Question

Sara was preparing for a biology lab that included using the light microscope. First Sara washed her hands. Then she picked up the microscope and carried it, holding the base, to her lab bench. She removed the cover and cleaned the lenses using lens paper. Finally, she plugged in the microscope light. Sara's teacher commented that Sara made one mistake when setting up her microscope. What was it?

Answer 1

Answer:

Sara carried the microscope in a wrong way

Explanation:

Microscope is a device which is used to visualize microscopic materials in a magnified way. The magnification is available in variety of powers and can be chosen according to the requirement. Microscope is an expensive instrument and should be handled with utmost care. Therefore, it has an arm which is used while carrying it. To carry a microscope, one should always grab the base by one hand and the arm by other hand so that there is no scope of slipping.

Answer 2

Sara should have held the microscope by the arm and the base, not just the base. That's the one mistake she made.
