Let's Lab!

We spent today taking three sets of data:

• The time for a ball to drop 1.5 meters from rest
• The distance a projectile travels before hitting the ground
• The mass of one washer

The goal was to have these things in your lab notebook for each set of data:

• A short procedure
• organized data
• a description of one random and one systematic error and how they affected your data (how did they affect precision, accuracy, or both)

The idea behind today was for you to work through some common data gathering mistakes. To that end, I wandered around asking (extremely) leading questions while you were taking data in an attempt to steer you in the right direction. You will have a grade for today, but if you were here and participating you received 100%.

If I did not have a safety contract from you, you were not allowed to interact with lab supplies.
