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 an object out...

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...

Buoyancy
Swimmers know to float by turning their bodies horizontally rather than vertically, but why does that make a difference? In an interesting lesson, scholars explore buoyancy and the properties of air and water. They test cups to see which...

Ships 2: What Floats Your Boat?
Students design, build, and test the specifications (water displacement and load line) for a model boat. The instructional activity focuses especially on integrating design principles with inquiry-based experimental skills.

Ships 3: Grand Designs And Great Failures
Students engage in this, the third in a three-part series on ships. The overall lesson series is designed to allow students to extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing...

Grand Designs And Great Failures
Young scholars extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. students discover that most ships are constructed very similarly-whether they are schooners or...

The Stone Boat Mystery
Students design and execute a lab through which they study the distinctions between density, buoyancy, and volume.

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...

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 presentation continues...

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...

Who Sank the Boat?
Fifth graders experiment with student-made aluminum boats to test for buoyancy. They design a boat and determine how many marbles it takes to sink it while recording their data in a spreadsheet. They design a graph using the data and...

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...

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 pennies...

Buoyant Boats
Learners 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.

Creating the Ideal Cargo Boat
Students build boats out of clay to test the buoyancy of the boat in water. Students break into pairs and construct their boat to specific guide lines, then experiment with their boat in the water.

Activity: Float a Clay Boat
Written to introduce pupils to buoyancy, this activity has collaborative groups work to design a floatable clay boat. They first observe that a stick of clay sinks in water and then are given their own stick to reshape into a floating...

What Floats Your Boat?
Learners are introduced to the concept of buoyancy. The Video used in this lesson demonstrates and explains the characteristics of objects that sink and float. It presents the concepts of displacement, weight, and buoyancy.

Barge Building: What Floats Your Boat?
Students construct aluminum foil boats that float while holding the greatest number of pennies. They investigate the concept of water displacement, record their results, and watch a Bill Nye video on buoyancy.

What Boat Designs Float the Best?
Fifth graders investigate buoyancy by conducting a science experiment. In this water properties instructional activity, 5th graders predict which of their different paper boat designs will float for the longest period. Students conduct...

What Floats Your Boat?
Students explore the principles of buoyancy and Archimedes' Principle and design their own flotation device. They compare the dimensions of a model to the real object to determine scale and analyze the models to suggest improvements.

Floaters and Sinkers
Whatever floats your boat. Young engineers learn about density by measuring the masses and volumes of boxes filled with different materials. Using their knowledge of densities, they hypothesize whether objects with given densities will...

TinkerCAD: Introduction to 3D Printing
Steer young minds to build better boats. Future engineers first spend a few days exploring the TinkerCAD software and completing some embedded lessons. They then design sea crafts with buoyancy in mind and print them using a 3-D printer.

Concrete Canoes
Learners explore and analyze the relationship of buoyancy and displacement needed to make an object float. They examine various boat designs, then design and build clay and aluminum boats that hold a cargo of marbles.

Ships to a New World
Students experiment with buoyancy as a force. For this buoyancy lesson, students access an assigned website to examine the sailing vessels that came to the New World. They work as teams to build boats out of aluminum foil to see which...
