so they can share their information with other scientists or so they can have all that they have recorded before so that they have proof from their experiment.

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.
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
