1G6 SCI Science Process Skills

What is the first step in the scientific method?

• Analyze the data

• Make an observation or ask a question.

• Conduct an experiment

• Formulate a hypothesis

How do you measure the length of an object accurately?

• Estimate the length by eyeing it.

• Use a compass to measure the length.

• Use a ruler or measuring tape to measure from one end of the object to the other.

• Count the number of fingers it takes to cover the object.

What is a hypothesis?

• A hypothesis is a testable prediction about the relationship between variables.

• A hypothesis is a summary of research findings.

• A hypothesis is a proven fact about variables.

• A hypothesis is an untestable theory.

Why is it important to conduct experiments?

• It is important to conduct experiments to test hypotheses and gather empirical evidence.

• To create theories without testing them.

• To avoid making decisions based on data.

• To confirm existing beliefs without evidence.

What tools can be used for measuring temperature?

• Hygrometers

• Barometers

• Thermometers, infrared thermometers, thermocouples.

• Anemometers

What is the purpose of a control group in an experiment?

• To increase the sample size of the experiment.

• The purpose of a control group is to serve as a baseline for comparison in an experiment.

• To ensure that all variables are controlled during the experiment.

• To provide the experimental treatment to all subjects.

How can you ensure your observations are accurate?

• Ignore environmental factors

• Rely solely on intuition

• Use outdated instruments

• Use reliable instruments, calibrate them, take multiple measurements, control for variables, and document methods.

What is the difference between qualitative and quantitative data?

• Qualitative data can be represented as graphs and charts.

• Quantitative data is descriptive and non-numeric.

• Qualitative data is descriptive and non-numeric, while quantitative data is numeric and measurable.

• Qualitative data is always numeric and measurable.

What is a variable in an experiment?

• A variable is a constant that does not change.

• A variable in an experiment is a factor that can change and affect the outcome.

• A variable is a tool used to measure outcomes.

• A variable is the final result of an experiment.

How do you collect data during an experiment?

• Collect data by defining variables, using measurement tools, and recording observations systematically.

• Collect data by guessing outcomes and making assumptions.

• Use only personal opinions without any measurements.

• Ignore variables and focus solely on results.
