Uva Virtual Lab: Capacitors and Resistors in Parallel

Why do the bases in DNA pair up the way they do? Unravel the mystery of the double helix in a virtual lab. Young scientists follow in the footsteps of Watson and Crick to determine the free energy associated with DNA base pair binding....

How to calculate the current through a resistor in parallel using equivalent resistance and Ohm's law. [4:32]

In this simulation the cell will be used to charge a capacitor. The capacitor will then be used to operate a light bulb until the capacitor is discharged.

Understand how an electric current flows in a circuit through an illustration of a water tank pushing water.

This source describes a water flow analogy of two batteries in series as a two-stage gerbil powered waterwheel. Check out the video clips.

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.

Textbook problems with a twist! Young chemists analyze an ionic reaction to identify the limiting reagent. They then make calculations to determine the concentration of unknown solutions. Finally, they put their work to the test and...

Hiking chemists have an advantage! Young scholars use a virtual lab to conduct an experiment to create an exothermic reaction. The goal is to create enough heat to warm a meal during a hike in the rain.

Colorful cobalt complexes make a great way to learn about Le Chatelier! Eager chemists explore equilibrium through a virtual lab. Individuals use solutions with two different concentrations and observe the color changes that indicate...

Combine a little solid and a little water and the solution is clear! An experimental lesson has individuals make calculations to create a sample solution of a given volume and molarity. They then create the solutions using a virtual lab...
