Homework Help: Planning and Designing a lab on Coupled pendulums

My teacher told me plan and design about 4 labs, okay the thing is I'm not sure about the layout of P/D for physics labs.

I know there has to be expected results, I'm confused I don't know what to put there.

My teacher gave me a lab manual to try and guide me okay, in the book at the end of the method for this Coupled Pendulum lab it asks me to plot a graph, how can i do that without values?

What should I do?

You could calculate how the values should look like?

Hmm... but how would I know what they should be near to ?

Which type of graph do you try to plot?
If you don't know parameters of your coupled pendulums, find some plausible numbers. Like a length of ~50cm, a harmonic coupling with ~5% of the strength of the individual pendulums, some weaker damping (like <1%/cycle or even 0) or similar values. Solve the system, plot the time-evolution of the system.

Oh thank you, one more thing could you tell me the layout of a p/d lab my teacher didn't tell me. I know you're supposed have a hypothesis and expected results and so on.

I don't understand what you are looking for.

I mean like for a p/d lab you would have

-Title
-Aim
-Hypothesis
-Apparatus/Materials
-Variables
-Procedure
-Data Collected
-Treatment of Data
-Discussion (limitations, sources of errors)

but is this all?
