Use an electron microscope

Professor Johnson enters the lab where you are getting ready to set up your experiment.

Professor Johnson: "What are you working on? You seem very enthusiastic!"

You: "We're planning to use the electron microscope to observe a wet mount of pond water."

Professor Johnson: "I suggest you reconsider your approach. For a wet mount you need a technique that is better suited for imaging samples in their native hydrated state without the need for extensive sample preparation."

You: "That makes sense. Thank you for the advice, Professor. We'll rethink our approach and choose a more suitable technique for our experiment."

Professor Johnson: "You're welcome. Remember, it's important to consider the limitations and requirements of the equipment you're using to ensure the success of your experiments. If you need any further guidance, feel free to ask."

You reconsider your approach, thanking the professor for the advice and discuss alternative microscopy techniques with the other students.
