The Mathematics of Convection: Nature's Model for Energy Production
High schoolers conduct a series of experiments to investigate density, buoyancy and climate. In this math lesson, pupils design and build a hot air balloon to demonstrate convection. They research and write a paper about solar chimneys.
Curated OER
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...
Curated OER
To Float or Not to Float - Density
Students experiment floating a variety of objects in various liquids. They discover how density affects the ability of an object to float and apply the concept of density to solve problems.

Buoyancy Bulls-Eye
Why does a seastar sink, but a jellyfish float? Through a fun investigation, learners examine the concept of buoyancy using simple household items. The challenge: create neutral buoyancy for an action figure in water. With ample teacher...
CK-12 Foundation
Going Fishing
Why do some things float and others sink? A creative simulation allows learners to adjust mass and volume of an object to affect its buoyancy in water. A graph records the effect of each manipulation.
University of Waikato
Buoyancy in Water
Change where an object floats in water. Pupils experiment with a Cartesian diver by squeezing on the side of a plastic bottle. Learners pay attention to the bulb of the pipette as the bottle is squeezed to determine what is happening...
Curated OER
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...
Curated OER
Sink It
Introduce your class to the concept of sinking and floating. In groups, they classify objects after making predictions about which materials will sink or float. They record their results and create graphs and charts to share with the class.
Curated OER
Grand Designs And Great Failures
Students 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 destroyers.
Curated OER
Ships 3: Grand Designs And Great Failures
Middle schoolers engage in this, the third in a three-part series on ships. The overall instructional activity series is designed to allow students to extend their understanding of floating, sinking, density, and buoyancy and apply it to...
Curated OER
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...

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...
Curated OER
How Does the USS Alabama Float?
Students investigate buoyancy. For this buoyancy lesson, students apply the Archimedes Principle of Buoyancy to the experiment conducted in class to determine how battleships float.
