Answer 2

When starting to observe a specimen under a microscope, it is best to use the **4X scanning (lowest power)** objective lens first. This lower magnification allows you to locate and focus on the specimen more easily, providing a wider field of view. Once the specimen is centered and in focus, you can then switch to higher power objectives, such as the 100X lens, for more detailed observation. Using the lowest power first helps prevent damage to the slide or lens and facilitates the initial searching process.
