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...

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...

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...

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

Why does ice float? In this article answer that question by learning about the topics of Specific heat capacity, evaporative cooling, and heat of vaporization of water.

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

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...

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...

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.

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

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

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...

This lab experiment has students observe and compare the density of five different liquids while measuring mass and volume.

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

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

This experiment demonstrates the density of selected liquids.

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

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

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 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.

This lesson introduces students to the important concept of density. The focus is on the more easily understood densities of solids, but students can also explore the densities of liquids and gases. Students devise methods to determine...

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...

In this inquiry lab activity, students will attempt to layer 6 different kinds of soda pops in a large test tube using their knowledge of density and other physical properties of liquids.
