Question

if a theory is disproven, then all of the observations that support that theory are also disproven

Answer 1

If this is a TRUE/FALSE question, the answer is FALSE.  The theory is an explanation for the observations.  The observations can be correct, but the explanation can be wrong.

 

Example:

 

You correctly observe that the sun appears to rise in the east and set in the west.  You propose a theory that the sun revolves around the earth.  The theory is wrong, but it does not disprove the observation that the sun is seen rising from one end of the earth and setting on the other end of the earth.   

Answer 2

this isn't necessarily true.  For example, many people believed that the earth is flat because it looked that way to them.  It still looks that way to people on earth, but the theory of flat earth has been refuted by the addition of more observations such as those from space and Eratosthenes' evidence of shadows with differing length at the same moment in time and in differing latitudes.
