Lab Activity Place the graduated cylinder on the floor behind your chair. For the next 60 seconds, one of the partners will kneel on the chair facing backwards and will try to drop the pennies into the graduated cylinder. Your hand must stay above the back of the chair. Every 10 seconds, your partner will record how many pennies you made in. Follow the steps above with each of your lab partners until everyone has gone. Analyze your data and create a line graph using all of your information.
