Part 1 – 30 minutes
. This video discusses buoyancy, density, mass and Archimedes principle.
https://www.youtube.com/watch?v=nMlXU97E-uQ Buoyancy – what makes something float or sink.
  1. Watch the video on buoyancy.
  2. Explain we are building a boat to hold the maximum amount of mass measured in pennies.
  3. Pass out aluminum foil, popsicle sticks, clay, corks, hot glue gun and pennies.
  4. Using these materials, design a boat to hold the most pennies.
  5. Make sure it can float without leaking.
  6. Slowly and evenly add pennies, count how many it can hold.
  7. Calculate the surface area of the bottom of your boat, that touches the water.
  8. Place the surface area and number of pennies your boat held in your data table.
  9. Copy your classmate data into the data table.
