M-STEP Science Inquiry & Data Interpretation 3

Question 1

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?

Accepted Answer

Plant C

Answer

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

Question 2

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

Accepted Answer

Controlled variables

Answer

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

Question 3

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

Accepted Answer

Does surface color affect the rate of ice melting?

Answer

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

Question 4

Which of the following is an example of qualitative data?

Accepted Answer

The rock is red and rough

Answer

Qualitative data describes characteristics or qualities, not numerical measurements.

Question 5

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

Accepted Answer

Temperature peaks in the early afternoon

Answer

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