What Floats Your Boat?
Middle schoolers 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.
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.

Archimedes' Principle
Young scholars examine the relationship between density and buoyancy. For this physics lesson students use Archimedes' Principle to complete calculations on buoyancy and a lab activity.
Curated OER
Density - To Float or Not to Float? That is the Question!
Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.
Teach Engineering
Cartesian Diver
Amaze your scholars with an activity that uses a Cartesian diver to demonstrate Pascal's Law, Archimedes' Principle, and the Ideal Gas Law. Groups then repeat the process and make their own diver move up and down in a bottle.

Student Exploration: Density Laboratory
In this density laboratory activity, students complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

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.

Bathtub Physics - Density, Buoyancy and Flotation
High schoolers study Archimedes' Principle, flotation and the reaction of buoyant forces and explain the relationship between density and flotation.

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...
Curated OER
Ice Floats
Young scholars explore the changing density of water. In this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to living...
Curated OER
I've Got That Sinking Feeling
Students design a simple boat and predict how much weight it can carry. They should also discover why objects float or sink and how this can be determined experimentally. A great lesson plan on buoyancy!
Curated OER
Build Your Own Submarine
Students construct their own submarine following a certain procedure. For this physics lesson, students calculate the density of objects using a mathematical formula. They explain why some object floats in water while some do not.
Curated OER
Freshwater/Saltwater "Eggs-Periment"
Students explore water properties by conducting a class experiment. In this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of salt...
Curated OER
Sink or Swim
Learners explore sinking and floating. In this buoyancy lesson, students conduct an investigation dealing with regular and diet soda. Learners drop various soda cans into water and then discuss why some float and some sink.
Curated OER
The Buoyancy Factor
Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...
Curated OER
Sink or Float?
Students analyze the relationship between density, buoyancy, and salinity. In this chemical properties lesson, students read a background activity for the lesson and experiments to the topics. Students discuss the questions and complete...

Volumw Measurement, English System
Eighth graders biew each volume container and discuss where they have seen them in their home, and how they have seen them used. They explore the different names of volume sizes and their equivalents towards one another. Students...
Curated OER
Diving Raisins
Students hypothesize and observe what occurs when raisins are dropped in a carbonated liquid. They examine buoyancy and how density effects ascent and descent.
Curated OER
Come On Down!
Young scholars research the implementation of a research vessel used for ocean exploration. In buoyancy lesson students will construct a device that shows neutral buoyancy.
Curated OER
Day Six: Floater What Ifs
Students observe earth science by examining results from an experiment. In this buoyancy instructional activity, students practice floating different items in two different liquids and identify why certain objects will float and others...

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.
Curated OER
Chemistry: The Case of the Sunken Ice Cube
Students examine a density demonstration involving ice cubes and beakers of water and alcohol. After observing how one ice cube floats in water and sinks in alcohol, they determine which mixture of the two would suspend the ice cube in...
Curated OER
Floating Pencil
Students discover how salt water makes a pencil float better than freshwater by measuring and comparing the lengths of the portion of the pencil that floats above the water surface. They then determine if an unknown water sample is...
