1. Experiment 3 part 2 – Feedback and recap of part 1 – Lab 3: Terminal Velocity Experimentalists and Theorists Goals for this lab: o How accurately can you measure the terminal velocity of 10 and 15 coffee filters stacked together? o How accurately can you predict the terminal velocity of 10 and 15 coffee filters from your past data?

2. – Design teams (theorists): – Use your data from last week to predict the terminal velocity for 10 and 15 coffee filters staked together. – Company evaluation teams (experimentalists): – Design an experiment to measure the terminal velocity of 10 and 15 coffee filters stacked together. – Design teams present their results to the class. – Company evaluation team presents their results to the class and chooses a winning design team. Experiment 3 part 2

3. Things to think about... – Design teams: What does your graph of terminal velocity versus number of filters look like? Does it make sense to take more data? Are your results reliable? How are you going to present your results? – Company evaluation team: Do you need another experimental setup (maybe outside the lab room) to take your measurements? What questions are you going to ask the design teams to help you make your decision?
