Experiments done in space are normally done to see the effects of weightlessness (zero-G) on various physical and biological things. Medical experiments are done on Astronauts to see how weightless affects them, both immediately and after long stays in space. Tests of the immediate effects include such things as how their balance organs work in weightlessness. Long term effects include the rates of bone loss, methods to reduce this loss and how various body functions and body chemistry change with increases in time in weightlessness. Experiments on plants and animals include how they grow and whether the space environment causes mutations during reproduction. There are physical experiments such as how fire burns in weightlessness, how many small particles are moving around in the void of space (outside the spacecraft).
