The Lab Report is a demonstration of understanding. True, there are some details with the formatting that need to be attended to, however the main focus of your lab writing should be showing that you learned something new (or confirmed previous knowledge), and that you understood the process that brought you to that point.
I expect that if you are writing a formal lab report that you have done the lab yourself and that you are not using other people's data. Unless specifically instructed otherwise, all lab work and lab writing is to be your own and not group work. While you can collect your data as a group, each student is expected to create graphs and do analysis on their own. Using AI to help write your lab is not allowed unless directly instructed to use it. Outside sources need to be cited appropriately with internal citations.
I expect that labs are written using understanding from what we have covered in class. If you happen to have prior knowledge of the topic and would like to include information that has not been covered in class before you need to find a valid source to confirm this information and cite its use in your lab. For example if you want to include Newton's 3rd Law as part of an explanation, but we have yet to cover that in class, you should find resource to cite and introduce that as new information within your paper.
Quantity is not equal to quality. Make every word mean something, and where you can use diagrams, graphs and equations to replace the words. Why write 5 sentences where a picture or an equation says the same thing.
