Use steady ideal resistors and an ideal fixed source. Series resistors share a current: P = I x I x R, so the larger resistance dissipates more power within that pair. Complete parallel branches share a voltage: P = V x V / R, so the smaller resistance dissipates more power. The condition held equal matters. Use paper models only, not a physical build.
Worked example
At a shared series current of 0.02 A, a 100-ohm resistor dissipates 0.02 x 0.02 x 100 = 0.04 W and 200 ohms dissipates 0.08 W. At a shared parallel voltage of 6 V, their powers are 36 / 100 = 0.36 W and 36 / 200 = 0.18 W. Changing the layout changes what is equal.
