A group of 2 people will be responsible for setting up and running each lab. While one person in your group runs your lab for other students, the other person in your group will visit another lab. You will take turns in running your own lab so that each of you has an opportunity to collect data in each lab. For each lab you will record a set of paired data points (at least ten data pairs for most labs). Record these data pairs in list 1 and list 2 of your TI-83, 83 plus or 84 calculator (or any calculator that has list and STAT capabilities) so that you can create a scatter plot for each lab (independent variable in list 1 and dependent variable in list 2). Also keep a paper record of your data pairs.
There are two ways to collect this data:
The data from this experiment are needed for your Assignment 16, so please save your data!
Create a small fulcrum on which to balance a meter stick (a thick marker works fairly well but you will need to find a way to stop it from rolling). Record the balance point of the meter stick (e.g. 50 cm). Place one penny on the beginning of the meter stick (between the 0 and 2 cm marks). Move the meter stick so that it balances. Record the new balance point of the meter stick (e.g. 47.5 cm). Add a second penny on top of the first penny at the beginning of the stick and repeat the procedure. Continue repeating the procedure for a maximum of ten pennies on top of each other.
