Question

if you wear contact lenses in the school laboratory, take them out before starting the lab. you do not have to wear protective goggles. advise your science instructor that you wear contact lenses keep the information to yourself. if you do not understand a direction or part of a lab procedure, you should figure it out as you do the lab. try several methods until something works ask the instructor before proceeding skip it and go on to the next part

Explanation:

• For the first question: In a school laboratory, it is important to inform the instructor about wearing contact lenses as they need to be aware for safety reasons. Taking them out before starting the lab is not always practical or necessary if proper safety measures (like wearing goggles) are in place. Not wearing protective goggles is incorrect as goggles are a general safety requirement. Keeping the information to yourself is unsafe as the instructor may not be able to provide appropriate guidance.
• For the second question: If you don't understand a lab procedure, asking the instructor before proceeding is the safest and most correct approach. Figuring it out as you do the lab or trying several methods until something works can be dangerous in a lab setting where incorrect procedures can lead to accidents. Skipping it and going on to the next part may lead to incomplete or incorrect understanding of the overall lab.

Answer:

• First question: advise your science instructor that you wear contact lenses
• Second question: ask the instructor before proceeding
