Science Safety Contract Quiz

Why does Bernadette need to sign the Science Safety Contract before participating in a physics experiment with her friends, Sheldon and Howard, in their apartment?

• To ensure a safe laboratory environment for all participants

• To conduct experiments without supervision

• To allow horseplay and pranks in the physics lab

• To eat and drink in the physics lab

Answer explanation

The purpose of the Science Safety Contract is to ensure a safe classroom environment for students and teachers. This contract sets guidelines and expectations for proper behavior, handling of materials, and use of equipment during science activities. It helps prevent accidents and promotes a responsible attitude towards safety in the science room, making the first option the correct choice.

En un episodio de The Big Bang Theory, Raj, Howard, Sheldon, Amy y Leonard están trabajando en un laboratorio de química. Se les da un contrato de seguridad para seguir. ¿Cuál de las siguientes NO es una regla de seguridad mencionada en el contrato?

• Siga todas las instrucciones escritas y verbales cuidadosamente

• Toque cualquier equipo, suministros, animales u otros materiales sin permiso

• Use gafas de seguridad o gafas de protección cuando se le indique

• Mantenga su área de trabajo y la sala de ciencias ordenada y limpia

Answer explanation

The correct answer is 'Touch any equipment, supplies, animals, or other materials without permission' because it is NOT a safety rule mentioned in the contract. The other options are safety rules that emphasize following instructions, wearing protective gear, and maintaining a clean workspace.

During a chemistry lab experiment at Caltech, Sheldon and Leonard are unsure about the next step in synthesizing a compound. What should they do?

• Touch the lab equipment without asking

• Ask their supervisor, Dr. Gablehauser, for clarification

• Have a snack or drink in the lab

• Remove their safety glasses or goggles

Answer explanation

If you do not understand the instructions, it is important to ask your teacher questions. This ensures that you receive proper guidance and clarification, preventing any potential accidents or misunderstandings. Touching equipment without permission, eating or drinking in the science room, and removing safety glasses or goggles are all unsafe practices and should be avoided.

Sheldon, Bernadette, and Howard are in the chemistry lab working on a project inspired by The Big Bang Theory. When should they conduct their experiments?

• When the teacher is out of the room

• Only when authorized and approved

• Whenever they feel like it

• When the teacher is present

Answer explanation

Conducting experiments should only be done when authorized and approved, as it ensures safety and adherence to guidelines. Unauthorized experiments can lead to accidents, damage to equipment, or incorrect results. Proper authorization ensures that the experiment is conducted under supervision and follows established protocols.

After conducting a chemistry experiment in their apartment, what should Leonard, Sheldon, and Raj do before leaving for the comic book store?

• Wash their hands with soap and water

• Eat or drink something

• Remove safety glasses or goggles

• Touch their face, eyes, and mouth

Answer explanation

The question asks about the necessary action before leaving the science room. Among the given options, washing your hands with soap and water is the most appropriate. This is because it ensures that any chemicals or substances that may have come into contact with your hands during the experiment are thoroughly cleaned off, ensuring safety.

During a filming of The Big Bang Theory, the actors playing Amy, Leonard, and Sheldon are demonstrating a chemical reaction experiment for a scene. When should they wear safety glasses or goggles?

• Only during scenes involving chemicals

• Never remove safety glasses or goggles

• Only when the director is watching

• Only when handling the prop hamster

Answer explanation

Safety glasses or goggles should be worn at all times in a lab or any environment where there is a risk of eye injury. This is not limited to experiments involving chemicals or handling animals, and it's not about whether the teacher is watching. The correct answer is 'Never remove safety glasses or goggles' because safety should always be a priority.

After completing a chemistry experiment in their apartment, what should Sheldon, Leonard, and Penny do with the equipment they used?

• Leave it on their living room table

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

• Throw it away

• Keep it for themselves

Answer explanation

The question asks about the appropriate action to take with the equipment after an experiment. The correct choice is to return it clean and in working order to the proper storage area. This is because it's important to maintain the equipment for future use and to keep the workspace tidy. Other options like leaving it on your work area, throwing it away, or keeping it for yourself are not appropriate.

During a filming of The Big Bang Theory, Kaley Cuoco (who plays Penny) accidentally knocks over a bottle of vinegar on the set. What should Melissa Rauch (who plays Bernadette) and Kevin Sussman (who plays Stuart) do in this situation?

• Report it to the director immediately

• Ignore it and continue with their scene

• Handle it themselves

• Tell their co-stars

Answer explanation

The question asks what to do in case of an accident or hazardous condition. The correct response is to report it to the teacher immediately. This is because the teacher is the authority figure in the classroom and is trained to handle such situations. Ignoring the situation, handling it yourself, or just telling your classmates could lead to further harm or damage.

During a scene in The Big Bang Theory, Professor Sheldon instructs Penny, Leonard, and Raj to handle a hamster for their experiment. What is the correct way for them to handle the animal in the lab?

• Tease and handle it roughly

• Take it out of the lab

• Wear gloves when handling it

• Keep it close to their faces

Answer explanation

In a science room, it is important to handle animals with care and respect. Wearing gloves when handling them is the correct choice, as it ensures the safety of both the animals and the handler. Teasing or handling animals roughly, taking them out of the science room, and keeping them close to students' faces are all inappropriate and potentially harmful actions.

Abigail is working in a chemistry lab with Sheldon from The Big Bang Theory and needs to handle glassware. What should she do?

• Pick up hot or broken glassware with her bare hands

• Use extreme caution when using matches, a burner, or hot plate

• Cut towards her body

• Handle it with care and respect

Answer explanation

The correct way to handle glassware is with care and respect. Glassware can be fragile and easily broken, so it's important to handle it gently to avoid accidents. Picking up hot or broken glassware with bare hands, using extreme caution with matches, burners, or hot plates, and cutting towards your body are all incorrect options as they do not specifically address the handling of glassware.
