In this lesson students will learn about the stratification of the ocean by using a simulation to show the different densities. The simulation explores how temperature, salinity, and wind affect the development of water stratification.

Concluding a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate densities of several household liquids and compare them to the densities of irregularly shaped objects (as...

Describes the properties of seawater and the variations depending on its location, e.g., near a shoreline, in an estuary, or as sea ice. Discusses the instruments scientists use to measure the density of water and explains other...

In this demonstration, students will brainstorm to find a solution as to why Diet Coke floats and Coke sinks. Through this exercise students will arrive at a definition of density.

This highly informative site delves into salinity, pressure, density, temperature acoustics, and optics associated with ocean water. A quick quiz follows the information presented.

Use water displacement and a mass balance to determine the density of various objects in this interactive simulation.

Use water displacement and a mass balance to determine the density of various objects in this interactive simulation.

In this experiment, students look at Deep Hypersaline Anoxic Basins, or DHABs, that are present in the Eastern Mediterranean, and make a model of a DHAB to investigate how liquids that have different densities can form layers. This...

Learners investigate the properties of water in the ice and liquid phase as it relates to convection in the ocean and density driven circulation, and ultimately the climate.

After reading some facts about the properties of water, students conduct experiments to measure the relative densities of water, ice and snow and submit the results to the website.

An experiment in density where colored water, both hot and cold, are poured into containers of water at room temperature. Students will observe that the warm water rises and the cold water sinks due to their different densities.

Directions for a lab that compares the density of a marble, wood, water and two different types of candy bars.

Students will use two different methods to determine the densities of a variety of materials and objects. The first method involves direct measurement of the volumes of objects that have simple geometric shapes, while the second uses the...

In this first part of a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate the densities of several common, irregularly shaped objects with the purpose to resolve confusion...

Students act as chemical engineers and use LEGO MINDSTORMS NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and...

A lesson where students learn how warm water is less dense than cold water, and what this means for global climate change as ice from the polar regions melts. Students will do experiments in buoyancy and water density when hot or cold,...

Do heavy things always sink and light things always float? In this introductory demonstration and activity, students are introduced to the concept of density as they explore a rock and a wooden block in water.

Learners use the water-displacement method to find the volume of different rods that all have the same mass.

An interactive simulation that teaches about pressure, fluids, and density by observing changes in pressure under and above water with changes in variables including fluids, gravity, container shapes, and volume. This simulation can...

Students are introduced to the fundamentals of environmental engineering as well as the global air, land and water quality concerns facing today's environmental engineers. After a lesson and activity to introduce environmental...

Because different liquids have different properties, density also differs. In this activity from the Illinois Institute of Technology, students will calculate densities of water, dish-washing detergent, cooking oil, and other liquids.

A simple lab experiment for students to find the density of two solids and a liquid (does not use water displacement). Note that number 1d should not state "weighs" since mass is being found.

Tells the story of how Archimedes discovered the Archimedes Principle and his water displacement method for determining the volume and density of an object. Provides an explanation and several examples of how it is done.

Through this curricular unit, students are introduced to the important concept of density. The focus is on the more easily understood densities of solids, but students may also explore the densities of liquids and gases. Students devise...
