Part 1 – 30 minutes
. This video discusses buoyancy, density, mass and Archimedes principle.
- Watch the video on buoyancy.
- Explain we are building a boat to hold the maximum amount of mass
measured in pennies.
- Pass out aluminum foil, popsicle sticks, clay, corks, hot glue gun and
pennies.
- Using these materials, design a boat to hold the most pennies.
- Make sure it can float without leaking.
- Slowly and evenly add pennies, count how many it can hold.
- Calculate the surface area of the bottom of your boat, that touches
the water.
- Place the surface area and number of pennies your boat held in your
data table.
- Copy your classmate data into the data table.
