The above points were for general lab reports. Specifically, for the Galileo lab report:

Your abstract should mention what you actually did in your experiment. The terms falling, acceleration, and gravity are important. What were your actual results? What does theory say you should get?

Your introduction needs to use a primary source. You should mention Galileo and his historical role in what you are about to present. You may mention other historical figures. You should define velocity and acceleration. You should explain the equation for the Law of Falling Bodies and provide a derivation of that equation. You should explain the connections between inertia, Newton’s 1^{st} Law, gravity, weight, Newton’s 2^{nd} law, and why g is constant for all objects.

Your procedure needs to provide explicit details of the experiment and how it was performed. Do not present results. Make sure you have annotated or explained diagrams, photos, or sketches.

Your analysis needs to have a data table with an explanation. You should have a graph of the position data with a best quadratic fit. There must be an equation and an explanation of the graph. You should be able to show your calculation of g from that graph, and an error comparison to published values. You should explain possible sources of error.

Your conclusion should recap the big ideas (acceleration and gravity) you showed. You should recap the procedure, results, and errors (briefly). You should have proposals for future work.

Your appendix should include the bibliography (with primary sources), tables, graphs, pictures, sample calculations, etc.
