Parts Of An Experiment

A hypothesis is an educated guess because it is a proposed explanation or prediction based on limited evidence or knowledge. It is not a proven fact but rather a statement that can be tested through further research or experimentation. A hypothesis is formed by observing a phenomenon or problem, gathering relevant information, and making an educated guess about the possible explanation or outcome. It serves as a starting point for scientific investigations and allows researchers to formulate specific questions and design experiments to gather evidence to support or reject the hypothesis.

This answer is correct because it accurately states that the given steps, "state the problem, research, hypothesis, test your hypothesis, analyze your data, conclusion," are indeed a way to remember the steps of an experiment. The mnemonic device of using the phrase "some running horses trample annoying cats" helps to remember these steps in order.

The statement "An dependent variable changes on purpose" is incorrect. A dependent variable is a variable that is being measured or observed in an experiment, and it is not intentionally changed. It is the variable that is affected by the independent variable, which is the variable that is intentionally manipulated or changed in an experiment. Therefore, the correct answer is False.

The last step of an experiment is to communicate the results. After conducting the experiment and analyzing the data, it is important to share the findings with others. This could be done through writing a report, presenting the results to a group, or publishing the findings in a scientific journal. Communication allows other researchers to learn from the experiment and build upon the knowledge gained. It also helps to verify the results and ensure that the experiment was conducted properly.

The correct answer is to state the problem, conduct research, form a hypothesis, analyze the data, and draw a conclusion. In an experiment, the first step is to clearly define the problem or question that the experiment aims to address. Next, background research is conducted to gather information and understand the existing knowledge on the topic. Based on the research, a hypothesis is formulated, which is a proposed explanation for the problem. The experiment is then carried out, and the data collected is analyzed to determine if the hypothesis is supported or not. Finally, a conclusion is drawn based on the analysis of the data, which helps to answer the initial problem or question.
