7SCI-Q1-T1-Quiz 2- The Nature of Science

Which scientific skill involves grouping together items that are alike or have shared characteristics?

• Evaluating

• Inferring

• Classifying

• Observing

What does the scientific skill of inferring involve?

• Making a statement about future events

• Explaining or interpreting observations

• Comparing observations and data

• Using senses to gather information

What is the role of ethics in scientific attitudes?

• To encourage creativity

• To ensure honesty and knowing right from wrong

• To promote bias in experiments

• To enhance curiosity

In an experiment, what is the role of the independent variable?

• It is the outcome variable that changes in response to other variables.

• It is the variable that the researcher changes or manipulates.

• It is the variable that remains constant throughout the experiment.

• It is the variable that is affected by personal opinions.

How does scientific reasoning help in drawing conclusions?

• It relies on personal feelings and biases.

• It uses evidence and logic to draw objective conclusions.

• It involves making assumptions without evidence.

• It depends on changing all variables in an experiment.

What is the importance of using standard units in scientific measurements?

• It allows for more creative experiments.

• It helps in repeating and reproducing experiments accurately.

• It makes experiments more fun.

• It reduces the need for precise measurements.

How do scientists ensure the reliability of their measurements?

• By making measurements as quickly as possible.

• By ensuring measurements are both accurate and precise.

• By using only one measurement for each experiment.

• By avoiding the use of standard units.

What is the relationship between 1 kilogram and grams?

• 1 kg = 100 g

• 1 kg = 1,000 g

• 1 kg = 10,000 g

• 1 kg = 100,000 g

Why is it important to evaluate measurements for precision and accuracy in science?

• To make experiments more entertaining.

• To ensure measurements are close to the actual value.

• To reduce the number of experiments needed.

• To avoid using math skills.

What is the formula to calculate percent error?

• (True value - Experimental value) / True value × 100%

• (Experimental value - True value) / Experimental value × 100%

• (Experimental value - True value) / True value × 100%

• (True value - Experimental value) / Experimental value × 100%
