Below are sample questions representative of the exercises included on this worksheet and related 5.91 Laboratory Safety Symbols and Procedures skill assessments:

Problem 1Difficulty: Mastery
A final lab plan says: safety-goggles symbol at the mixing station, no-food symbol at every table, handwashing after cleanup, and teacher approval before changes. What does this plan show?
AA plan that makes data collection impossible
BA plan that allows students to taste safe-looking materials
CA plan that uses symbols only for decoration
DA complete safety approach for preventing splashes, ingestion, contamination, and unsafe procedure changes
Solution & Explanation:The plan connects symbols and procedures to real risks: splashes, tasting, contamination, and unapproved changes. That is strong safety planning.
Problem 2Difficulty: Mastery
Which investigation best shows students interpreting safety symbols and using a class safety contract before working?
AStudents begin as soon as materials arrive and guess what symbols mean later
BStudents copy the safety contract after the investigation is over
CStudents choose a station, name the posted symbols, read the matching contract rules aloud, put on required gear, and begin after teacher approval
DStudents let one partner decide all safety steps without discussion
Solution & Explanation:The correct plan includes interpreting symbols, connecting them to contract rules, using required gear, and getting approval before the investigation begins.
Problem 3Difficulty: Mastery
A student cuts a finger on a sharp plant stem during an outdoor observation. Which response order is best?
AHide the cut so the group can keep working
BTell the teacher, stop touching materials, follow first-aid directions, and wash hands when directed
CFinish the data table, then mention the cut
DAsk a friend to inspect the cut with dirty hands
Solution & Explanation:Injuries should be reported immediately. Work stops until the teacher gives first-aid and cleanup directions.
