observation, research, hypothesis, experiment, analysis, and conclusion. Each step builds upon the previous one, allowing scientists to gather and analyze data in a logical and organized manner. Therefore, the correct answer is 6.

Explanation
Hypothesis refers to a guess or assumption made based on limited evidence or information. It is a tentative explanation that can be tested and further investigated through experiments or research.

Explanation
The first step in the scientific method is to state the purpose of the experiment. This is important because it helps to clarify the objective of the research and provides a clear direction for the entire scientific process. By stating the purpose, scientists can establish a hypothesis and design an experiment to test it. This step sets the foundation for the entire scientific investigation and helps to ensure that the research is focused and meaningful.

Explanation
The last step in the scientific method is to give advice to other scientists. This step involves sharing the findings and conclusions of the research with the scientific community. By providing advice, scientists can contribute to the collective knowledge and understanding of the topic, and also help guide future research and experiments. It promotes collaboration, peer review, and the advancement of scientific knowledge as a whole.

Explanation
The step that involves creating a chart or graph is analysis. This is because analysis involves examining data and information in order to identify patterns, trends, and relationships. Creating a chart or graph is a common way to visually represent and analyze data, allowing for easier interpretation and understanding of the information.

Explanation
In experimental research, a controlled variable is a factor that is intentionally kept constant throughout all trials. This is done to ensure that any observed changes or effects are solely due to the manipulated independent variable and not influenced by other variables. By controlling variables, researchers can isolate and study the specific impact of the independent variable on the dependent variable. Therefore, the correct answer for the given question is "Controlled."

Explanation
It's an experimental group that gets the variable being tested.
