Answer:

The student response demonstrates a complete understanding of the

task by generating four questions regarding the properties of the

unknown powder that could be safely tested and answered in the

laboratory. The response is focused and relevant to the task. The response provides four acceptable questions that could be safely tested and answered in

the laboratory. Question 1, regarding solubility, is acceptable. Question 2, regarding density, is

acceptable. Question 3, regarding reaction with other substances, is acceptable. Question 4,

regarding heating the powder, is acceptable. Note that mention of “boiling point” is an error;

solids melt, but this does not keep the response from earning a score of 4.
