For the pairs of molecules in parts A-D below, one of you build the first molecule and the other build the second molecule. If the models you each built can be made to look identical to each other by means of bond rotations without breaking any bonds then the molecules are the same. If molecules contain the same number of each type of atom, but they cannot be made to look identical without breaking bonds, then they are isomers (they are not the same).
