Illustrated tutorial explains the numerous factors which shape ocean currents. Animations help students visualize how these aspects constantly affect the water movement in the ocean and how scientists use this information to study ocean...

This site gives background information to ocean water and its contents. It has a link to an detailed chart showing the minerals and their content amount in ocean water. It also has links to activities.

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...

Demonstrate the effect that dissolving different amounts of salt in water has on the density of the liquid.

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.

An introduction to density, mass, and volume with links to related books and activities.

In this science experiment, you will learn about density while making water fireworks!

Investigate the science behind this age old question. Find out the role density and polarity play in the liquids.

In this chemistry field lab, students will determine the density, pH, and water content of 4 types of soil. Students compare class data and write a lab report describing their results and then analyze their findings to report on the...

Discover how the molecular make-up of water affects its density.

Learn how the molecular movement in different temperature water affects the density of the liquid.

In this activity, students will learn about density by determining how to make an egg float in water. By the end of the lesson, students will understand that density and weight are different and that density matters in floatation. They...

Investigate density by floating an ice cube on the surface of cooking oil and observe what happens as it melts.

A United States map showing density levels of animals raised for food, accompanied by effects of factory farming and latest news on farming, animal welfare and food safety.

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.

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

In simple terms, density is the mass of anything - including air - divided by the volume it occupies. In the metric system, which scientists use, we usually measure density in terms of kilograms per cubic meter. The air's density depends...

Demonstrate the relationship between water temperature and density using two clear plastic soda bottles.

Learn about the relationship between vapor pressure of water and capacity of air to hold water vapor, the relationship between relative humidity and partial pressure of water vapor in the air, and how to calculate vapor density,...

This large PDF file integrates math, science, and language into several lessons about characteristics of the oceans. Topics include ocean currents, tides, density, marine life, and pollution.

Students study the chemical characteristics of the World Ocean, water chemistry, element cycles, and chemical resources in this multi-media learning module.

A student learning module with a focus on the relationship of temperature and salinity with density, ocean-influenced weather patterns, and how light and sound move through ocean water.

Learn how salt increases the density of water and creates a condition of buoyancy.
