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 use tinfoil to build and test their own boats - which designs will float, and which will sink?
In this activity, learners explore watercraft engineering and sailing.
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
In this design challenge, learners build a boat that paddles itself using a rubber band as its power source.
In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.
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 surface tension. Why are certain objects able to float on the surface of water and how do detergents break the surface tension of water?
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 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, learners explore how boats are engineered to achieve speed.
Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?
In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.
