Mislabeled bottles can cause a dangerous situation! Young chemists design a method for determining the true contents of a solution in a virtual lab activity. Their study of density helps them identify the makeup of the solution.

A metal's density could be considered its fingerprint! A virtual lab activity has learners calculate the density of a sample of metal to make its identification. The simulation allows individuals to perform the measurements as if they...

Assume the role of Canadian border control! The percent of alcohol and density of a solution are related. Young scholars use this fact to classify solutions by their alcohol content to determine if they meet Canadian import laws.

Recreate the secret Coca-Cola formula in a virtual lab. Young scholars create the solution and then calculate sucrose concentrations in terms of percent mass, molarity, molality, and mole fraction. Then using density, learners...

This simulation begins with an exploration of water pressure and atmospheric pressure. In the flow portion, scholars reshape a pipe and see fluid dynamics at work. The water tower portion encourages pupils to determine how water...

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.

Determine the concentration of an alcohol solution from its density.

In this activity, students use the virtual lab to identify three unknown metals by measuring their density and comparing their measurements to the densities of known metals. In this randomized version, each student designs and performs...

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 lab is designed to help students discover the connections between the linear density of a string and the tension in the string with the speed of the wave along the string. The program can be set with six identical strings or six...

This lab was designed to allow students to collect data for the Force Gravity vs. Volume lab for materials and locations that we cannot do in the classroom. Students will fill the bucket to different levels and record the force on the...

In this activity, students use the virtual lab to identify an unknown metal by measuring its density and comparing their measurements to the densities of known metals.

This map shows population change among whites in US counties, 1840 to 2000. Each dot represents 500 people. Corresponding historical events and elections are included for each period of time.
