Here's a sample Lab #1 write-up I made for your reference.  Anything in italics (other than captions) or highlighted text is a side note for you, the AP student trying to make sense of this write-up process.

The College Board made this to help with lab analysis.  Among other things, it's good for learning about linearization (starting on page 10).

This is a worksheet to help understand significance in measurement.  This helps you judge how many digits are worth recording for a given measurement.

In this single page memo, the college board outlines specifically how well things should be explained here.  It's worth a quick read.  It's the standard I try to hold you to myself in all written responses (labs, tests, quizzes, homework).

Metric prefixes and sig figs

Here's a copy of the syllabus for BST AP Physics 1

Rotational motion automatically has energy from the spin...  Now we know!  These questions are for you to add to the analysis so you can fix the data (no new measurements required!)

Here's an intro to momentum for us to try.  What's conserved before and after a force is applied?  We'll investigate that here.

We're determining the mass that rotates around our heads when tied to a string that goes through a tube and is tightened by a mass hanging from the end.  The analysis here is more interesting perhaps than it seems at first...

Lab#1: Mass on Spring and Period of Oscillation

Relate period of mass oscillating on a spring to the mass to analyze data and relate proportionalities.
