Gravity is certainly not necessary in order to do experiments. In fact, there are
some experiments that can ONLY be done in zero gravity ... like for example an
experiment to determine how seeds decide which way to send roots and where
to extend the green shoots when there is no 'up' or 'down', or whether fruit-flies
can maintain their sanity in zero gravity and continue their important mating work.

Check navigation, collect data, complete maintenance, and conduct experiments are the kinds of work which astronauts do on space missions. For example, astronauts and cosmonauts may have to engage in checks on the effects of solar winds and weightlessness, repair or upgrade equipment, and verify their vehicle's direction and speed.
It is a place where astronauts conduct experiments
Astronauts ride in a STS (Space Transporation System/Space Shuttle)
We see astronauts floating in space but not on earth.why?
a space lab!
space lab
Astronauts were able to conduct experiments when working in the space station. One of the space stations that was launched was the Skylab in 1973.
do observations, try experiments and more
Astronauts make Earth spin
The disadvantages of Science in Space include wasting of money for the sake of space experiments,Polluting the space with the earth elements,Risking of life by astronauts to conduct space experiments,health problems for the Astronauts and the worst of all wasting a lot of precious time for the space experiments for the sake of little profit.
To continue exploring space, carrying out experiments, and learning how to live in space.

Spacewalk,from repairs,to intalling new experiments
in space astronauts do experiments like growing plants and they fix satelites and they research things on computers.

Most experiments conducted are medical experiments, but fluid mechanics experiments, various experiments involving weightlessness, and testing of new technologies are also conducted.
