Salt 'n Lighter
Source Institutions
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.
From Here to There
Source Institutions
In this water activity, learners discover ways to move water across the water table.
Float My Boat
Source Institutions
In this activity, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?
Above Water: Buoyancy & Displacement
Source Institutions
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
Rescue Mission
Source Institutions
In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.
Boats Afloat
Source Institutions
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.
The Best Dam Simulation Ever
Source Institutions
This online simulation game explores the different consequences of water levels on the Columbia River in the Pacific Northwest.
Bridge the Gap
Source Institutions
Learners work in groups to construct bridges using stale marshmallows and toothpicks.
Draggin' Boats
Source Institutions
Learners design, build, and test models of "dragon boats" made from up to three milk cartons.
Float Your Boat
Source Institutions
In this physics activity, learners will explore buoyancy.
Watercraft
Source Institutions
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.
Design a Submarine
Source Institutions
Learners act as engineers and design mini submarines that move in the water like real submarines.
Soapy Boat
Source Institutions
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.
Aluminum Boats
Source Institutions
Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?
Pop Can "Hero Engine"
Source Institutions
In this activity, learners build water-propelled engines from soft drink cans.
Great Steamboat Race
Source Institutions
In this outdoor activity, learners race small boats, made of cork, balsa wood, popsicle sticks etc., to investigate the rate and direction of currents in a stream or creek.
