Science Inquiry & Data Interpretation Flashcards

A bar graph shows that plant A grew 8 cm, plant B grew 5 cm, and plant C grew 11 cm. Which plant grew the most?

Answer: Plant C

Plant C had the highest bar at 11 cm, indicating it grew the most.

In an experiment, all variables are kept the same except the one being tested. What are the unchanged variables called?

Answer: Controlled variables

Controlled variables are kept constant so they do not influence the results of the experiment.

A student observes that ice melts faster on a dark surface than a light surface. This observation could lead to which testable question?

Answer: Does surface color affect the rate of ice melting?

The testable question directly addresses the relationship between the observed variable (surface color) and the outcome (melting rate).

Which of the following is an example of qualitative data?

Answer: The rock is red and rough

Qualitative data describes characteristics or qualities, not numerical measurements.

A line graph shows temperature increasing from 8 AM to 2 PM then decreasing. What conclusion is best supported?

Answer: Temperature peaks in the early afternoon

The graph pattern — rising then falling — shows temperature is highest at 2 PM, the early afternoon.

Why is it important to have a control group in an experiment?

Answer: To provide a baseline for comparison

A control group provides a standard baseline so results from experimental groups can be meaningfully compared.

A student measures a liquid three times with a graduated cylinder and records 25 mL, 25 mL, and 24 mL. These measurements are best described as:

Answer: Precise but possibly not accurate

The values are very close together (precise) but without a known true value, accuracy cannot be confirmed.
