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...

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.

How Does the Density of a Liquid Affect the Buoyancy of an Object?
Here's a lesson plan that will really float your boat! Introduce physical science scholars to the relationship between buoyancy and density through an assortment of individual and collaborative exercises. Lab groups work together to...

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...

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...

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?
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: Who Sank the Boat?
Students examine whether objects will sink or float. In this buoyancy lesson students bring in objects and experiment to see if they sink or float.

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...

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.

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...

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.

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.

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...

Floating Fishes: Boat Sinking Lab
Cut milk cartons in half to make boats and let investigators attempt to sink them. They add dividing walls and observe what happens if marbles are put into only one of the newly formed compartments. Vocabulary is provided: buoyant force,...
Curated OER
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.

Sink or Float?
Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

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...

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...

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...

Sink or Float
Using a variety of objects, learners conduct buoyancy experiments. They make predictions on which object will sink or float and test their predictions. They use a graphic organizer to record their findings.
