Science Safety And Science Tools Quiz

1. If you are not sure what to do during an lab or activity

Ask the teacher

Ask a lab partner

Sit and wait quietly

Guess

During a lab or activity, it is important to seek guidance and clarification if unsure about what to do. Asking the teacher for assistance is the best course of action as they are responsible for providing instructions and can provide guidance tailored to the specific task. Asking a lab partner may be helpful, but they may also be unsure or provide incorrect information. Sitting and waiting quietly is a passive approach that may waste time and hinder progress. Guessing is not advisable as it can lead to mistakes or accidents. Therefore, asking the teacher is the most appropriate and reliable option.

2. Safety goggle must be worn when using:

Fire

Sharp instruments

Chemicals

All of the above

Safety goggles must be worn when using fire, sharp instruments, and chemicals because all of these activities pose potential risks to the eyes. Fire can produce sparks or debris that can cause eye injuries. Sharp instruments can cause accidental cuts or punctures to the eyes. Chemicals can splash or emit fumes that can irritate or damage the eyes. Wearing safety goggles provides a barrier of protection against these hazards and helps prevent eye injuries.

3. Which piece of safety equipment is MOST important to wear when working with chemicals that could splash or create fumes?

Gloves

Lab coat

Goggles

Closed-toe shoes

Goggles are the most crucial safety item when dealing with potentially hazardous chemicals. They provide a protective barrier for the eyes, preventing splashes and harmful fumes from causing irritation, burns, or even blindness. While other options offer protection, goggles directly safeguard the vulnerable eyes, making them paramount in a laboratory setting.

4. Goggles are not needed if you wear glasses.

True

False

Wearing glasses does not eliminate the need for goggles. Goggles provide additional protection for the eyes, especially in certain situations such as swimming, working with chemicals, or participating in sports. Glasses may not provide adequate coverage or protection from potential hazards. Therefore, it is incorrect to say that goggles are not needed if you wear glasses.

5. Make sure equipment is clean

Before you use it

After you use it

Both a and b

When you have time

The correct answer is "Both a and b" because it is important to clean the equipment both before and after using it. Cleaning the equipment before use ensures that it is free from any dirt or contaminants that could affect its performance or cause harm. Cleaning the equipment after use helps to maintain its longevity and prevent the buildup of any residue or bacteria. By doing both, you can ensure that the equipment is in optimal condition and safe to use.

6. Which of the following pieces of safety equipment is NOT typically found in a science laboratory?

Fire extinguisher

Safety goggles

Hard hat

Emergency shower

While hard hats are essential safety equipment in construction or industrial settings, they are not typically necessary in a science laboratory. The primary hazards in a lab usually involve chemicals, glassware, and potential fires. Therefore, fire extinguishers, safety goggles, and emergency showers are essential for protecting against these specific risks.

7. I may eat in the classroom when

Ever I want to

With teacher permission

When I am sure it is safe to do so

Never

Eating in the classroom is allowed only when the teacher gives permission. This implies that the student should not eat in the classroom without the teacher's consent. It is important to follow the rules and regulations set by the teacher to maintain a safe and orderly learning environment.
