Keep Your Boat Afloat
Use whatever material floats your boat. Working in groups, scholars decide on a type of metal and a type of coating to use for building a boat. They test their creations by leaving their boats in a pool of water for several days before...
NOAA
Boat Building Challenge
Scholars build a boat using an assortment of materials such as foam plates, aluminum foil, and skewers, then test its buoyancy with pennies. Challenge boat builders to construct the strongest or fastest boat in a healthy competition with...

Clay Boats
Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Everyday Engineering: Foil Boats
Keep one's dream of becoming an engineer afloat. Learners apply the engineering design process to build a boat out of aluminum foil. They start with a square boat, then consider whether boats of different shapes would be able to hold...
Cornell University
Build a Fuel Cell
Discover the connection between redox reactions and fuel cells. Collaborative groups build a Hoffmann Apparatus that demonstrates the electrolysis of water and then convert their models into a fuel cell. They use their fuel cells to...

Buoyancy Boats
What did the sea say to the boat? Nothing, it just waved. An inquiry-based lesson starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats. Then, they design...

Physics of Boats
Let's go sailing! An instructive unit includes six lessons with multiple activities to teach scholars about density, center of gravity, buoyancy, and the Archimedes Principle. They can complete the final project of building a boat...

What Floats Your Boat?
This open-ended boat building exercise is meant to be part of a three-lesson series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat, find its load line...

What Floats Your Boat?
Clay's as good a material as any to build a boat, right? An introductory lesson sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

Paddle Boat
Harness the power of rubber bands of all things. A hands-on activity has scholars design and build paddle boats. They learn how the elastic potential energy of rubber bands can be converted to the kinetic energy associated with motion.

Building a Compound Light Microscope
What better way to learn how to use a microscope than building your own? A lab investigation has scholars use lenses from magnifying glasses and sheets of cork to design their own compound microscopes. They calculate focal length...

Foil Boats
How many pennies can an aluminum foil boat hold? That is the challenge in a collaborative activity designed to explore the concept of buoyancy. Learners use aluminum foil to build makeshift boats and test the weight they hold before...

Curious George Sailboat
A whole-group discussion kicks off a hands-on activity that challenges young engineers to build a sailboat using reusable materials. Participants gather recycled items to assemble their one-of-a-kind sailboat and test its ability to...

Watercraft
Whatever floats your boat—with some additional weight. The first activity in a five-part series challenges pupils to design a boat to hold pennies. Using the design process, learners design, build, and test their boats, making sure they...

Buoyant Boats
Students design and construct a boat out of aluminum foil and a few other simple materials. The boats then be tested by floating them in water, then adding mass until they sink. They explore the various shapes of boat construction.

Transportation Systems: Two Liter Boat Activity
Students design and build full-size boats made out of two-liter plastic bottles, chicken wire, and plywood. Then they race the boats, with the boat's designers "manning the hull", in the school's swimming pool.

Dragon Boats
Students create a model boat. In this art lesson plan, students identify what makes a boat float and use milk cartons to create their own boat.

Boat Hull Design
Working in small groups learners develop three alternative boat designs. They discuss the rationale for the type of hull, propeller, location of ballast, and type of building material used in their design. They build their boat.

How a Sailboat Works: Hull Speed and Buoyancy
How can you determine the maximum speed of a sailboat? A sailing presentation included with a straightforward lesson plan prompts learners to calculate the maximum speed of a sailboat with a displacement hull. The...

Buoyant Boats
Fourth graders explore the concept of mass and buoyancy. After building boats out of several materials, they predict whether each boat floats if certain objects are added. Students test their predictions and draw conclusions from their...

Paddle Power
Potentially get all the way across the water. The fourth of five design challenges asks pupils to develop a plan for a paddle-powered boat that will store its energy. Given a limited number of supplies, the class members design, build,...

Bridge Building
Bridge the gaps in your knowledge of bridges. Individuals learn about bridge types by building models. The activity introduces beam bridges, arch bridges, truss bridges, and suspension bridges.

Design a Flotation Device
Save the soup! Scholars devise a flotation device using straws, balloons, foam, corks, and other objects. A can of soup must stay afloat for at least a minute with this device—your dinner might depend on it!

A Weighty Issue
Want to get your students motivated in science class? Given only a piece of aluminum foil, assign groups the task of designing a "barge" that will support the weight of a bunch of pennies. The group who is able to put the most...
