Scientists use seismic waves to study Earth's interior. Seismic waves travel through the Earth and can be detected far from their source.
Some scientists observe the natural world by doing experiments outside or in a plant or animalâ??s natural habitat. Other scientists may study cells of organisms under microscopes to find out more about them.

Scientists do not observe Mercury as often because it is difficult to do so.
In earlier times, scientists primarily relied on sky gazing to observe heavenly objects. Later telescopes were made use of. Today we have a huge network of telescopes based both on earth and its orbit constantly observing the sky.
it depends on the size of the To_observe_a_small_living_organism_a_scientist_might_use_a. If it is microscopic, then scientists might have to observe it using it using a microscope. If it can actually be seen, then scientists mught actually take a sample of it back to the labratory to observe physically
Tools enable scientists to make more accurate observations, and to observe things that they otherwise could not observe. For example, microscopes allow scientists to observe bacteria, which otherwise are too small to see.
Scientists observe pretty much everything. Clues can be anywhere.

Since the surface of the Earth is exactly where scientists (and the rest of us) live, scientists have had excellent opportunities to observe it, and they know stupendously vast numbers of things about it. I wouldn't even attempt to summarize such an enormous body of knowledge.

The instrument scientists use to observe the planets is a high powered telescope.
Our best scientists only know it to be prehistoric. I DO know that some of it is SO delicate, we should only observe it from a distance.
