In this activity (on page 2 of the PDF under GPS: Sailboat Design Activity), learners will discover how the shape of an object, not just its weight, determines whether it floats or sinks.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

Learners act as engineers and design mini submarines that move in the water like real submarines.

This activity (on page 2 of the PDF SciGirls Activity: Milk Carton Boat) is a full inquiry investigation into boat hull design.
