Science Safety Contract Quiz

Why does Evelyn need to sign the Science Safety Contract before participating in a chemistry experiment with Liam and Sophia?

• To ensure a safe classroom environment for all students

• To conduct experiments without supervision

Answer explanation

The purpose of the Science Safety Contract, as the question suggests, is to ensure a safe classroom. This is because safety is paramount in any science lab or classroom where experiments are conducted. The contract is not meant to allow students to conduct experiments without supervision, which could lead to accidents or misuse of equipment.

During a science lab, Emma, Harper, and Abigail are discussing safety rules. Which of the following is NOT a safety rule mentioned in their contract?

• Wear safety glasses or goggles when instructed

• Touch any equipment, supplies, animals, or other materials without permission

Answer explanation

The question asks for the safety rule that is NOT mentioned in the contract. The correct answer is 'Touch any equipment, supplies, animals, or other materials without permission'. This implies that the contract does not allow touching any equipment, supplies, animals, or other materials without permission, making it the correct choice.

Kai and Mason are working on a science experiment in class. Abigail is their teacher. They are unsure about a step in the experiment. What should they do if they do not understand the instructions?

• Remove their safety glasses or goggles

• Ask Abigail, their teacher, questions

Answer explanation

The question asks what to do if the instructions are not clear. The correct choice is to ask your teacher questions. This is because if you don't understand something, it's always best to seek clarification from someone who knows, like your teacher. Removing safety glasses or goggles doesn't help in understanding the instructions.

Grace, Priya, and David are in the science lab. When should they conduct their experiments?

• Only when their experiments are authorized and approved by the teacher

• When the teacher is out of the room

Answer explanation

The question asks when one should conduct experiments. The correct answer is 'Only when authorized and approved'. This is because conducting experiments without proper authorization or approval can lead to safety risks, ethical issues, and legal problems. Therefore, it's crucial to ensure that any experiment is authorized and approved before it's conducted.

Emma, Ethan, and Harper have just finished their science experiment in the lab. What should they do before leaving the science room?

• Wash their hands with soap and water

• Remove safety glasses or goggles

Answer explanation

The correct answer is 'Wash your hands with soap and water'. This is because it is a standard safety procedure to clean your hands after a science experiment to remove any potential harmful substances. Removing safety glasses or goggles is also important, but the question specifically asks about what to do before leaving the room, hence washing hands is the correct choice.

Evelyn and Grace are working on a science project in their school lab. Mason, their lab instructor, is supervising them. When should they wear safety glasses or goggles?

• Only when they are conducting experiments involving chemicals

• They should never remove their safety glasses or goggles while in the lab

Answer explanation

Safety glasses or goggles should be worn at all times in the laboratory, not just during experiments involving chemicals. This is because there could be unforeseen accidents or incidents that could potentially harm your eyes. Therefore, the correct answer is 'Never remove safety glasses or goggles'.

What should you do with the equipment at the end of the experiment?

• Return it clean and in working order to the proper storage area

• Keep it for future experiments

Answer explanation

At the end of an experiment, it is important to return the equipment clean and in working order to the proper storage area. This ensures that the equipment is ready for use in future experiments and maintains a safe and organized laboratory environment. Keeping the equipment for personal use is not a responsible practice and can lead to disorganization and potential hazards.

Anika, Henry, and Emma are working on a chemistry experiment in the lab. They notice a small chemical spill on the floor. What should they do?

• Report it to the teacher immediately

• Wait for someone else to report it

Answer explanation

In case of an accident or hazardous condition, it is crucial to report it to the teacher immediately. This ensures that the situation is addressed promptly and appropriate measures are taken to prevent further harm. Waiting for someone else to report it may lead to delays and increased risk.

During a biology class, Hannah and James are asked to handle a rabbit for their experiment. How should they handle the rabbit in the science room?

• They should wear gloves when handling the rabbit

• They should keep the rabbit close to their faces

Answer explanation

The correct answer is 'Wear gloves when handling them'. This is because it is important to maintain hygiene and safety when dealing with animals in a science room. Direct contact can lead to the spread of germs or potential allergic reactions. Therefore, wearing gloves is a necessary precaution.

Mason and Emma are in a chemistry lab. They found a piece of glassware on the table. How should they handle it?

• They should use extreme caution and handle it with care

• They should throw it away in the regular trash

Answer explanation

The question asks about the proper way to handle glassware. The correct choice is to use extreme caution and handle it with care. This is because glassware is fragile and can easily break, potentially causing injury. Throwing it away in the regular trash is not a safe or responsible way to dispose of glassware.
