How is technology defined in relation to science?

• Technology is a branch of science.

• Technology is the study of natural phenomena.

• Technology is the application of science for practical purposes.

• Technology is unrelated to scientific principles.

Why is it important for students to follow safety precautions in the laboratory?

• Safety measures can slow down the experiment process.

• Safety precautions are only necessary for chemistry labs.

• It is important for students to follow safety precautions in the laboratory to prevent accidents and ensure a safe working environment.

• Following safety precautions is optional for experienced students.

What is a physical quantity?

• A measurable property of a physical system expressed numerically.

• A theoretical concept without numerical representation.

• A non-measurable characteristic of an object.

• A subjective opinion about a physical system.

In what unit is a physical quantity measured?

• Amperes and volts

• Units such as meters, kilograms, seconds, etc.

• Degrees Celsius and Fahrenheit

• Liters and gallons

Name one basic physical quantity and its symbol.

• Temperature (Θ)

• Length (L)

• Mass (M)

• Time (T)

What is the first step in a scientific investigation?

• Make an observation or identify a problem.

• Conduct an experiment

• Analyze the data

• Formulate a hypothesis

What do you do after carrying out an experiment?

• Analyze the data and document the findings.

• Share the results with friends immediately.

• Ignore the results and move on.

• Repeat the experiment without changes.

Why is writing a report important in scientific investigations?

• Reports are only for academic purposes, not practical applications.

• Writing a report is important because it ensures transparency, reproducibility, and effective communication of scientific findings.

• Writing a report is a waste of time in science.

• Reports are only necessary for published research.
