8th Grade Science Lab Safety Essentials Quiz

Before starting a lab, it is essential to clear off the lab table to create a safe and organized workspace for conducting experiments.

It is crucial to immediately report any spilled chemical to your teacher as they are trained to handle such situations and ensure proper safety measures are taken.

It is important for safety reasons that students only fill burners with fuel at the designated burner filling station in the back of the room to prevent accidents or mishaps.

Chipped or cracked glassware poses a safety hazard as it can break further during use, potentially causing harm. It is important to report any damaged glassware to your teacher to ensure it is properly handled.

It is never safe to taste chemicals as they can be harmful, even if they taste good.

A test tube rack is used to hold test tubes upright to prevent them from rolling or spilling. It is different from a Bunsen Burner, Pipette, or Petri Dish, which have different functions in a laboratory setting.

Safety glasses should be worn in the lab when there is a potential risk of chemicals, heated substances, burners, glassware, or any substance that could harm the eyes. Wearing safety glasses only when using sharp objects or working with paper and pencils is not sufficient to ensure eye safety in a lab setting.

Loose clothes and jewelry can pose a safety hazard in certain environments, so it's important to remove or tie them back to prevent accidents.

Flip-flops are not suitable for lab settings due to the lack of protection they provide to the feet. It is important to wear closed-toe, protective footwear to minimize the risk of injury or accidents in a laboratory environment.

Running in the lab poses a significant safety risk due to the presence of potentially harmful chemicals, fragile equipment, and other hazards. It is important to prioritize safety in the lab environment to prevent accidents and ensure the well-being of yourself and others.

Goggles are designed to protect your eyes from potential hazards, so they must be worn over your eyes to provide the necessary protection.

Test tubes should always be placed in a test tube rack to prevent them from rolling off the table and to ensure proper organization and safety in the lab.

Tongs are typically used for gripping and lifting objects, while a spatula is a flat cooking tool, a whisk is used for blending ingredients, and a peeler is used to remove the skin of fruits or vegetables.

The question is asking for the number of burners that can be used at one time, and the correct answer is 'ONE' because only one burner can be used simultaneously.

Test tubes should be carried in a test tube rack to prevent accidents and spills.

Safety precautions dictate that only authorized personnel, such as the teacher, should handle lighting the burner to prevent accidents.

A pipette is a laboratory tool commonly used in science experiments for accurately measuring and transferring small volumes of liquid. Beakers, microscopes, and Bunsen burners are other common laboratory tools, but they serve different purposes.

Carrying a lit burner is extremely dangerous as it can cause burns, fires, or explosions. It is crucial to never carry a lit burner to prevent any accidents or harm.

Lab safety is a collective responsibility that involves everyone in the lab environment, including both the lab instructor and the students. Ignoring safety measures can result in accidents and injuries, so it is important for everyone to be vigilant and accountable for adhering to safety protocols.

Heating glassware until it is dry can cause it to shatter due to thermal stress. It's important to always keep glassware wet when heating to avoid this risk.

The correct answer is Flask as it specifically refers to a small container for carrying a small amount of liquid.

In a science lab, it is important to keep long hair pulled back to prevent it from getting in the way or coming into contact with chemicals or equipment that could be potentially hazardous. Loose hair, a braid, or a hat could all pose safety risks in a lab setting.

When checking if a container is hot, it is best to use the back of your hand as it is more sensitive to heat than the palm. This technique helps to prevent burns or injury by allowing you to feel the heat without having direct contact with the hot surface.

Reaching over a flame is never safe as it can result in burns or other hazards. It is always best to exercise caution and avoid reaching over any kind of open flame.

The correct answer is 'Burner Stand', as it is a stand used to hold a burner in place while cooking or heating food. The other options, 'Cooking Grill', 'Fire Pit', and 'Portable Stove' are different items used for cooking or heating but are not specifically designed as a stand for a burner.

The item in question is specifically designed for the process of evaporation in chemistry experiments. While a beaker is a common laboratory glassware, it is not the correct answer in this case. Mortar and Pestle is used for grinding and Bunsen Burner is used for heating.

Before using burners, it is important to check for cracks to ensure safe operation. Rust, loose connections, and dirt may also affect the performance of the burners, but cracks are the main concern as they can lead to gas leaks and potential hazards.

Boiling chips are typically non-toxic and can be poured into a strainer in the sink for proper disposal.

The correct answer is 'Rubber Stopper' because it is a common laboratory item used to seal test tubes and flasks to prevent leakage or contamination.
