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...

Six interactive chemistry lessons about density complete with handouts and animations.

In this activity, students will see that a carrot slice sinks in fresh water and floats in saltwater. Considering the placement of the carrot slice in water and salt water, students will infer that the density of salt water must be...

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.

In this activity, students see that a can of regular cola sinks while a can of diet cola floats. As a demonstration, bubble wrap is taped to the can of regular cola to make it float. This high-volume but light-weight material increases...

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...

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

Discusses how to calculate the density of water and how density varies depending on the temperature and the salinity. Presents a chart showing the difference in the density of non-saline water for temperatures between 0 and 100 degrees...

Explains what density is, how it is calculated, and how the density of water fluctuates depending on various conditions.

An experiment to test what happens when ocean water hits a freshwater estuary. Each step is demonstrated with photographs and the difference between salinity and density is explained.

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.

The purpose of this lesson plan is to find the density of regular (volume can be with a mathematical formula) or irregular objects through water displacement. Uses actual SI units (g/cubed cm).

This lesson plan helps students discover the relationship between temperature, salinity, and density in coastal marine waters. Students access and retrieve water column profile data from the NANOOS and/or the WA Department of Ecology's...

Of course it can, you say: ice is water and ice floats. And you're right. But we're talking about water in the liquid phase Can liquid water float on water? The goal of this project is to investigate what happens to layers of water with...

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.

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.

In this science inquiry, students investigate whether volume or density of objects determine the floating or sinking in water. Using a rock and a block of wood teachers engage students in the discussion of density, mass and volume.

For this activity, students investigate whether objects and liquids float or sink when placed in water. As they proceed, they will develop an understanding of what density is. Student handouts are provided.

See how different liquids can have different densities depending on their molecular make-up.

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

Students investigate water by estimating how long it takes to freeze, then see if the ice cube will float in water, and eventually work with other items to see if they sink or float in water.

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.
