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 explore how boats are engineered to achieve speed.

In an investigation called "Shape It!" learners craft tiny boats out of clay, set them afloat on water and then add weight loads to them, in order to explore: how objects stay afloat in water; what th

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.

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

In this activity, learners explore how engineering has impacted the manufacturing of canoes over time, including the development of new, durable, and lighter materials.

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

In this activity, learners explore watercraft engineering and sailing.
