VCE Physics Scientific Investigation

What is the purpose of a scientific investigation in VCE Physics?

What are the key steps involved in conducting a scientific investigation?

• Formulating a research question, conducting background research, formulating a hypothesis, designing and conducting experiments, collecting and analyzing data, drawing conclusions, and communicating the results.

• Conducting background research, formulating a hypothesis, designing and conducting experiments, collecting and analyzing data, drawing conclusions, and communicating the results.

• Formulating a research question, conducting background research, designing and conducting experiments, collecting and analyzing data, drawing conclusions, and communicating the results.

• Formulating a research question, conducting background research, formulating a hypothesis, designing and conducting experiments, collecting and analyzing data, drawing conclusions, and communicating the results.

Explain the concept of independent and dependent variables in a scientific investigation.

• The independent variable is the variable that is not manipulated or changed by the researcher, while the dependent variable is the variable that is measured or observed to determine the effect of the independent variable.

• The independent variable is the variable that is manipulated or changed by the researcher, while the dependent variable is the variable that is measured or observed to determine the effect of the independent variable.

• The independent variable is the variable that is measured or observed to determine the effect of the dependent variable, while the dependent variable is the variable that is manipulated or changed by the researcher.

• The dependent variable is the variable that is manipulated or changed by the researcher, while the independent variable is the variable that is measured or observed to determine the effect of the dependent variable.

What is the importance of controlling variables in a scientific investigation?

• To increase the chances of error in the results

• To isolate and manipulate specific factors to determine their impact on the outcome.

• To make the experiment more complicated

• To introduce bias into the experiment

Describe the process of collecting and analyzing data in a scientific investigation.

• The process involves conducting surveys, analyzing the data, and drawing conclusions.

• The process involves formulating a hypothesis, collecting data, and presenting the findings.

• The process involves conducting experiments, collecting data, and drawing conclusions.

• The process involves defining the research question, collecting data, organizing and recording the data, analyzing the data using statistical methods, and interpreting the results.

What are the different types of errors that can occur in a scientific investigation?

• sampling errors, interpretation errors, and recording errors

• experimental errors, observational errors, and data errors

• systematic errors, random errors, and human errors

• measurement errors, calculation errors, and equipment errors

Explain the concept of reliability and validity in a scientific investigation.

• Reliability refers to the consistency and stability of measurements or results, while validity refers to the accuracy and truthfulness of the measurements or results.

• Reliability refers to the accuracy of measurements or results, while validity refers to the precision of measurements or results.

• Reliability and validity are the same concepts in a scientific investigation.

• Reliability refers to the accuracy and truthfulness of measurements or results, while validity refers to the consistency and stability of measurements or results.

What are the ethical considerations that need to be taken into account in a scientific investigation?

• Confidentiality, maximizing harm, lack of transparency, personal bias

• Informed consent, privacy, maximizing harm, avoiding conflicts of interest

• Informed consent, privacy, minimizing harm, avoiding conflicts of interest, integrity and honesty

• Transparency, minimizing harm, personal bias, integrity and honesty

Discuss the role of peer review in the scientific investigation process.

• Peer review is not necessary for scientific research.

• Peer review only focuses on the quantity of scientific research.

• Peer review is a time-consuming process that delays scientific progress.

• Peer review ensures the quality and validity of scientific research.

Explain the importance of communicating the results of a scientific investigation.

• To keep the results a secret and maintain exclusivity; to prevent others from benefiting from the research; to limit the advancement of scientific knowledge.

• To allow for review, replication, and building upon the research; to disseminate knowledge; to contribute to the scientific community; to inform the public about scientific advancements.

• To avoid criticism and scrutiny of the research methods and findings; to protect the reputation of the researcher; to maintain a sense of superiority.

• To confuse and mislead other scientists; to create a false sense of progress; to hinder scientific advancements.
