TEKS: Lab Safety Test! Quiz

When entering a science lab, it is important to sit quietly and wait for the teacher to give instructions. This is because science labs often involve dangerous equipment and chemicals that require specific handling and precautions. By waiting for the teacher's instructions, you ensure that you are aware of the safety protocols and procedures that need to be followed. This helps to minimize the risk of accidents or mishaps in the lab and ensures a safe and productive learning environment for everyone.

Eating food in the lab is dangerous because there are chemicals and bacteria present that could contaminate the food. This can lead to potential health risks if the contaminated food is consumed. Additionally, it is important to maintain a clean and sterile environment in the lab to ensure accurate and reliable results. Eating in the lab can introduce unwanted substances and compromise the integrity of experiments or research being conducted.

Joe should ask the teacher what he needs to do next because the teacher is the person who can provide guidance and clarification on the activity. Copying what his friends are doing may not be the correct approach as they might also be unsure. Guessing what to do next is not a reliable solution as it may lead to mistakes or wasting time. Starting the activity again without seeking guidance would be unnecessary and may not address the problem. Asking the teacher is the best way for Joe to get the necessary information and continue with the activity.

The correct answer is to wash your hands. This is important because touching pets can transfer germs and bacteria to your hands, which can then be easily spread to other surfaces or even to yourself if you touch your face or eat without washing your hands. Washing your hands helps to prevent the spread of germs and keeps you and others safe and healthy.

Erika should tell her teacher about the accident because it is important to inform someone in authority about any accidents or incidents that occur. This will ensure that appropriate action can be taken to clean up the water and broken glass, and to prevent any potential hazards or injuries to others. Additionally, notifying the teacher shows responsibility and accountability for her actions.

Sandals should not be used when working in the lab because they do not provide adequate protection for the feet. Lab work often involves handling hazardous chemicals, sharp objects, or potential spills, which can pose a risk of injury. Closed-toe shoes are recommended for lab work as they provide better protection and reduce the risk of accidents.

In a science lab, it is important to follow safety rules and regulations. Drinking anything in the lab, including water, is not allowed as it can lead to contamination or ingestion of harmful substances. Therefore, the correct answer is "None of the above. You may not drink anything in the science lab."

It is important to clean up if you break something in the science lab in order to maintain a safe and organized environment.

The correct answer is "all of the above" because when working with chemicals, it is important to use equipment such as gloves, goggles, and lab coats to protect oneself from any potential hazards. Similarly, when working with sharp objects, like knives or scissors, it is necessary to use protective gloves or finger guards to prevent any accidental injuries. Lastly, when working with sand, it is recommended to wear protective clothing, such as coveralls or dust masks, to avoid inhaling or getting sand particles in the eyes or skin. Therefore, all three scenarios require the use of specific equipment for safety purposes.
