Question

the passage below describes a process of scientific inquiry. select the part of the passage that describes analyzing the data. hint: to analyze the data, you examine the data and look for patterns. after a severe ice storm, dale wondered how he could melt ice on the sidewalk. he had heard that sand, when heated by the sun, could melt ice. so, dale got twenty ice cubes that were equal in weight. he sprinkled sand on half the ice cubes and left the other half unsanded. he placed all the cubes outside for one hour and then brushed off the sand and reweighed them. dale calculated the average weight of each type of cube to see if the sanded cubes melted more than the unsanded cubes. he decided that sand did not speed up melting, since the two types of ice cubes were similar weights. then, he read that salt makes ice melt at a cooler temperature. he predicted that because the melting temperature would be lowered, ice cubes would melt faster if he applied salt to them.

Explanation:

Analyzing data involves examining the data to look for patterns. In the passage, Dale calculated the average weight of each type of cube (sanded and unsanded) to see if sanded cubes melted more than unsanded ones and made a conclusion based on the comparison of their weights.

Answer:

Dale calculated the average weight of each type of cube to see if the sanded cubes melted more than the unsanded cubes. He decided that sand did not speed up melting, since the two types of ice cubes were similar weights.
