Observations vs. Inferences in Science

What are the primary senses used in making scientific observations?

• Smell and sight only

• Sight and hearing only

• Sight, hearing, touch, smell, and taste

• Touch and taste only

What is the difference between an observation and an inference in science?

• An inference is a guess based on observations.

• An inference involves using equipment, while an observation does not.

• An observation involves guessing, while an inference is based on senses.

• An observation and an inference are the same.

Why is it important to support inferences with observations?

• To make the observations valid

• To make sure the inferences are correct

• To comply with scientific methods

• To make the experiment more interesting

What can be visually observed in the provided picture scenario?

• A new tire and clean surface

• A shiny metal surface

• A flat tire, rust, and sand

• A broken glass

Based on the sand, what inference was made about the location in the picture?

• It might be underwater

• It might be in the desert

• It might be in a forest

• It might be in a city

What inference was made about the temperature of the location in the picture?

• It is freezing

• It is moderately warm

• It is very cold

• It is very hot

What does the appearance of the wheel well suggest about the vehicle?

• It is borrowed

• It is recently painted

• It is very old

• It is brand new

Why might the tire in the picture be considered not fixable?

• Because it is too large

• Because it is still usable

• Because of the visible white threads

• Because it is very clean

What should be done if new observations do not support an existing inference?

• Ignore the new observations

• Change the observation method

• Revise the inference

• Repeat the observations
