what is the difference in the melting points of saturated and unsaturated fatty acids?
how can i draw/make a diagram to illustrate this?

Saturated fatty acids have higher melting points than unsaturated fatty acids.
Saturated fatty acids have a "linear" ish structure, so they're easier to pack together, so more energy is needed to separate them. Unsaturated fatty acids have "kinks" in them (usually caused by double bonds between the carbons) so they're more difficult to pack together and it's easier (less energy required) to separate them.
To illustrate this, I would just draw a fatty acid with like a 12 or 14 carbon chain. For the saturated one, the carbons will all have C-C single bonds. For the unsaturated one, add a double bond to create a kink in the chain (C=C).
