Question

1. lamar is conducting an investigation to figure out if there are living things in a sample of water. he gets the microscope from the shelf while carrying his goggles in his other hand. he drops a glass microscope slide and breaks it. he tells the teacher immediately, and his teacher cleans up the glass. did lamar break any safety rules?

a. yes. he should have cleaned up the glass on his own.
b. yes. he should have carried the microscope with two hands.
c. no. lamar followed all safety rules.
d. yes. he should have been working under a fume hood.

Explanation:

When carrying a microscope, it is a safety rule to use two hands. Lamar was carrying the microscope with one hand (the other hand had goggles), which is a violation. Cleaning up broken glass by a student (option a) is unsafe as it could cause injury. A fume hood (option d) is for dealing with toxic fumes, not relevant here. Since Lamar broke a safety rule (carrying microscope with one hand), option c is incorrect.

Answer:

B. Yes. He should have carried the microscope with two hands.
