In science our project for this week is to discover the amount of passengers (pennies) our lifeboat (a modified paper cup) can carry. We must, sadly learn vocabulary words such as: buoyancy and surface tension. Also the current record holder is Cameron, Zach, Charlie, Christian and Josh with a record-holding 35 pennies.
On Friday we constructed our lifeboats by taking paper cups with wax covering and cutting them to exactly three cm. After we had to get 50 pennies to act like our passengers. To control the variables, we must only use pennies that were minted 1983-2010 because before 1983 the US Mint had a higher copper content creating a heavier penny.
Then we went to work going into groups trying to create the best way to pattern our pennies on the cup. This is one of the most important if not the most important part of this. If we didn’t evenly distribute the pennies we do very good imitation of the Titanic we weren’t aiming for that. We hope we can get 45+ pennies this week.
