Lab Report Assistant

This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions, diagrams if needed, and data tables that should be addressed in a formal lab report. The intent is to facilitate students’ writing of lab reports by providing this information in an editable file which can be sent to an instructor.

Observations

Questions
Part 1

A. What happened when you brought the rubbed ruler close to the paper, salt, and pepper? * the salt and pepper and the little papers had friction and got attracted to the ruler.

1. Were all three substances affected equally? - No only friction because rubbing was only done.

2. What explanations can you offer for why this happened?
- I suggest that this happened because when you rub two things hardly obviously there is friction going on. Also I tried it with my hair even though that wasn’t told but the same results happened. The rest of the substances did not occur because they were not instructed to apply.

B. What combinations of cloth and ruler seemed to produce the greatest effects? * The rabbit fur and the red cloth. But the greatest was the fur.

Part 2

A. Why do you think the charged ruler affected the original suspended strip as it did? * Because of the static the tape had while it charged in the desktop. As I pulled the tape it was charged so the ruler attracted the tape because I also charged the ruler with the rabbit fur.

B. What happened when you brought the two separated tapes close to each other? What explanations can you offer
