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...

How do the densities of vegetable oil, water, and corn syrup help them to form layers in a cup? Students will carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are...

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...

Students determine whether a liquid will sink or float in water by comparing its density to the density of water.

In this activity, students will investigate whether the temperature of water affects its density. Students will place colored hot and cold water in a cup of room-temperature water to see that cold water sinks while hot water floats. Then...

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...

A lab activity to show students how different densities of liquid layer on top of each other by using four different colored liquids that contain different levels of salinity. This activity can also be used in an ocean unit where...

After students conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson plan to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the...

In this activity, students use the virtual lab to design an experiment to determine the identity of mislabeled bottles using the densities of the solutions inside.

This activity explores the property of density in a variety of liquids and solids.

In this science activity, you will stack several liquids, one by one, and create a colorful density column.

An activity to help you create a density column that contains layers of liquids that are separated by different densities.

Young scholars experiment with liquids; comparing and contrasting, and creating a density tower leading to a beginning understanding of density.

For this activity, young scholars 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.

Students explore the densities and viscosities of fluids as they create a colorful 'rainbow' using household liquids. While letting the fluids in the rainbow settle, students conduct 'The Great Viscosity Race,' another short experiment...

An investigation into what properties liquids have that enable them to sit in separate layers in a container.

This experiment allows you to dramatically demonstrate the different densities of five different common household liquids.

Students explore the concept of density by investigating how several solids and liquids interact. Through hands-on activities and a teacher demonstration, they develop a greater understanding of density by using their observational...

Students first predict, then mix several liquids and then add salt to the mix, simulating a lava lamp.

As part of a larger site called "Getting started in Chemistry," this site examines various topics related to the densities of substances and materials. Included in the study are properties of solids, liquids and gases, and how density is...

This experiment demonstrates the density of selected liquids.

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

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