Which of the following best describes an observation?

• A guess based on perceptions

• An opinion about something

• Objective and based on senses

• A prediction about the future

Which example is an inference?

• The ground is wet.

• The sky is blue.

• It rained.

How do scientists gather information and design investigations?

• By making random guesses

• Through observations and inferences

• By copying others' work

• By ignoring evidence

If you see that the ground is wet, and you think "someone spilled something," what are you doing?

• Making an observation

• Making an inference

• Stating a fact

• Giving an opinion

Which of the following best describes an "observation" in science?

• Objective; based on senses

• Subjective; based on perceptions

• Data based on quantities

• Designing a solution

What is the main difference between qualitative data and quantitative data?

• Qualitative data is based on numbers, quantitative data is based on qualities

• Qualitative data is based on qualities, quantitative data is based on quantities

• Both are based on measurements

• Both are based on perceptions

Which of the following is an example of a task that involves strategic thinking in science?

• Designing a solution (technological design/engineering)

• Recalling the definition of inference

• Listing types of data

• Naming the senses used in observation

Why is background research important when asking scientific questions?

• It helps understand what has already been done

• It provides quantitative data

• It is used to make observations

• It is only needed for engineering solutions
