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.   

Students will explain the Archimedes's Principle. In this lesson on plankton, students will describe three factors that can affect the buoyancy of plankton. This lesson contains extensive background information, extensions, and multiple...

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...

Young scholars explore the changing density of water. For 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...

Learners construct their own submarine following a certain procedure. In 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.

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 on buoyancy!

Young scholars explore water properties by conducting a class experiment. For this buoyancy lesson, students utilize freshwater, saltwater, plastic cups, hard boiled eggs and food coloring to experiment with the floating capabilities of...

Students explore sinking and floating.  In this buoyancy lesson, students conduct an investigation dealing with regular and diet soda. Students drop various soda cans into water and then discuss why some float and some sink. 

Students form hypotheses and carry out an investigation in order to answer a central question: Does soap float? The focus of this lesson is on scientific inquiry, but it incorporates scientific topics such as sinking and floating.

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...

The challenge: determine whether a tank will float. A design activity has groups work as engineering teams in order to determine the stability of given tanks and liquid contents. The teams need to determine the equations to...

Create a cushion of carbon dioxide gas to float some soap bubbles on. Many concepts can be demonstrated through this activity: Carbon dioxide gas is more dense than air Bubbles are semipermeable, allowing only carbon dioxide to diffuse...

Students make and test predictions about sinking and floating, and classify objects according to whether they sink or float.

Learners explore how fish are able to move easily from one depth to another in water.  In this fish lesson students create their own balloon fish. 

Students use plastic bottles, water, and condiment packets to simulate how natural gas comes from decaying ocean plants and animals. In this natural gas lesson plan, students also fill out lab packets and answer exit questions.

Students watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Students will determine whether various objects sink or float in water. They do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e., that...

As part of a larger resource called "Getting started in Chemistry," this page examines various topics related to density and buoyancy. Included in the study are definition of density and buoyancy, measurements, applications, and examples.

For this lesson, students will investigate why the Cartesian diver dives and rises in a 2 liter bottle. They will also, through their own discovery, come up with a question and then change one variable and record their results. Students...

In this lab, learners will use the scientific method to design an experiment that explains how/why a submarine floats and sinks.

By the end of this section, you will be able to define buoyant force, state Archimedes' principle, understand why objects float or sink, and understand the relationship between density and Archimedes' principle.

An interactive simulation that teaches about buoyancy and density by applying various forces and modifying the properties of objects and fluids. This simulation can either be downloaded or played online and includes handouts, lesson...

Instructional module focusing on density as a physical property of matter. Discussion incorporates historical references as well as formulas. Site also includes an interactive practice quiz and links relating to the topic.
