Science Lab Safety 10th Grade Quiz - Quiz

Are you in 10th grade? What do you know about lab safety? We have come up with the science lab safety 10th grade quiz for you. Labs are an important part of science students. It's the place where students get to learn about various chemicals, do different experiments, and get to learn things practically instead of just reading theories from books. However, safety is a big concern when dealing with dangerous chemicals. These questions will not only test you but will aware you more.


Questions and Answers
  • 1. 

    Closed-toed shoes are an ideal choice for labs.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Closed-toed shoes are an ideal choice for labs because they provide protection for the feet. In a lab setting, there may be hazardous materials, sharp objects, or spills that can cause injury. Closed-toed shoes offer a barrier against these potential dangers, reducing the risk of accidents and injuries. Additionally, closed-toed shoes also prevent any chemicals or substances from coming into contact with the feet, which could cause burns or other harmful effects. Therefore, wearing closed-toed shoes is a necessary safety precaution in labs.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Wearing earphones during a lab test can be potentially dangerous as it can prevent the person from hearing important instructions, warnings, or alarms. It can also distract the person from focusing on the task at hand, leading to potential accidents or errors. Therefore, it is not okay to wear earphones during a lab test.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Wearing contact lenses while dealing with chemicals can be dangerous as chemicals can get trapped between the lens and the eye, causing irritation or injury. Contact lenses can also absorb chemicals, leading to further damage. It is recommended to remove contact lenses before working with chemicals to protect the eyes and maintain eye health.

    Studying the floor plan before the experiment is important.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Studying the floor plan before the experiment is important because it allows researchers or participants to familiarize themselves with the layout of the area where the experiment will take place. This knowledge can help them navigate the space more efficiently and effectively during the experiment, reducing the chances of accidents or mistakes. It also allows them to plan the placement of equipment or materials in advance, ensuring that everything is organized and accessible during the experiment. Overall, studying the floor plan beforehand can contribute to the smooth execution of the experiment and improve its accuracy and reliability.

    One should always look in the test tube from the side.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Looking in the test tube from the side is important because it allows for accurate observation of any changes or reactions occurring inside the tube. When looking from the top, it can be difficult to see small details or changes, and the angle may distort the view. By looking from the side, one can ensure a clear and unobstructed view of the contents, enabling better analysis and interpretation of the experiment.

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A beaker should be used to heat liquids because it is specifically designed for heating substances. Beakers are made of heat-resistant glass and have a wide and flat bottom, which allows for even distribution of heat. They also have a pouring spout and a handle, making it easier to handle hot liquids safely. Additionally, beakers have clear markings on the side, allowing for accurate measurement of the liquid being heated.
