In this activity (on page 2), learners create a submarine using a plastic cup. This is a fun way to learn about buoyancy and density. Extensions for this activity, such as adding a propeller or manometer, are also included.
Note: You will also need access to a tank or swimming pool to watch your submarine dive.
Safety note: Learners will need an adult's help to drill holes in the film canister. Learners will also need an adult's help if they use a glue gun to attach the film canister to the plastic cup.
