Which of the following is an inference?

• The sky is blue.

• The plant's leaves are green and moist.

• The dog must be hungry because it is whining.

• The temperature is 30°C.

How can evidence be used to support an inference?

• By guessing the outcome of an event.

• By providing observations that align with the inference.

• By changing the inference to fit the evidence.

• By ignoring contradictory evidence.

What distinguishes an observation from an inference?

• Observations can change, but inferences cannot.

• Observations are always true, while inferences are guesses.

• Observations are data collected through senses, while inferences are interpretations of that data.

• Inferences are more accurate than observations.

Which of the following is an example of using an observation to draw a conclusion?

• Assuming it will rain because the sky is dark.

• Noticing that a plant's leaves are drooping and concluding it needs water.

• Believing a friend is mad because they didn't say hello.

• Predicting a team will win based on their past performance.

What is a key aspect of making an inference?

• Making a statement without any prior observation.

• Using evidence to form a logical conclusion.

• Stating facts gathered from observations.

• Making a random guess.

Why is it important to differentiate between observation and inference in scientific investigations?

• To ensure that conclusions are based solely on what is directly observed.

• To make sure that all inferences are proven as facts.

• To clearly separate data from the interpretations of the data.

• To avoid collecting data through observations.

Which of the following best describes an inference?

• A direct measurement of temperature using a thermometer.

• The sound of thunder following a flash of lightning.

• Predicting rain due to dark clouds in the sky.

• Counting the number of seeds in an apple.

How does drawing a conclusion from observations differ from making an inference?

• Drawing a conclusion is based on multiple observations, while an inference can be based on a single observation.

• Conclusions are always correct, whereas inferences can be wrong.

• Inferences are made before observations, while conclusions are made after.

• There is no difference; they are the same process.

What role does evidence play in making inferences?

• Evidence is not necessary for making inferences.

• Evidence provides a basis for making logical inferences.

• Evidence contradicts inferences, making them stronger.

• Evidence is only used after inferences are made to prove them right.
