LEAP Interpreting Scientific Data 3

Question 1

A data table shows the boiling points of five liquids. Liquid C has the highest boiling point. What conclusion can be drawn?

Accepted Answer

Liquid C requires the most heat energy to change to a gas

Answer

A higher boiling point means more heat energy is needed to convert the liquid to a gaseous state.

Question 2

A scientist graphs distance traveled over time for a car. The line becomes steeper after the midpoint. What does this indicate?

Accepted Answer

The car increased its speed

Answer

A steeper slope on a distance-time graph indicates greater speed — more distance covered per unit of time.

Question 3

Experimental data shows that three trials gave results of 5.1, 5.0, and 5.2 grams. A fourth trial gives 8.9 grams. What should the scientist do?

Accepted Answer

Investigate the fourth trial for possible error before including it

Answer

When one result differs greatly from the others, the scientist should check for experimental error before including it in the analysis.

Question 4

Which graph type is BEST for showing how a population of bacteria changes every hour over 12 hours?

Accepted Answer

Line graph

Answer

A line graph is best for showing continuous change over time, making it ideal for tracking bacterial population growth.

Question 5

A table shows the number of bird species observed in different habitats: Forest=42, Wetland=38, Desert=14, Grassland=27. Which habitat has the greatest biodiversity of birds?

Accepted Answer

Forest

Answer

The forest habitat has the highest count of bird species (42), indicating the greatest bird biodiversity.
